Abstract

The invention relates to a preparation method of a hollow grid structure wing rudder, belongs to the technical field of preparation of wing rudders, and solves the problems that a method for preparing a wing rudder in the prior art is complex in process and the prepared wing rudder is poor in performance. The preparation method comprises the following steps: a, according to the structure of the wing rudder, dividing the wing rudder into two parts which are symmetrical up and down along a chord plane, and designing an upper grid plate model and a lower grid plate model; b, preparing an upper grid plate and a lower grid plate according to the design model; and c, assembling the upper grid plate and the lower grid plate, and performing diffusion bonding. The method is simple in step and low in implementation difficulty, and the formed wing rudder is good in performance and high in precision.

Description

technical field

[0001] The invention relates to the technical field of wing rudder preparation, in particular to a preparation method of a hollow grid structure wing rudder. Background technique

[0002] With the development of aircraft towards high speed, long range, and strong penetration, it is more and more urgent to reduce the weight of its main structure. Lightweight structure is nothing more than the lightest material, the most optimized structure and the most simplified connection form. The weight of the material is determined by its own density. Under the premise of satisfying the service performance, low density is the basic principle of material selection. Among the existing metal lightweight structural materials, magnesium, aluminum, and titanium alloys are commonly used structural materials. The high temperature resistance of the material itself (≥ 500°C), only titanium alloys have high temperature resistance properties. Structural optimization is determined b...
