Technical Field

The invention relates to the technical field of aircraft design, in particular to a light high-temperature-resistant control surface structure and a duck rudder piece.

Background

In the technical field of aircraft design, a duck rudder is a key component for generating control force of an aircraft, and the duck rudder is commonly used in the initial stage of a short-range missile at present. Along with the increase of the maneuvering overload capacity requirement of the aircraft, the large overload is paid at the middle section or the tail section of the trajectory, and the telescopic duck rudder provides a simple and feasible solution for the purpose. However, the duck rudder in front of the projectile, in the middle or end of the trajectory, will be subjected to severe aerodynamic noise and aerodynamic heat. The conventional thin control surface structure is difficult to meet the use working condition.

The search of the prior art finds that the Chinese invention patent publication number is CN108824634B, and discloses a light space lattice structure, which comprises N single cells connected with each other; each unit cell comprises an upper polygonal frame a, a lower polygonal frame c and a side rod system b; the upper polygonal frame a and the lower polygonal frame b have the same structure, the side rod systems b are a plurality of connecting rods, and the upper polygonal frame a and the lower polygonal frame b are connected according to the same connecting principle, so that the structure is light. The invention, with the patent publication number of CN107100268B, discloses a light-weight spatial lattice structure, which is a spatial lattice material based on bent-rod cells, and includes N cells, each cell is formed by connecting two groups of bent rods through nodes in the cell, and each cell is connected through nodes between cells, and the cell is extended in the x, y, z directions to form a three-dimensional spatial lattice material. The curvature of each group of the bent rods in the cell elements is different, and the curvature of each group of the bent rods in each cell element adjacent to each other in the x, y and z directions is also different, so that the rigidity in different directions is changed according to the required gradient. However, the above-mentioned techniques have the following disadvantages: the difference between the heat-conducting performance of the internal air and the structure cannot be solved, and a large temperature gradient is often generated to cause structural damage.

Based on this, need to provide a light high temperature resistant rudder surface structure and duck rudder spare at present, need realize suppressing in the finite space and shake, bear and the demand of heat protection, realize structural rigidity's isotropy and reduce the destructive effect of aerodynamic heat to the structure.
