Rotation adjustment mechanism and processing method, model attitude adjustment device and method

Abstract

The present invention discloses a rotation regulation mechanism and a processing method thereof, and a multi-degree-of-freedom model posture adjustment device and method. The rotation regulation mechanism comprises a tail brace rod, a brace face plate and a fixed seat. The rear end face of the brace face plate is provided with a plurality of grooves along the circumference, the front end face of the fixed seat is provided with bulging teeth cooperated with the grooves, or the rear end face of the brace face plate is provided with a plurality of bulging teeth along the circumference, and the front end face of the fixed seat is provided with grooves cooperated with the bulging teeth; a fixed model is assembled at the front end of the tail brace rod, the rear end of the tail brace rod penetrates the brace face plate and the fixed seat in order, and the fixed seat and the brace face plate are fixed at the rear end of the tail brace rod; and the included angle of axes of the front end and the rear end of the tail brace rod is the same as the angle of the required angle of attack. The rotation regulation mechanism is rotated in the fixed seat through the tail brace rod and regulates therotation angle to regulate the posture of the model at the front end of the tail brace rod and obtain flow field structure images of the model located at different measurement surfaces.

Description

technical field [0001] The invention relates to the field of aerospace technology, in particular to a rotation adjustment mechanism and a processing method, and a multi-degree-of-freedom model attitude adjustment device and method. Background technique [0002] The model attitude adjustment device adjusts the attitude of the model in the wind tunnel test through multiple adjustment mechanisms, such as horizontal displacement adjustment mechanism, vertical displacement adjustment mechanism, attack angle displacement adjustment mechanism, etc. Wind tunnel test is to study the aerodynamic performance of aircraft at large angle of attack important means. With the continuous development of aerospace technology, modern wind tunnels are also developing towards stronger test capabilities and higher production efficiency. It is required to simulate the test state of the model as much as possible, such as the pitch, yaw, and Rolling, horizontal translation, vertical translation and o...
