in the not-too-distant future
strange craft resumed across our skies these are not UFOs they’re not alien
craft from another planet these are machines developed and built by human
engineers and designers today’s science fiction will become
tomorrow’s reality these are the aircraft of the future what you are about to see is a glimpse
into the future of aviation winged aircraft as we know them will
soon be a thing of the past aviation technology today is probably
about to undergo some of the most impressive and revolutionary changes
that we’ve seen since the Wright brothers
across the world designers are racing to create fantastic new aircraft that can
fly humans higher faster and further than ever before new military designs
airliners that can take us to the edge of space and around the planet in
minutes and new propulsion systems that will make the jet engine obsolete
forever one casualty of this race for the future sits abandoned on an airfield
this fighter is more advanced than aircraft and service but it is already
obsolete it was the loser in the engineering
competition of the century in 1985 the US Air Force demanded a new fighter
plane one that would incorporate the most up-to-date advances in stealth and
agility two multibillion-dollar designs by rival
companies took to the air in a fight to the death
one was the yf-23 it had diamond-shaped wings the other was the yf-22 the winner would become the backbone of
the US Air Force the loser a billion dollar pile of scrap a fierce fight was about to take place
between the two most advanced fighter aircraft ever built the test pilots fought to outperform
each other but after the yf-23 s wheels touched the
ground it never flew again with its greater performance and agility
the yf-22 was chosen to take the US air force into the next millennium
it is a truly remarkable craft it will be able to reach speeds and perform
maneuvers far beyond the reach of the present frontline fighter
the f-15 even though it doesn’t look enough radically different from all
other airplanes have been built it is very much different the engines the
airframe are all tuned to go fly around supersonic and it’ll be the most
maneuverable airplane that’s ever flown there the key to the yf-22 success is in
its advanced composite materials these absorb radar and give it the same
signature as a small bird it’s tail fin sweep back behind the
engines to shield the jet exhaust from heat-seeking missiles to preserve its smooth outline its own
weapons are hidden inside internal bomb days even its fuel tank cat is hidden beneath
its shark like skin building and testing any new fighter is
a process that would be impossible without the bravery and dedication of
the test pilots this airplane has been a part of my life
for the last 10 years and getting it to this point and getting it in the air it
actually takes a lot of effort I’m not sure I got it in me to do it again the yf-22 incorporates the latest in
thrust-vectoring technology jet engines are pushed along by their exhaust gases
if these are redirected by adjustable nozzles the tail of the plane can be
pushed around much faster with thrust vectoring a fighter can change direction
more quickly the yf-22 was expected to dominate the air for 20 years but there
is a rival on the horizon it also uses thrust vectoring this plane may be the
ultimate fighter of all time it may even be faster than the Y of 22 and is
without any doubt more maneuverable in close combat this is the Sukhoi 37 it
looks like any other fighter but it can perform impossible maneuvers fighter aircraft are traditionally fast
but very heavy which makes them difficult to turn the Sukhoi 37 can perform heart-stopping
maneuvers that defy gravity for any other fighter these maneuvers would be
well beyond their flight envelope they would stall and crash thrust-vectoring and small canard wings
on the nose allow the pilot to throw the su-37 around the skies like an aerobatic
plane 20 tons of military metal can reverse
direction instantly this amazing agility would give it a
decisive edge in combat on its first public appearance its pilot
issued an open challenge to dogfight against all comers
no one took up the offer the sukhoi is master of the skies but with fighters becoming faster the
pilots are getting left behind in the search for ever more maneuverable planes
it’s the pilots themselves that are now the weak link to beat the punishing physical effects
of high G maneuvers the US Air Force looks for a particular type of pilot the
shorter and more compact they are the higher the G’s that can take they are
now conducting tests to see if women are the perfect shape for the combat pilots
of the future major Sharon hice is one of the air
force’s female officers undergoing g-force experiments to test this theory
this centrifuge at wright-patterson Air Force Base can accelerate the pilots
from 0 to 7 G’s in four seconds most pilots blackout at five g’s as the
forces increase blood rushes from the pilots brain towards her feet using
special breathing techniques and inflatable pressure trousers pilots can
counter this effect and take much higher G’s than they could if they were unaided
often as much as 11 GS it’s been rumoured that the data says
that women actually do take the g-forces better tolerate high G’s better than men
but it seems there are still physical limits on the maximum amount of G’s that
