Abstract

The invention relates to a half-module pivoted window mechanism applied to a sub transonic speed wind tunnel. The half-module pivoted window mechanism comprises a driving transmission module, a feedback and measurement module and a rotating module, wherein the driving transmission module consists of a support seat, a large cylindrical straight gear, an alternating current servo motor, a speed reducer, a gear press cover, a small cylindrical straight gear, a compression cover and a compression screw, the feedback and measurement module consists of a potentiometer support seat, a potentiometer, a press sheet, a shaft coupler, a small shaft and a connecting cover, and the rotating module consists of a right bearing cover, a bearing seat, a pair of precise conical roller bearings, a left bearing cover and a main shaft. Through the adoption of a cylindrical straight gear group, the half-module pivoted window mechanism can realize the movement for positive 360 degrees and negative 360 degrees, in addition, the integral hosting of the mechanism can be realized, a measurement part adopting the potentiometer as the core is adopted for the transmission matching of the cylindrical straight gear group, and the attack angle control precision being +/-3' can be realized.

Description

technical field [0001] The invention relates to a half-mode turning window mechanism applied to a sub-transonic wind tunnel, belonging to the field of experimental aerodynamics. Background technique [0002] The half-model test technology is an important wind tunnel test technology, which can better solve the problem of low test Re number and difficulty in realizing the detailed simulation of aircraft shape due to the limitation of the section size of the test section when carrying out the full model test in the test section. And other issues. Most of the wind tunnels at home and abroad usually use the half-mold test system installed on the conventional test section for half-mold tests; some wind tunnels with larger diameters, such as CARDC2. A separately processed half-model test section is used, and the larger half-model is installed in the test section for aerodynamic tests. The swivel window mechanism is the core mechanism of the half-mold test system (or half-mold tes...
