Embodiment Construction

[0029] In conjunction with the accompanying drawings, the following specific embodiments are given to further illustrate the technical solution of the present invention.

[0030] like figure 1 As shown, a hypersonic wind tunnel three-degree-of-freedom model delivery device includes an angle of attack change module, a vertical delivery module and a horizontal movement module.

[0031] like figure 1 and figure 2 As shown, the angle of attack change module is installed under the vertical delivery module, and is composed of machete 1, which can manually preset different attack angle values ​​of the model; the side of machete 1 is processed with multiple pairs of installation through holes according to the fixed center of rotation , the center connection line of the paired installation through holes passes through the center of rotation, and the angle between the center connection lines between two adjacent groups of installation through holes is 2°. When installing the model, t...

Abstract

The invention relates to a hypersonic wind tunnel three-degree-of-freedom model inputting device comprising an attack angle change module, a vertical inputting module and a horizontal moving module. The attack angle change module is a bent blade of which the side surface is provided with multiple groups of paired installing through holes according to a fixed rotating center, and one paired installing through holes are selected to install the model according to the requirements in testing. The horizontal moving module fixed in a wind tunnel top wall installing hole is provided with a model inputting hole. The vertical inputting module is installed on the horizontal moving module. The bent blade is installed below the vertical inputting module. The vertical inputting module can vertically input the bent blade provided with the model in the wind tunnel through the model inputting hole under driving of a high-speed hydraulic cylinder The model inputting device has three directions of degree of freedom and the structure is simple and compact so that the model inputting device is suitable for multiple size specifications of models and can meet the requirements of wind tunnel thermal measurement and other special tests requiring high-speed inputting.

Description

technical field [0001] The invention belongs to the field of aerodynamic wind tunnel tests, and in particular relates to a three-degree-of-freedom model delivery device for a hypersonic wind tunnel. Background technique [0002] In the hypersonic wind tunnel test, when performing special tests such as heat measurement on the model, in order to reduce the impact of the turbulent high-speed airflow on the test model and its supporting mechanism before the establishment of the wind tunnel flow field, and to wait for the airflow temperature and other parameters to reach For the required value of the test, it is necessary to place the test model outside the flow field in advance. After the flow field is stable and the temperature reaches the required value, the test model is quickly put into the flow field through the delivery device. [0003] In the design of a large-scale hypersonic wind tunnel, a model delivery device that meets the following requirements is needed: (1) It can...