any pilot can take you’re not gonna fly beyond about 10 meetings on a regular
basis pilots simply they’re human beings they can’t withstand that what we’re
doing a great deal of however is integrating pilots in with automatic
systems they will not be able to exceed the g-forces but they can perform a lot
of functions that are too fast for pilots to perform by themselves without
the help of computers modern cockpits are crammed with the latest computer
systems soon the pilot won’t even need a joystick steer point move steer point in the near future they
will be able to fly their plane by simply looking in the direction they
want to go new steer point a low-power infrared beam shines into the pilots eye
flight view by analyzing the reflection a computer calculates exactly where the
pilot is looking linked to a control system that can also understand voice
commands pilots will soon be able to talk to their planes even more astonishing is a development
that will allow pilots to fly by thought alone electronic sensors mounted in the pilots
headband detect his brainwaves by concentrating or relaxing the pilot can
manipulate his brainwaves and fly this virtual plane through an obstacle course his task is to try to steer this fighter
through the hoops a black bar allows him to see if he is thinking left right or
straight ahead this simulated flight has no other input no joystick no pedals
with techniques like this pilots of the future will be able to control the most
radical aircraft but the biggest cause of air crashes
remains simple human error and the only way to eliminate human
error is to fly without pilots right now unmanned aerial vehicles are one of the
biggest areas of research and development in the industry this six
foot flying saucer known as cypher is an intelligent surveillance aircraft
developed for the battlefield of the future powered by counter-rotating blades it
can hover or fly up to 60 miles per hour onboard cameras transmit live video
pictures back to base cipher can identify and track hostile targets from
a hundred tanks to a single foot soldier it can take off spy and land without any
control from a human pilot ciphers most deadly asset is its ability to float
through the urban battlefield it can peek around corners or spy
through windows searching out snipers or terrorists with highly tuned sensors one day this machine’s descendants may
patrol our neighborhoods as robotic policemen in the future these may become
the ultimate urban warriors one of the major motivations for using
unpiloted surveillance vehicles is that we don’t have to risk a pilot to get
into very high risk situations we can fly a fairly small aircraft in take
advanced photographs having them transmitted directly without having to
risk the fact that a pilot will get shot down if we shoot down an unmanned aerial
vehicle it cost a few hundred thousand or a few million dollars but we’re not
risking a pilot but the perfect unmanned vehicle would be completely undetectable
it should be quiet without a noisy engine and it should be tiny perhaps
small enough to fly through a window and into a room undetected to meet this
challenge designers are experimenting with radical new concepts and models preflight check rudder control is good elevator control checks trim is good
throttle check that’s fine ready for flight what’s the wind speed
Stewart here we go the aerovironment company in California builds miniature
air vehicles or ma vs for military and civilian use their smallest
remote-controlled surveillance vehicle is a flying disc just six inches across
it’s even equipped with its own onboard video camera and transmitter it’s so
small that it is completely invisible on radar this MA V may look like a toy but
it’s equipped with a satellite navigation system whose battery-powered
propeller it will fly for six miles some of the components that are quite
small on the test aircraft are the flight computer and receiver weighs only
a one and a half grams all together the propulsion motor up front is
approximately five to seven grams one of the challenges of making structures this
size and just handling them is they’re they’re so small that you can’t hold
them with your fingers you can’t see them clearly with the naked eye so you
do have to work under a microscope and you do lose lots of parts when you
sneeze or you just bump the table and that’s just part of the part of the game the same team is also developing
miniature helicopters but there is a major problem in building aircraft this
small as propellers and blades get smaller and smaller they become
aerodynamically inefficient as you get down to these smaller sizes the air
molecule errs seem much larger relative to the wing and the flying becomes more
like swimming through water as opposed to flying through air because of these
difficulties in aerodynamics we’re looking to nature because Nature has
solved all these problems with birds dragonflies and fruit flies already
flapping wing models have been constructed they are always highly
inefficient and never generate as much lift as an insect duplicating the
performance of insect wings is one of the Holy Grails of aviation insect wings
are the most efficient lifting devices on the planet until recently the reason
for this remained a mystery at Cambridge University in England dr.
