Cranfield is the only university in the world with its own airport, airline status its own aircraft, its own pilots and crucially its own air
traffic control and navigation services. services we have a huge team that is very involved in aircraft vehicle design so designing aerospace vehicles of the future. So we have this wonderful array of facilities that are relevant to aerospace of the future And the aerospace is at a really interesting
juncture in its development. There are a lot of exciting things happening in the aviation industry, we see on one side that there’s a major growth in air travel demand which needs to be responded by the aviation industry one side but on the other side we also
need to make air travel sustainable. We will need to reduce the ecological
footprint of the aviation industry drastically. The industry will have to innovate a lot in order to reach the targets that have been set by flight path 2050 and by ACARE. So, as the aerospace industry looks to the future it is looking at all the ways of actually reducing emissions so it needs to make sure that its existing propulsion methods gas turbines and so on, operate as efficiently as possible but with as low emissions as possible and it then also needs to look to future methods of propulsion so that it can also understand those, bring them on stream as effectively as possible where they do contribute to the reduction in emissions. For hybrid electrical propulsion units it’s very important to understand how the gas turbine connects to the electrical generator how it connects to the electrical power distribution system, the battery system, and the electrical propulsion unit that drive the propellers or the fans. So in order to create that integrated view of the behavior of the aircraft during its mission, we developed already since 8 years a solution package called the virtual integrated aircraft capabilities that make it possible to basically model each individual system separately like the environmental control system the pneumatic system, ice protection system hydraulic system etc. But on the other side we have also made sure that all these different systems can connect to each other to a virtual integrated aircraft. We at Siemens we have been developing within Simcenter Amesim, different libraries that basically address all different power systems of the aircraft. We have been creating specific libraries for the environmental control systems, for the landing gear, for the hydraulic systems and we have right now also developed specific libraries for hybrid electrical propulsion units. In that context we work together with Cranfield University to make sure that the gas turbine component of our libraries are basically developed in the right way that they are addressing the right physics, that are specifically needed for hybrid electrical propulsion. Cranfield is working in collaboration with Siemens Digital Industry Software on the Simcenter Amesim software. We are supporting the Siemens modeling capability we’re bringing expertise in models in demonstrations and expertise around the tools that actually support that modeling capability. Cranfield University also has a lot of expertise a lot of experimental data to validate the basic assumptions of the different elements in the gas turbine
library of Simcenter Amesim. The partnership started about two years ago and has now produced outcomes which are an integral part of the software. Partnerships with the academic world are very important to Siemens because they allow us to bring certain new products faster to the market. The academic world helps us to develop new methods, new ways to calculate the physics of certain aircraft components but on the other side the academic world has also a lot of experimental data that allows to basically bring in that credibility that allows to create a lot of validation data and doing that validation data to our customers when they integrate these libraries here specifically hybrid electrical propulsion unit libraries in context of their aircraft. Cranfield is at the heart of the aerospace of the future including the digital aviation agenda and our collaboration with Siemens Digital
Industry Software we see as very positive in that context. Cranfield University also worked on different application cases that we included in our online help and that can be used by our customers as some kind of kickstart model in context of hybrid electrical propulsion. So, Cranfield University basically helped us to make these libraries ready for the industry from the start.
