Abstract

The invention provides a forked space rod-type parachute wind tunnel test supporting device which comprises a wind tunnel connecting component, a front supporting component, a rear supporting component, a front balance connecting component and a rear balance connecting component. The wind tunnel connecting component is fixed onto the wall of a wind tunnel, the front supporting component and the rear supporting component are of rod-shaped structures, one end of the front supporting component is fixed onto the wind tunnel connecting component, the front balance connecting component is fixedly arranged at the other end of the front supporting component, one end of the rear supporting component is fixed onto the wind tunnel connecting component, the rear balance connecting component is fixedly arranged at the other end of the rear supporting component, and an included angle is formed between the front supporting component and the rear supporting component and larger than 90 degrees and smaller than 180 degrees. The forked space rod-type parachute wind tunnel test supporting device is simple in structural form and low in manufacturing process difficulty, a supporting fixture is provided for parachute wind tunnel tests, high-quality completion of the parachute wind tunnel tests is ensured, and the problem of supporting difficulty of the parachute wind tunnel tests is solved.

Description

technical field [0001] The invention relates to the field of wind tunnel test devices, in particular to a bifurcated space rod type parachute wind tunnel test support device. Background technique [0002] As a high-efficiency deceleration structure, parachute is widely used in fighter jets, returnable spacecraft and lunar probes. With the rapid development of my country's aerospace technology, it is necessary to design a new type of parachute to meet the demand. Therefore, obtaining accurate parachute aerodynamic parameters is extremely important for the design of fighter jets, returnable spacecraft, lunar probes, etc. The wind tunnel test of a parachute is an effective means to obtain its aerodynamic parameters, and the supporting device of the parachute wind tunnel test is a prerequisite for the parachute wind tunnel test. At present, there is no public document about the support device for the bifurcated space pole parachute wind tunnel test. Contents of the invention ...