Charles Ellington has solved the puzzle of how insects generate such incredible
lift it’s a quest that has taken him over 25 years to build a good manager of
a real insect and how it moves its wings we study films and we came up with this
which of course flaps its wings up and down the way you would expect it to do
it also moves its wings perpendicular to that many insects show can the figure of
eight wing motion and we can do this with these two movements then you have
to control the the angle of attack of the wing and to do a good job you have
to control it at the base of the wing and at the tip of the wing so that you
can throw the wing into this cambered profile that you see on the downstroke
is the wing moves down generating lift up like that and then of course you have
to flip the whole thing over because on the upstroke what you have is a reverse
camber like that so the wings moving up generating lift again supporting its
weight but you have to be able to change the shape of the wing all the way from
the base to the tip and from the front to the back at every moment of the wing
beat the technology needed to control and coordinate these four different
types of wing movement is so complex that it has to be controlled by computer
program because the model needed to study the movement accurately is so
large the speed of the wings is slowed down to one beat every two seconds on a
real insect it would be 20 beats per second this model exactly replicates the way in
which the common hawk moth flaps its wings but Charles Ellington’s team also
discovered an unusual phenomenon all right let’s have some smoke by studying
insect wings in smoke they noticed an unusual vortex was created by the
downstroke this observation solved the riddle of how insect wings produced so
much lift the effect was confirmed by a live moth when it was suspended in a
wind tunnel filled with layers of smoke as the wing moves down to cut the very
thin sharp leading edge of the wing moving through the air and just as if
you move a spoon through a cup of coffee you see the flow swirling off that edge
it separates and just swirls up like that into a vortex and a vortex is like
a tornado or a whirlwind it’s a low-pressure region of the air
things get sucked into a tornado and so sitting here with the vortex spinning
like that low-pressure running all along the wing right here and this
low-pressure sucks the wing up and this is what’s producing the extra lift on
the wing and getting to three times more lift out of these wings and out of
conventional ways this machine was never designed to fly
but now that ellington has unraveled the mystery of insect flight soon there will
be miniature na vi’s as small as real insects in the near future three to five
years out will be developing dragonfly sighs microwave vehicles that will be
able to fly down hallways and in windows and in through air ducts packed with
tiny electronics batteries transmitters and with miniature cameras for eyes the
cyborg dragonfly will be a master of disguise with huge amounts of lift it
will be highly energy efficient invisible to radar impossible to shoot
down the only danger it will face will be getting swatted nine eight seven six five four three two
one with no pilot to compromise performance
even more unusual craft and propulsion systems have been designed and tested
this incredible machine was originally designed to shoot down nuclear missiles
and satellites just 12 inches long gyroscopically balanced and with
thrusters at key points around its body it is capable of instant changes of
direction we’re tracking cover no airplane could ever catch this
machine in the 1960s NASA investigated the idea
of whether it was possible to fly an airplane without wings at all the
lifting bodies were a series of experimental wingless gliders built
during the development to the space shuttle the cross section of the
aircraft body is the same shape as a wing producing all the lift needed to
fly these initial low level tests proved so
successful that NASA then built the m2 lifting body it was carried to 50,000
feet by a b-52 bomber and then released as with all radical new designs the
tests were very risky to generate enough lift these early lifting bodies needed
to glide incredibly fast weighing two tons the m2 sent its pilot
plummeting to the earth at over 200 miles per hour gliding at this speed in such an unusual
shape the lifting bodies were extremely difficult to control on its fateful 16th drop the m2 began to
roll wildly just above the runway the craft was destroyed it hit the
ground at 200 miles per hour and rolled 15 times the pilot survived but the
lifting body program was severely setback but in a hangar somewhere in California
the lifting body is ready to make a comeback
Barnaby Wayne fan is a professional designer who worked on the b-2 bomber
he’s turned his attention to the home build market and has resurrected the
lifting body design even stripped down to maintain its secrecy the unusual
shape is still visible the difference really between this and a conventional
airplane is we’ve combined the functions of the wing the horizontal tail in the
body all in one simple shape and because it’s a short kind of thick shape it’s
very light with the light weight I don’t need quite as much aerodynamic
efficiency because I’m not carrying as much load so I’m not working the air is
hard to lift the airplane it looks a bit like a stealth aircraft but the civilian
facet ‘mobile is designed for simplicity it does have some interesting
