Primary mirror adjusting and supporting system of large-diameter wind tunnel schlieren instrument

The invention discloses a large-diameter wind tunnel schlieren instrument primary mirror adjusting and supporting system which comprises a base, a U-shaped supporting frame body is slidably arranged on the base, a lifting tray is arranged in the U-shaped supporting frame body in a lifting mode, a U-shaped support is rotatably connected to the lifting tray, and the U-shaped support is rotatably connected to the base. A yaw adjusting mechanism is arranged between the U-shaped bracket and the lifting tray; a primary mirror bracket for mounting a primary mirror is hinged in the U-shaped bracket, and a pitching adjusting mechanism is arranged between the primary mirror bracket and the U-shaped bracket. According to the invention, while the primary mirror is stably supported, the multi-angle rapid adjustment of the primary mirror can be realized, and the beneficial effects of shortening the schlieren instrument adjustment time, saving human resources and improving the wind tunnel test efficiency are achieved. 本发明公开
