Abstract:
This paper presents an investigation into the controllability for an aircraft of
seamless aeroelastic wing. The research is aimed at the design of control laws
for the aircraft rolling by actively operating a pair of an unconventional
hingeless flexible leading and trailing control surfaces at different flight
speed. The main challenge is how to achieve a specified rolling rate for the
aircraft when the control effectiveness drops down and even crosses over the
rolling reversal point within the flight envelope. This phenomenon is mainly due
to the aeroelastic effect of the large sweptback and highly flexible wing design
for weight saving. The investigation shows that control laws varying with the
flight speed can be designed to achieve the rolling control target.