characteristics the most important of which is that it won’t stall and it
won’t spin and since stall and spin accidents are still a very common cause
of death actually in general aviation that to me was very important because
I’ve eliminated one of the major ways that private pilots get themselves in
trouble often mistaken for a UFO this aircraft may lead to a whole new breed
of home-built aircraft designers around the world are trying to
build radical new aircraft at this once secret Air Base outside Moscow Russian
engineers created what looked more like a flying saucer than a plane called Terry Elka it was conceived
during the height of the Cold War this early secret footage shows the
first scale model tests their methods were low-tech but the results were
remarkably it looked impossible but the tardy Elka flew Russian designers have a
tremendous amount of an imagination and great capability they have been working
under a difficult condition in recent years because they don’t have much money
and therefore it’s hard to get things accomplished but some of the most
advanced aeronautical and space system designs have been done in Russia the
initial tests were so successful that construction quickly began on a
full-size tally Elkin looking like a craft from another planet it could carry
up to a dozen passengers and become the new executive jet of the future
the engines are housed inside the main body the small wings provide no lift at
all they help stabilize and steer the
machine but shortage of money from the Russian
government has already caused work to stop from the target a waterborne version was also tested it
was designed to travel just above the surface of the water using a cushion of
air to provide lift for very little thrust this is called ground effect something
Russian designers had used in their most unusual aircraft this is the Akron
Oakland larger than a jumbo jet it holds the
world record for the greatest lift for any aircraft an amazing 1000 tons this astonishing machine is powered by
eight huge jet engines travels of 300 miles per hour only a few feet above the
ocean and could carry 1000 Soviet Marines since the Cold War the project has been
crippled by financial problems today the original monster sits in
drydock a more familiar way to carry hundreds of passengers around the world
is the 747 it has carried 1.6 billion people and has traveled more than 20
billion miles the equivalent of flying the entire population of Los Angeles and
New York City to the moon and back but with passenger numbers expected to
double by the year 2010 new airliners twice the size of the 747 are needed to
meet the demand an aerodynamics team from NASA Boeing and Stanford University
is developing a new super airliner able to hold a thousand passengers so that
the full-scale version can use the existing airport facilities its overall
wingspan will have to be no greater than the 747 to create the extra room and the extra
lift needed for nearly one-thousand people and their luggage this design has
abandoned the traditional shape of fuselage and wing it has fused the body
and the wing together into a design called the BWB the blended wing body the advantages of this configuration
over a conventional airplane with separate fuselage and engines mounted on
the wings is both in terms of its aerodynamic performance its drag and in
terms of its structural weight so it’s lighter and cleaner aerodynamically this
translates to a predicted fuel savings of as much as 30% the blended wing body
is a concept over 70 years old recently it was used in the ultra stealthy b-2
bomber only the engine exhausts protrude from this futuristic shape this concept
used to be called the flying wing the designers knew that it could carry huge
amounts of cargo or bombs but flying wings have no tail plane versions such
as this YB 49 were highly unstable and almost impossible to control not until
the introduction of computerized technology did the flying wing become
viable again many modern radical designs are intrinsically too unstable to be
flown by hand the technology has gotten to the point that we can now build
electronics and flight control systems small enough to fly inside models of
this size that means that we don’t have to risk a test pilot on a very new idea
we can at the very early stages of a program build something like this and
investigate the most critical and unknown issues onboard computer control
systems are pre-programmed before each test flight with 15 flaps and ailerons
the blended wing body needs more than double the number of control surfaces
far more than a human pilot could handle alone
the pilots tears is normal and the computer then coordinates the numerous
control surfaces with its 17 foot wingspan the blended
wing body model might look like the ultimate in toy aircraft yet this design
could be the shape of the airliner of the future for the design team their first take off
was a nerve-wracking moment the success of the whole project rested on the first
test flight if the model crashed five years of work
and four million dollars would be wiped out in an instant but the first blended wing body model
flight was a complete success in fact it was so successful that it demonstrated
that this radical shape could outperform conventional designs by a huge margin creating a successful new aircraft that
first breaks and then reinvents the rules is what every aircraft designer
lives for we like building things that are different not changing things a
