Telescopic canard rudder mechanism

Abstract

The invention provides a telescopic canard rudder mechanism, which comprises a mounting bracket, a telescopic device, a deflection device and a canard rudder surface, and is characterized in that a first mounting bracket and a second mounting bracket are fixed on the mounting bracket; the telescopic device comprises a push rod and a first driving assembly used for driving the push rod to do telescopic motion, the push rod and the first driving assembly are both installed on the first installation support, the push rod is in sliding fit with the first installation support, and the end, away from the first installation support, of the push rod is fixedly connected with the duck rudder surface. The deflection device comprises a deflection shaft sleeve and a second driving assembly used for driving the deflection shaft sleeve to rotate, the deflection shaft sleeve and the second driving assembly are both installed on the second installation support, the deflection shaft sleeve is in rotary sliding fit with the second installation support, and the end, away from the second installation support, of the deflection shaft sleeve is fixedly connected with the canard control surface. The canard rudder can extend out of the aircraft or retract into the aircraft according to needs and can deflect according to needs, and the control precision of the flight path of the aircraft can be improved.

Description

technical field [0001] The invention relates to the technical field of aircraft structure design, in particular to a retractable canard mechanism. Background technique [0002] In the technical field of aircraft engine structure design, the canard is the key component for generating aircraft control force. There are also certain applications in the structural design of the telescopic structure aircraft. Existing telescopic mechanisms are generally used for airfoils, etc., to control the one-dimensional rotation or movement of the airfoils. [0003] With the increasingly prominent demands of multi-tasking, the conventional variable-surface aircraft cannot meet the actual requirements of precise control of the flight trajectory, and a canard telescopic mechanism is required to realize the adjustable output of the control force. At present, the aircraft controlled by the canard in active service mainly use the wall of the launch tube as the initial restraint mechanism of the ...
