AI Technical Summary
The stability and maneuverability of wide-speed-range aircraft vary in complex ways, and existing technologies lack research on the controllability of control surfaces across the entire flight profile, which increases the design difficulty.
This paper provides a method and system for assessing the controllability of a wide-speed-range aircraft. By evaluating the controllability of tasks such as longitudinal attitude trim, sideslip trim, maneuver overload, high angle of attack pitch, roll yaw inertial coupling, rapid roll maneuver, and coordinated maneuver, the system identifies the tasks with the highest control surface effectiveness requirements and the maximum required rudder deflection, thus guiding control surface design and flight control.
It effectively guides the design of aircraft control surfaces and flight control, ensuring that aircraft maintain stability and maneuverability in different flight missions, and improving the effectiveness of flight control systems.
