Flight Investigation of Lateral-Directional Flying Qualities and Control Power Requirements for STOL Landing Approach Using the X-22A Aircraft. Volume 1. Technical Results
Abstract
A flight investigation of the influence of lateral-directional dynamics and control power requirements on flying qualities for STOL aircraft in terminal area operations was conducted using the X-22A variable stability aircraft. The primary dynamic variables of the experiment were roll mode time constant, Dutch roll undamped natural frequency, roll-to-sideslip ratio, and yaw due to aileron; in addition, the roll control power available was varied by electrically limiting the lateral stick command of the evaluation pilot. Three pilots performed 102 evaluations of various combinations of these variables at a representative STOL approach condition of gamma = -7.5 degrees, V = 65 kts. During the evaluations, a qualitative separation of ambient turbulence level was made through approximate measurements from the aircraft.
