I do not understand how the Gross Thrust aka m dot * Ve can be constant, the Ram drag aka m dot * Va can be linearly increasing, and the Momentum Thrust be constant. Wouldn't the Momentum Thrust decrease if Va is increasing while Ve is remaining constant?

how could this be lecture three

Graphs are wrong …..Gross thrust

How NPTEL makes such boring lectures compared to open MIT courses….
