Problems solved by technology

In most cases, either the aileron angle adjustment and locking devices are installed on the surface of the aircraft model for testing, resulting in "distortion" of the ground simulation test; Important aerodynamic parameters in the state of angle change
These "inadequate" wind tunnel tests have brought greater safety hazards to aircraft design

Abstract

The invention discloses a wind tunnel aircraft model aileron angle adjusting device which comprises an aircraft model body, one end of the aircraft model body is connected with a model supporting rod,ailerons are rotatably connected to the aircraft model body, and angle adjusting mechanisms used for changing the angles of the ailerons and fixing the ailerons are symmetrically arranged in the aircraft model body. The wind tunnel aircraft model aileron angle adjusting device has the advantages that the aileron can deflect at different angles, the adjustment is simple, the operation is convenient, the aerodynamic configuration of the aircraft model is not changed, and the quality of a wind tunnel test flow field is not influenced.

Description

technical field [0001] The invention belongs to the technical field of wind tunnel test devices, in particular to a wind tunnel aircraft model aileron angle adjustment device. Background technique [0002] During the wind tunnel test, it is sometimes necessary to adjust the aileron angle of the aircraft model to obtain different aerodynamic parameters. However, it has always been difficult to adjust and lock the aircraft model ailerons: First, the wind tunnel aircraft model is designed and manufactured according to certain scaling and flow field blockage requirements, and is generally relatively small and fine, especially for hypersonic and thin transitional flow Under the conditions of the simulation test in the regional area, the aircraft model is smaller, and it is difficult to install the aileron angle adjustment and locking device on the small model; second, in the ground test of the aircraft, in order to simulate the high-altitude dynamic environment of the aircraft as...
