Optimization of Control Surfaces Using Different Corrugated

WebControl surface flutter typically involves wing torsion and control surface rotation. The flutter speed may be raised by an increase in the control circuit stiffness (to increase the control frequency) or by mass-balancing the control surface (to eliminate or reduce inertia coupling). It is also possible for tab flutter to occur. WebResults of a supersonic flutter investigation of three low-aspect- ratio control surfaces are presented in this paper.
