Device for detecting wind resistance of fixed-wing aircraft

Abstract

The invention relates to the technical field of fixed-wing aircraft detection, in particular to a fixed-wing aircraft wind resistance detection device which comprises a blowing mechanism, a base, a fixing mechanism and a detection mechanism, the blowing mechanism comprises a supporting plate fixed to one side of the outer wall of the top of the base, and a circular groove is formed in the outer wall of one side of the supporting plate; the air blowing mechanism, the fixing mechanism and the detection mechanism are located above the base, the fixing mechanism is arranged, the distance between the two fixing frames is adjusted according to the width of an aircraft wing, then the fixing frames are fixed to the mounting columns through locking bolts, the test height of the aircraft wing can be adjusted, and the test accuracy is improved. The first hand wheel on the fixing frame is rotated to drive the sliding blocks on the two-way lead screw to get close to each other, so that the fixing blocks extrude and fix the aircraft wing, the supporting springs and the extrusion convex blocks on the fixing blocks can increase the friction force between the fixing blocks and the aircraft wing, and the fixing stability is improved.

Description

technical field [0001] The invention relates to the technical field of fixed-wing aircraft detection, in particular to a wind resistance performance detection device of a fixed-wing aircraft. Background technique [0002] Fixed-wing aircraft, also known as fixed-wing UAV, is a fixed-wing micro-UAV. It is widely used because of its low noise and good concealment. However, fixed-wing UAVs also have some problems. For example, the endurance capacity is poor, etc. After the production and processing of the fixed-wing aircraft is completed, its wind resistance performance needs to be tested. During the wind resistance performance test and detection process of the fixed-wing aircraft, the fixed-wing aircraft needs to be fixed. The way of fixing the fixed-wing aircraft on the wind resistance performance detection device of the wing aircraft is to fix it through the support rod. [0003] Publication No. CN113532790A China Invention discloses a wind resistance performance detection ...

AI Technical Summary

Problems solved by technology

[0004] But above-mentioned patent has following deficiency, can not change wind direction, thereby has reduced the detection range to aircraft wing, and the fixing method of above-mentioned patent is single, can't simulate and detect the wind resistance performance of wing of aircraft, use has limitation, therefore urgently Need a kind of fixed-wing aircraft wind resistance performance detection device to solve the above problems
