AIRCRAFT ELEVON CONTROL MECHANISM Russian patent published in 2022 - IPC B64C9/00 

FIELD: rocketry.

SUBSTANCE: invention relates to the field of rocketry and relates to controlled aerodynamic surfaces and their control mechanisms. The aircraft elevon control mechanism consists of a rotation shaft located in the aircraft body, a lever rigidly fixed on the shaft, and a steering machine installed in the aircraft body. The rod of the steering machine is pivotally connected to the lever. One end of the shaft is connected to the elevon, which is pivotally mounted on the trailing edge of the wing. The other end of the shaft is connected to a spherical support installed in the body of the aircraft, and contains a bushing, in the central part of which a lever is rigidly fixed. One side of the sleeve is pivotally connected to the spherical support, and the other side contains a longitudinal groove. The end of the shaft connected to the elevon is made in the form of a kinematic chain, which consists of an output shaft. One end of the output shaft contains a tip rigidly fixed in the elevon. The central part of the shaft contains a cylinder. One end of the cylinder is connected to the output shaft through a cardan joint. The other end of the cylinder contains a key and is telescopically connected to the sleeve with the possibility of longitudinal movement. In this case, the key is placed in the longitudinal groove of the bushing.

EFFECT: proposed technical solution made it possible to implement the control mechanism for the elevon located on the trailing edge of the wing, regardless of the temperature deformations of the control mechanism and aircraft components during their operation and technological errors in the manufacture of parts of the mechanism and its installation on the aircraft.
