Abstract

The invention relates to a nozzle storage and quick replacement device, which belongs to the technical field of experimental aerodynamics. The device mainly includes a wheel disc, a nozzle box, a reducer, a motor, a bracket, a pin shaft, a clamping mechanism and a center shaft. The bracket is placed on the ground, the central shaft is connected to the bracket through a rotating pair, the central shaft passes through the wheel disc, and is fixed with the wheel disc; the nozzle box is connected to the wheel disc through a pin shaft and the nozzle box can rotate around the pin shaft The clamping mechanism is placed on the ground to provide clamping force for the nozzle box; the motor is connected to the central shaft through the reducer, and the central shaft drives the wheel to rotate, and then drives the nozzle box to rotate along the axis of the central shaft. The invention creatively arranges the nozzle box around the central axis in the circumferential direction, and replaces the nozzle box by rotating to realize the rapid replacement of the nozzle box, which is easy to realize the automatic replacement of the nozzle box, improves production efficiency, and can save lateral space at the same time .

Description

technical field [0001] The invention relates to a device for storing and quickly replacing nozzles in wind tunnel equipment, belonging to the field of experimental aerodynamics. Background technique [0002] In a transonic wind tunnel, the nozzle is an important component to ensure that the test section obtains a uniform flow field at the design Mach number, and its performance has an important impact on the aerodynamic test results. At present, there are mainly two types of storage and replacement devices for solid-wall nozzles. One is that the nozzle block is separated from the nozzle box, and the nozzle box is placed on a carriage, which moves along a track perpendicular to the axis of the wind tunnel. Different nozzle blocks are replaced to achieve different Mach numbers. This method is mainly used in wind tunnels with small cross-sections in the test section. Another method is that the nozzle block and the nozzle box are fixed and placed on the carriage. Each Mach numb...
