Delta canards (au bout du nez). Herbst, de chez MBB (->TKF90...). http://oea.larc.nasa.gov/PAIS/Partners/X_31.html [quote]In West Germany, [b]Dr. Wolfgang Herbst[/b] of Messerschmitt-Bolkow-Blohm (MBB) [b]aggressively touted the advantages of post-stall technology (PST)[/b] for increased effectiveness during close-in air combat. [b]Herbst’s conclusions were based on wind-tunnel tests of a German advanced canard fighter configuration known as the [size=150]TKF-90[/size][/b] and piloted simulator studies during which the application of simulated thrust vectoring resulted in rapid directional turns at high angles of attack had increased the turn rate by over 30 percent. Technical discussions between the Rockwell SNAKE Program managers and Herbst were initiated in 1983, and planning for a mutual program on PST ensued. Discussions with the Defense Advanced Research Projects Agency (DARPA) were very positive. When funding for collaborative international activities became available from the U.S. (the Nunn-Quayle research and development initiative in 1986) and West German governments, the technical expertise of Rockwell and MBB were joined under DARPA sponsorship in [b]the X-31 Program.[/b] [/quote] Donc, maintenant, s'il y en a encore qui doute du lien de parenté entre l'Eurofighter, et le X-31, je distribue des baffes. :lol: http://www.airpower.at/flugzeuge/eurofighter/tkf90.jpg http://img523.imageshack.us/img523/9641/tfk4ql7.jpg Entrées d'air, delta, canards... http://www.btinternet.com/~david.Manley/wargames/instantthunder/eurofighter.jpg http://www.flug-revue.rotor.com/frtypen/Fotos/dasa/X-31Land.jpg Ca implique aussi que l'Eurofighter ne sera peut-être complet qu'avec les TVC. Autrement dit, pour l'instant, il serait inachevé.[/quote]
