ABSTRACT = {The static aeroelastic effect of aircraft ailerons with high aspect ratio at transonic velocity is investigated in this paper
by the CFD/CSD fluid-structure coupling numerical simulation. The influences of wing static aeroelasticity and
the ‘scissor opening’ gap width between aileron control surface and the main wing surface on aileron efficiency are
mainly explored. The main purpose of this paper is to provide technical support for the wind tunnel experimental
model of aileron static aeroelasticity. The results indicate that the flight dynamic pressure has a great influence
on the static aeroelastic effect of ailerons, and the greater the dynamic pressure, the lower the aileron efficiency.
Aileron deflection causes asymmetric elastic deformation of the main wing surfaces of the left and right wings. The
torque difference caused by the load distribution on the main wing surface offsets the rolling torque generated by
the aileron. This results in a significant reduction in aileron efficiency, and it is noticeable that it is not the elastic
deformation of the aileron itself or the reduction in effective deflection that leads to the reduction in rolling control
efficiency. Under typical transonic conditions, the rolling control torque of the aileron can be reduced by more than
25%, in the range of 2.5–10 mm, and the ‘scissor opening’ gap width of the aileron has almost no influence on its
static aeroelastic effect.},