little bit and seeing what happens but rather thinking about what we really
like to have happen and starting with a clean sheet of paper the greatest
challenge of all is speed large airliners like the blended wing body
will remain subsonic Concorde is the only existing supersonic passenger plane
designing an aircraft like this presents an entirely different set of problems in a classic Cold War sting operation
faulty plans of Concorde were leaked to Soviet spies they’re answered a Concorde
the tupolev 144 was a flawed design it crashed in front of the world’s press at
the Paris Air Show in 1973 Concord is the fastest passenger jet
flying it cruises at twice the speed of sound
New York to London in just three hours but there are only 14 of them in service
they only carry 100 passengers and they are very expensive to fuel and service Concord is over 20 years old in that
time no one has taken on the phenomenal task of designing a replacement until
now nASA has recently started work on a new supersonic airliner known as the HSC T short for high-speed
civilian transport it is twice as large as the Concorde and can carry three
times the passengers in order for an airplane to fly it and over two times
the speed of sound there really has to be shaped kind of like a rifle bullet
long and slender the nose has to be pointed the tail has to be pointed to
allow that the air to come back smoothly together after the airplane parts it in
supersonic flight that’s not very structurally efficient
shape one of the difficulties with Concorde is that the long pointed nose
severely limits the pilots vision on takeoff and landing the Concorde has a
nose that actually droops down so that the pilot can see the runway all the
mechanical widget Ori required to drop that nose probably weighs 5 or 10,000
pounds if we on the other hand can develop an airliner which doesn’t
require the nose to drop down then we can save 5 10,000 pounds and make the
airplane much more the challenge in having a fixed nose
type of aircraft is that you know we’re asking the pilot to fly an
airplane with no windows to see out front just windows on the side in the HS
CT pilots will have to land the airliner without ever seeing the runway no other
aircraft has ever attempted this 300 lives will hang in the balance the
pilots will have to rely on a fail-safe system of video radar and infrared
cameras if you lose power what happens to that display
what are your backup systems how is the pilot going to respond in a failure mode
situation to test the feasibility of windowless
cockpits an unusual experiment was carried out in a specially modified
Boeing 737 installed in the hold was a blind windowless cockpit directly
connected to the aircraft’s controls infrared cameras showed the pilots where
the runway was the test pilots attempt to land the 51
ton aircraft without ever seeing the right very gently
amazingly the tests prove that the advanced cameras and sensors could
provide even better images than the human eye after proving the viability of
windowless landings NASA test pilots were then able to fly the HS Ct years
before one could be built they programmed the flight
characteristics of the HSC tea into this simulator the biggest in the world the
seventy million dollar vertical motion simulator at NASA Langley motion ready over 120 feet high the vertical motion
simulator can precisely simulate the movement of any aircraft from a fighter
to a supersonic airliner this is the biggest theme park ride in
the world it is so loud its sound was used as the roar of t-rex in the film
Jurassic Park for a pilot it is an invaluable source of information on how
new aircraft will handle projects like this are funded by NASA because they
depend on so much basic research to go beyond this stage of development the HSC
T will need private investors if it is to turn into reality some estimate that
over 200 of these superfast airliners would be needed to satisfy the world’s
airlines the HSC T might one day be a common
sight in our skies but even this plane will have limitations on its speed
commercial supersonic aircraft all used relatively conventional turbine powered
jet engines that is their turbine based engines as we call them if we want to
fly much faster than say Mach three or three and a half we’re gonna have to go
to different kinds of jet engines the jet engine was first invented by England
Sir Frank Whittle in the 1940s every jet engine flying today still uses the same
principle even the biggest and most advanced jet engine in the world the
rolls-royce Trent 800 is little different it can generate one hundred
four thousand pounds of thrust and hurl the largest airliners through the skies
it is so robust it can even cope with 30,000 gallons of
water an hour in mid-flight without faltering
but even this ultimate jet engine needs air to burn its fuel it has an altitude
limit the x-15
is the fastest aircraft ever to fly in 1967 it flew at Mach 6.7 an incredible
4600 90 miles per hour and reached an altitude of over 60 miles the very edge
of space if an airliner could fly this high it would experience virtually zero
drag and be able to fly from Los Angeles to Sydney in less than an hour but it’s
jet engines cannot operate this high as there is no oxygen to feed them the x-15
was propelled by a rocket engine it didn’t need oxygen to burn its fuel even
the Space Shuttle needs to carry more than its own body weight in fuel to
reach the edge of the atmosphere the shuffle orbiter weighs a mere 77
tons but it has to carry 1785 tonnes of fuel to liftoff if we want to build airliners that can
