FIELD: aviation.
SUBSTANCE: invention relates to all-moving aircraft (AC) rudders. Aerodynamic rudder of high-speed aircraft (HAC) consists of a cantilever mounted on the axis of rotation, and is equipped with two flaps located on the right and left relative to the cantilever. Flaps are fixed with possibility of dense atmospheric layers separation at achievement of HAC. Said flaps are rigidly interconnected by bolt and pivotally connected along rudder rear edge. Between the flaps there is a flap release and repulsion mechanism (FRRM) made in the form of a screw-nut pair. Upper part of the screw is sharpened with the possibility of cutting the bolt connecting the flaps. On cantilever housing there are slots, and on flaps corresponding to them ledges for retaining flaps on cantilever. Inside the axis of rotation of the console there is a hole for mounting the screw FRRM. In the hole located inside the cantilever of rotation there installed is a stock of pyro cartridge for separation of the flaps. Pyropartron is located inside HAC.
EFFECT: invention is aimed at reducing the area of aerodynamic rudder at increasing high-speed pressure head.
