Abstract:
The compatibility between maneuver load control, relaxed static stability, and flying qualities requirements is investigated in the report. Three steps were involved in the investigation: an analysis was made of control surface combinations and their effectiveness for maneuver load control when used with an airplane having shortened tail length and reduced tail surface area, control system configurations were synthesized that minimize a weighted measure of change in drag, wing root bending moment, control surface activity and response error between a Level 1 flying qualities model and the actual T-33 airplane; and a direct optimization of the tail length, tail area and control surface deflections required to obtain a compatible compromise of the CCV objectives was performed.
