High-altitude cabin and exhaust diffuser connecting and positioning structure and high-altitude simulation test equipment

Abstract

The invention provides a high-altitude cabin and exhaust diffuser connecting and positioning structure and high-altitude simulation test equipment, and belongs to the technical field of aero-engine high-altitude simulation test equipment.The high-altitude cabin and exhaust diffuser connecting and positioning structure specifically comprises a center positioning movable part, a flexible part and a water supply part, and the water supply part is of a cylindrical structure and is located between a high-altitude cabin and an exhaust diffuser; the central positioning movable part and the flexible part are positioned on the periphery of the water supply part; the center positioning component comprises a sliding block and a sliding groove which are in relative sliding connection, the sliding block is connected with the inner wall of the high-altitude cabin, and the sliding groove is connected with an outer barrel, close to one end of the high-altitude cabin, of the water supply component. The flexible part is arranged on the outer barrel of the water supply part in a sleeving mode and located on the rear side of the center positioning component in the gas inlet direction, and the front end of the flexible part is connected with a port of the high-altitude cabin. Through the treatment scheme, the gas flow field uniformity and connection stability of the high altitude cabin and the exhaust diffuser are improved, and the use performance of equipment is effectively guaranteed.

Description

technical field [0001] The present application relates to the technical field of aero-engine high-altitude simulation test equipment, in particular to a high-altitude cabin and exhaust diffuser connection positioning structure and high-altitude simulation test equipment. Background technique [0002] The function of the high-altitude platform exhaust diffuser device is to convert part of the kinetic energy of the engine exhaust gas into pressure energy, which really simulates the engine exhaust back pressure and ambient pressure conditions. The exhaust diffuser device can fully discharge the gas energy of the engine within a certain test range under the premise of ensuring the exhaust expansion ratio of the engine, increase the simulated height of the high-altitude platform, save energy, and expand the working range of the high-altitude platform. [0003] The rear cabin of the high-altitude cabin in the high-altitude platform is connected to the exhaust diffuser. Due to the ...
