Abstract

The invention relates to a three-degree-of-freedom model support mechanism of a high-speed wind tunnel, which belongs to the field of aviation aerodynamic wind tunnel support tests. Including base, support column, yaw platform, first driving device, first locking device, pitch platform, second driving device, second locking device, model, model installation platform, third driving device and third locking device device, the supporting column is connected with the base and the yaw platform, the first driving device is connected with the supporting column to drive it to do yaw movement, the second driving device is connected to the pitching platform to drive it to do pitching movement, the model installation platform and the model connection, the third driving device is used to drive the model installation platform to move axially, the first locking device is used to lock or release the yaw platform, the second locking device is used to lock or release the pitch platform, and the third lock The tightening device is used to lock or loosen the model mounting platform. Realize three-degree-of-freedom movement, with two working modes of fixed and variable attitude, which can make the aircraft model move centered.

Description

technical field [0001] The invention relates to the technical field of aerodynamic wind tunnel support tests, in particular to a three-degree-of-freedom model support mechanism in a high-speed wind tunnel. Background technique [0002] In a high-speed wind tunnel, in order to simulate the impact of high-speed aircraft in the complex flow field, the three-degree-of-freedom model support mechanism not only needs to support the model of the test section, but also adjust the pose of the model in the test section. At present, the three degrees of freedom changes realized by most three-degree-of-freedom mechanisms are angle changes in the angle of attack, position changes in the vertical direction, and position changes in the horizontal direction. [0003] In the design of a wind tunnel, the three-degree-of-freedom changes realized by the three-degree-of-freedom model support mechanism are pitch angle changes, yaw angle changes, and axial position changes. The test model realizes...
