Abstract

The invention relates to a forced yawing-free rolling wind tunnel test device, which can realize forced yawing-free rolling wind tunnel test of an aircraft model more conveniently and effectively. The invention adopts the technical scheme that: the forced yawing-free rolling wind tunnel test device is arranged on a device seat [1], a motor [2] drives a decelerator [3] and a web support vertical shaft [4] to drive a free rolling part, and an aircraft model [10] is connected with a web support-variable tail support strut [5] through bearings [6] and [9] and connected with a rotary encoder [7] through a coupling [8]. The device can realize forced yawing motion, free rolling motion and forced yawing-free rolling motion of the aircraft model, and can perform forced yawing-free rolling time history measurement.

Description

1. Technical field [0001] The invention relates to a forced yaw-free roll wind tunnel test device, which is mainly used for the forced yaw-free roll test in the wind tunnel test of tail brace and belly brace models. 2. Background technology [0002] In the wind tunnel test of the simulated aircraft, it is necessary to simulate the forced yaw-free roll motion of the aircraft model and measure the angle time history, which requires corresponding test equipment to meet the forced yaw-free rolling motion of the simulated aircraft. Wind tunnel test requirements for rolling motion. In the prior art, there is a lack of forced yaw-free roll wind tunnel test devices. 3. Contents of the invention [0003] The purpose of the present invention is to provide a forced yaw-free roll wind tunnel test device, which can realize the forced yaw-free roll motion simulation of the aircraft model more conveniently and effectively, and can measure the angle time history. [0004] The technical ...
