Abstract

The invention discloses an environmental test cabin comprising a hollow cylindrical test cabin body; the test cabin body is arranged on a mounting foundation in the horizontal direction, and the wall surface of the test cabin body is provided with an inlet and outlet for a to-be-tested machine for test and test equipment to enter and exit from the test cabin body. A sliding cabin door for sealing the inlet and outlet is arranged at the inlet and outlet, is connected to the test cabin body and is horizontally arranged in a sliding manner along the axial direction of the test cabin body so as to open or close the test cabin body. According to the sliding type cabin door, the design size of the sliding type cabin door can be effectively reduced, and then the construction cost of an environment test cabin is greatly reduced; the environmental test cabin is simple in overall structure and low in manufacturing cost, the driving force only needs to overcome the friction force generated when the sliding cabin door slides, and the driving force is small, so that the driving mechanism which is simple in structure, low in manufacturing cost and simple in driving operation can be selected to drive the sliding cabin door, and the defects of complex structure, large size, high cost, oil leakage and the like caused by hydraulic drive are overcome.

Description

technical field [0001] The invention relates to the technical field of aero-engine test devices, in particular to an environmental test chamber. Background technique [0002] Before the design of the aero-engine is finalized, it is necessary to complete high and low temperature start tests, and plateau start tests, etc. During the test, it is necessary to simulate the temperature and pressure of the engine inlet and the exhaust pressure. The 5km plateau starting test needs to simulate the atmospheric environment of 54.0kPa(A) / -17.5℃. In order to complete the above test, the engine under test is generally placed in the environmental test chamber, the inlet and outlet of the environmental test chamber are connected to the external air source, the air of a certain temperature and pressure enters from the inlet of the environmental test chamber, the engine inhales and burns, and the high-temperature gas discharged It is discharged through the outlet of the environmental test ch...
