DETACHABLE AERODYNAMIC RUDDER OF HIGH-SPEED AIRCRAFT Russian patent published in 2021 - IPC B64C9/08 

FIELD: aircraft industry.

SUBSTANCE: invention relates to aerodynamic stabilization bodies for aircraft (AC), and more specifically to all-turning rudders. The separable aerodynamic rudder (AR) of a high-speed aircraft (HSA) contains a side panel fixed on the axis of rotation with the ability to detach when high-speed heads are reached. In this case, the line along which the AR is divided is chosen so that the center of pressure of the side panel of the AR, as well as the center of pressure of the entire AR, lies on the axis of rotation of the AR. In this case, the detachable panel is installed on the side panel using a spike connection and a locking device installed perpendicular to the separation line of the aerodynamic rudder, consisting of a pusher, a bolt with a tapered head, clamped by a split tapered sleeve in a cartridge, which is fixed in the initial position with a shear lock. In addition, a cylindrical channel is made coaxially inside the side panel of the AR and the fuselage of the HSA, in which a squib with a bullet is installed inside the fuselage of the HSA to influence the pusher of the locking device.

EFFECT: proposed technical solution makes it possible to reduce the area of the AR in flight and allows to solve the problem of controllability of the HAS with an increasing velocity head while maintaining small hinge moments of the rudder.
