Abstract:
A typical wing-aileron combination is taken and ternary flutter calculations between wing bending, wing torsion and aileron rotation are described. The results are plotted as graphs of flutter speed against aileron frequency and the effects of changes in aerodynamic derivatives such as might occur at transonic speeds are investigated. The derivative changes are (1) reduction first in (-hβ) and then in all β derivatives and (2) aft shift of wing aerodynamic centre and aileron aerodynamic centre, separately and together.
