Wind tunnel angle-of-attack adjusting device

Abstract

The invention discloses a wind tunnel angle-of-attack adjusting device, which comprises an X-shaft mobile mechanism, a Y-shaft mobile mechanism, a yaw angle adjusting mechanism, and a pitch angle adjusting mechanism. By arranging the X-shaft mobile mechanism, the Y-shaft mobile mechanism, the yaw angle adjusting mechanism, and the pitch angle adjusting mechanism, the adjusting in four degrees of freedom is realized; and the pitch angle adjusting scope is greatly increased by loading a motor on a machete plate to revolute with a model pole in a limited test section space. The pitch angle adjusting scope is -10DEG-40 DEG, and is increased by nearly 10 DEG compared with that of a traditional way, therefore, the adjusting attitude of the angle-of-attack mechanism is added; the adjusting scope of the integral angle-of-attack mechanism is greatly increased; and the problems of small angle-of-attack scope of the wind tunnel angle-of-attack mechanism in a limited space and limited attitude adjusting scope of the angle-of-attack mechanism are solved.

Description

technical field [0001] The invention relates to the field of aerospace technology, in particular to a device for adjusting the angle of attack of a wind tunnel. Background technique [0002] At present, most of the existing wind tunnel angle-of-attack mechanisms have three degrees of freedom or less. In a limited space, the range of the angle of attack is narrow and the accuracy is relatively low. The attitude adjustment range of the angle-of-attack mechanism is limited. With the rapid development of my country's aerospace industry, an angle-of-attack mechanism suitable for large-scale wind tunnel tests, with a large variable range, many degrees of freedom, high precision levels, and a high structural strength and safety factor needs to be developed urgently. Contents of the invention [0003] The present application provides a device for adjusting the angle of attack of a wind tunnel, which solves the technical problems in the prior art that the angle of attack range of t...
