Abstract

The invention relates to the technical field of hypersonic wind tunnel tests and particularly discloses a hypersonic wind tunnel head-body separation jet interference test device. The device includesa model posture adjustment device, an inter-stage distance adjustment device, a jet connection device and a sliding bottom cover, wherein the model posture adjustment device, the inter-stage distanceadjustment device and the jet connection device are connected in turn, and the sliding bottom cover sleeves the inter-stage distance adjustment device. The model posture adjustment device is arrangedinside a secondary model, and the model posture adjustment device adjusts the positive and negative angles of attack of the secondary model in the up and down directions and the angles of sideslip ofthe secondary model in the left and right directions, and the inter-stage distance adjustment device can adjust changes of the relative positions of a primary model and the secondary model. The devicereduces the processing cost, the labour intensity and the difficulty to change the state of a test model, improves the test efficiency, avoids the problems of angle errors, inter-stage distance deviation and repeatability caused by processing and installation errors.

Description

technical field [0001] The invention belongs to the technical field of hypersonic wind tunnel tests, and in particular relates to a jet interference test device for head-body separation in a hypersonic wind tunnel. Background technique [0002] At present, the state of the conventional hypersonic wind tunnel model is complex, and the attitude of the model changes frequently. For the inter-stage separation jet interference test, there may be a large number of arbitrary combinations of relative angle of attack and relative sideslip angle adjustment states in the first-level and second-level models. However, the angle-of-attack mechanism cannot realize the relative attitude adjustment of the two-stage model. At present, the adjustment of the primary and secondary relative attitudes is achieved by processing different transfer rods. The number of processed transfer rods is large and the model structure is complex. Conventional transformation of attitude angle and step spacing a...
