golfsierra2 Posted June 11, 2011 Posted June 11, 2011 Is this the real max movement of the empennage ? This must make the aircaft extremely manoeuvrable... I never saw this rudder output on a westen plane. Imagine how this plane reacts once airborne... Source: http://www.ausairpower.net/APA-J-XX-Prototype.html kind regards, Raven....

Vekkinho Posted June 11, 2011 Posted June 11, 2011 Well it depends, I hardly believe this deflection is possible during flight as it would probably cause more drag than action. This pic is probably taken with engines off so you can't expect any hydro pressure or it's only possible for steering during taxi. Even if it's possible, J-20 would lose a lot of speed and reduce her maneuverability... Just my 2 cents! [sIGPIC][/sIGPIC]
mikoyan Posted June 12, 2011 Posted June 12, 2011 I guess you never saw the f-22 with the engines off or the superhornet.
Avilator Posted June 12, 2011 Posted June 12, 2011 The engines are running in the picture. The airplane is turning around on the taxiway. My guess is that as the airspeed increases the flight control computer allows a smaller deflection angle. EDIT: Are they used as airbrakes?

Viper101 Posted June 12, 2011 Posted June 12, 2011 Those pictures make the J-20 look like a concept of a jet straight out of a comic book or cartoon series. What are they expecting it to be able to do, tumble around in the sky and do a triple back-flip or twist?:megalol: [sIGPIC][/sIGPIC]
