No, you're talking about flight control authority and dynamic stability of the aorcraft while in hover while I'm talking about the potential possibility of loss of control/stability, eg stall caused by hot gas ingestion. Like I've said, I don't think we're talking about something that contradicts the other. Maybe it was my wording and I should've said "dependancy" rather than "stability".


SDLF with its jet of cold air screens the hot gas more effectively than the jst screen on X-32 ever did, combined with the fact that the intake is more spaced from the exhaust. Also like I've said, ACS design of X-32 is quite a bit more complicated than that of X-35/F-35B. Also, I don't disagree with what you're saying.


I'll try to find the AIAA course that you've mentioned. Thank you for the information. A refommendation from my side would be NASA's research and evaluation regarding STOVL concepts from the 90s and early 2000s. They were specifically evaluating concepts outlined for the ASTOVL program. Their evaluation, although preliminary at the time, also pointed out that a mixed flow exhaust through main nozzel during wing-borne flight and a lift mechanism separate from the main engine exhaust while jet-borne flight was the most suitable.