travel as fast as the x-15 or the shuffle we will have to develop a
completely new type of aircraft one that flies in and out of space this new design will take off like a
plane but fly like a spaceship an exciting new aircraft only possible
because of a new type of propulsion it’s a new concept in propulsion systems and
therefore it’s it’s really a concept of propulsion systems that can enable new
classes of vehicles completely unlike vehicles that we see today right now Tom Harsha and the rest of the
NASA Boeing team are developing an air-breathing rocket engine prototype
called HyperX it will be so powerful that it will shatter all previous speed
and altitude limits just 12 feet long the unpiloted prototype will be carried
to 100,000 feet by a pegasus booster rocket used for launching satellites it will be released and it’s
experimental engines ignited HyperX will use its unusual curved shape
to scoop oxygen from the thin air and ram it at high pressure into its
combustion chamber mixed with explosive hydrogen it will propel the craft
forward in an unbelievable two miles per second the test will last only seven
seconds the kind of range that the vehicle
designed that HyperX represents scaled up to a reasonable sized vehicle is ten
thousand miles with a two hour endurance you’re looking at a fourteen thousand
mile flight which is about halfway around the world white sands missile base New Mexico here
tests are taking place on what might be the single biggest revolution in
propulsion ever visionary designer professor Lake Mirabeau is developing a
saucer-shaped aircraft that flies on a beam of laser light a full-sized vehicle
of this design might one day carry people around the world or into space
its power supply and engine remain on the ground light craft is a completely
new flight transportation concept you have to imagine highways of light that
vehicles would ride upon you don’t need turbines compressors
combustors you don’t need that technology on these vehicles the work is
done for you by the light this light is a remnant of Cold War weapons technology
housed in this building is the control center of a powerful laser gun that
shoots the small craft into the sky okay copy the Plymouth’s laser is go for a
graphite run stand by before each flight the laser is tested for intensity on a
solid block of graphite four three two one firing this highly polished cone
focuses the laser beam vaporizing the air around it this is
then mounted beneath a nose cone the craft is simple it has no moving parts
no engine focusing the laser beam at the bottom of
the craft creates a series of explosions that push the craft skyward
but when professor Maribel first proposed this amazing new concept no one
believed it was possible there really wasn’t anybody in the academic
institution that I was going to that was willing to sponsor this kind of research
so I really I had to to get into this from the back door by actually
participating in the Star Wars business in 1997 NASA financed the idea early
tests were held indoors but after just a few months it was flying higher than the
roof of the lab and had to be moved outdoors horizontal wire tests were used
to see how far the laser could propel it then it was time for the laser light
crafts first free flight professor Mirabeau makes it spin at up
to 6,000 revolutions per minute with compressed air to keep the lightweight
model balanced during its flight at this speed like a spinning top it stays
perfectly centered in the beam until it runs out of power and falls back to
earth the laser-light craft is now flying
higher and further each day 10 seconds the club its lasers arming five four
three two one as the model lifts off the square-shaped
laser beam is focused to maintain its power and effectiveness but the 10,000 watt laser beam could
destroy the laser craft if it fails the next step is that we have to build a 100
kilowatt laser and with that laser we’ll be able to fly vertically to the edge of
space say 30 kilometers straight up professor Mirabeau is already conducting
indoor tests on this much larger design in a few years this laser craft could
deliver a small satellite into orbit and in 50 years time the laser light crafts
descendants might even be as common as the family car you’ll walk out your door
touch your magnetic levitation belt and float up you know to the vehicle it’ll
fly around pick up a couple of your friends motor over to a microwave laser
Bou station in ten seconds here at the top of the atmosphere leaving an escape
velocity for the moon at nighttime while you’ll see this is extremely bright
flash of light leaving the planet and people say well there goes Frank in the future the only limit will be the
designers imagination I think history shows that there has never been limits
that lasts very long now right now there are even some people that say that the
speed of light is not a limit which we believe it is today it probably isn’t the technologies that will make these
amazing vehicles possible are already available we’ve really begun just to scratch the
surface of what we really can do in aviation and I see many many changes
coming about during the next few years based on technology that we already
understand all around the world new developments are taking place in
propulsion avionics and aerodynamics developments that will take us far
beyond the limits of conventional aircraft developments that will make the simple
winged aircraft a thing of the past and change the way we fly forever
