Abstract:

Post stall maneuvers were optimized with a mission c overage of flight path reorientation and target pointing. Numerical practice has shown that for a rapid flight path reorientation the flight should be at the maximal lift angles of attack and close to the corner velocity while the maximum throttle setting be favorable due to the large deceleration, which is clearly illustrated by turn rate plots too. On the other hand, the first segment of a rapid target pointing requires a rapid flight path reorientation, and then in a proper position super high angles of attack are employed for pointing. Flight simulations give the operational process of the maneuvers by aircraft with control services and a flight control system suited for the post stall regime. Maneuvering at an extremely low speed, however, could exceed the controllability of the even control-enhanced aircraft.
