DEVICE FOR ENHANCING CONTROLLABILITY AND STABILITY OF WINGED AND FINNED FLYING VEHICLES AT HIGH FLYING SPEED Russian patent published in 2006 - IPC B64C9/12 B64C13/04 

FIELD: control of flying vehicles by means of aerodynamic surfaces.

SUBSTANCE: proposed device is provided with additional extended aerodynamic surfaces mounted on tips of wing or fin far away from their elastic axes. Each such surface is kinematically linked with control surface or aileron and is deflected through definite angle depending on velocity head, Mach number and deflection angle of control surface or aileron. This deflection forms the moment compensating for disturbance arising due to structural flexibility of flying vehicle. Extended surfaces are small (8 to 15% of aileron area) and are deflected through angles as large as possible. Adjustment of deflection angles of extended control surface and aileron is performed automatically of manually.

EFFECT: elimination of adverse effect of structural flexibility on controllability and stability of flying vehicle; possibility of using structural flexibility for enhancing these characteristics.
