A comprehensive test bench for aircraft aerodynamic accessories

Abstract

The invention discloses an aircraft aerodynamic accessory comprehensive test bench, which belongs to the field of aircraft aerodynamic accessory test equipment. The comprehensive test bench includes an air supply system, a medium-pressure air path and a low-pressure air path. The gauge and pressure regulating valve are connected to the test area, and the low-pressure gas circuit is also equipped with an electric heating group that can be heated to different temperatures. The test area is connected to a computer that collects the temperature or pressure signals of the medium-pressure gas circuit and the low-pressure gas circuit. The aircraft aerodynamic accessory comprehensive test bench of the present invention has a reasonable layout, fully considers the direction of the pipeline and the difference between different test accessories, distinguishes low-pressure and medium-pressure air paths, realizes full utilization of air sources, and can maintain various aircraft aerodynamic accessories , saving costs and improving work efficiency.

Description

technical field [0001] The invention relates to a simulation test device for aircraft aerodynamic accessories, in particular to a comprehensive test bench for aircraft aerodynamic accessories. Background technique [0002] Pneumatic accessory maintenance occupies an important position in aircraft accessory maintenance. Aircraft aerodynamic accessories mainly include: pressure shut-off valve, pressure regulation valve, flow control valve, pressure shut-off valve, air cycle machine, air turbine starter, anti-icing Therefore, the maintenance of pneumatic accessories mainly includes tests on air cycle machines, air radiators, and valves. The existing aircraft maintenance test bench is relatively simple, and can only be repaired for a specific accessory. If a test bench can be developed that can repair multiple accessories, the maintenance cost can be greatly reduced, but at the same time, different pneumatic accessories can be maintained. It is necessary to consider the differe...

Problems solved by technology

The existing aircraft maintenance test bench is relatively simple, and can only be repaired for a specific accessory. If a test bench can be developed that can repair multiple accessories, the maintenance cost can be greatly reduced, but at the same time, different pneumatic accessories can be maintained. It is necessary to consider the difference in gas source pressure and heating temperature, and at the same time ensure a stable gas supply capacity
