Light high-temperature-resistant control surface structure and canard rudder piece

Abstract

The invention provides a light high-temperature-resistant control surface structure and a canard rudder piece in the technical field of aircraft design. The light high-temperature-resistant control surface structure comprises a control surface mechanism and a dot matrix mechanism, and the dot matrix mechanism comprises a plurality of single-sided body cell elements. Each single-sided body cell element comprises a connecting rod and a plurality of combined frames. The single-sided body cell elements are mutually and fixedly arranged at an angle through the combined frames. Each combined frame comprises a plurality of combined rods, wherein the combined rods are mutually and fixedly arranged, and the end points of the combined rods are mutually fixed to form vertex angle connecting points. The single-sided body cell elements are fixedly arranged through vertex angle connecting points, and the dot matrix mechanism is connected and arranged in the control surface mechanism through the connecting rods. According to the light high-temperature-resistant control surface structure and the canard rudder piece, the requirements for vibration suppression, bearing and heat protection are met in a limited space, isotropy of structural rigidity is achieved, and the destructive effect of aerodynamic heat on the structure is reduced.

Description

technical field [0001] The invention relates to the technical field of aircraft design, in particular to a light-weight, high-temperature-resistant rudder surface structure and a duck rudder piece. Background technique [0002] In the field of aircraft design technology, canards are the key components for generating aircraft control force. At present, canards are often used in the initial stage of short-range missiles. With the improvement of the aircraft's maneuvering and overloading capacity requirements, it is necessary to pay a large overload in the middle or end of the trajectory, and the telescopic duck rudder provides a simple and feasible solution for this. However, the canard located at the front of the projectile is in the middle or end of the trajectory, and will suffer from severe aerodynamic noise and aerodynamic thermal environment. The conventional thin rudder surface structure is difficult to meet the working conditions. [0003] It is found through prior a...
