METHOD OF CONTROLLING AIRCRAFT STABILITY IN FLIGHT AND DEVICE TO THIS END Russian patent published in 2009 - IPC B64C13/00 B64C5/06 B64C9/00 

FIELD: transport, aviation.

SUBSTANCE: proposed device comprises control surfaces (1, 4) deflected by hydraulic cylinders (9) and arranged on outer (2, 3) and inner (5, 6) sides of the L.H. and R.H. fins, and additional control surfaces (7, 8) arranged on upper surfaces of the aircraft L.H and R.H. outer wings deflected by hydraulic cylinders (10). The device comprises also the transducers allowing for the following parameters, i.e. Mach number (M), gliding angle (β), angle of attack (α), barometric pressure at an altitude. The proposed device incorporates also automatic control unit and solenoid valves to control hydraulic liquid supply into hydraulic cylinders.

EFFECT: control over direct and transverse stability of aircraft by means of additional control surfaces.
