I have this picture, of McDonnell-Douglas' Model 265, which is labelled "AFTI". Did McDonnell-Douglas submit Model 265 to the AFTI program?
This was a transonic demonstrator aircraft proposed to demonstrate the basic principles of the vectored incidence wing with the fuselage beavertail control surface for trim. the fundamental concept was that the fuselage could be aimed about plus or minus 15 degrees without changing the flight path angle or the fuselage could remain on track while the wings angle of attack was increased to maintain track. The real sticking point came in ground attack when the flight path was level and the nose pitched down to maintain track on the target. Pilots have only the fuselage angle to estimate flight path so they IMMEDIATELY broke of the attack as they assumed they were flying at the ground not level. There were full scale operationally sized supersonic configurations as well as transonic concepts. It was a really unique concept that went against all of the status quo thinkers and macho pilots who did not need automatics.overscan said:Pictures from Ebay added. Project was also called VLF - Vectored Lift Fighter.
A German team headed by Wolfgang Herbst was hired to assist in a STOL fighter competition that stayed on to develop the CADE Computer Aided Design Evaluation concept. Wolfgang was a close in maneuvering combat advocate with high angle of attack, thrust supported, off angle shots. When the team returned to Germany he concentrated on high angle of attack, slow maneuvering combat. On result was the Rockwell X-31 and the configuration of the Eurofighter. To my knowledge he never advocated the VLF conceptoverscan said:It is now confirmed that the Model 265 (Vectored Lift Fighter) formed part of the agile fighter joint studies between McDonnell-Douglas and MBB. Around 1978, the two companies worked together on new fighter technologies for AFTI and TKF-90 respectively and a report was produced that year which examined the McDD VLF and the early MBB TKF-90 canard delta configuration with a view to producing a demonstrator - either a 19,000lb design with twin F404 or RB.199 engines or a 12,000lb design with twin J85s. Both the MBB and McDD designs are fitted with 3d thrust vectoring nozzles.
Most of these isometric renderings were hand drawn by a single individual with an uncanny skill to look at a 3-view and sketch the result free hand. He unfortunately had a problem that after a long number of years made his employment difficult and so there was no one ever to replace him except unemotional computer graphics.Archibald said:The Douglas 265 has become symbol of this forum. who make the 3-d rendering of this lovely project ?

Getting back to AFTI, where can I find more info on the McDonnell-Douglas Model 265. I did a search and just came back to this thread (probably doing it wrong). It looks pretty but I don't understand it at all. I read somewhere it was a VSTOL project, how did that work? And what's with the lack of tail surfaces? I know it's got those little chin fins (like the F-16A AFTI) and a sort of beaver tail but doesn't look like an improvement to me, especially if it had an all moving wing like the similar Rockwell concept. Does the '265' have an all moving wing too? etc, etc.
