Air turbine starter property testing device

Abstract

The invention discloses an air turbine starter property testing device. The device includes a transmission mechanism which includes a pedestal, a transmission shaft, a drive cylinder, a connecting guide rod, a connecting assembly and an output flange. The transmission shaft is arranged on the pedestal in a first direction. One end of the transmission shaft is in transmission connection to an output shaft of a torquemeter, and the other end of the transmission shaft is coaxially connected to the output flange. A cylinder body of the drive cylinder is fixed to the pedestal. A telescopic end of the drive cylinder is movably connected to one end of the connecting guide rod. The middle part of the connecting guide rod is provided with waist-shaped holes in the length direction of the connecting guide rod. The connecting assembly is slidingly arranged at the waist-shaped holes of the connecting guide rod. The connecting assembly is intended for detachably connecting the transmission shaft and the output flange. The other end of the connecting guide rod extends in a second direction. The other end of the connecting guide rod is movably connected to the pedestal. The first direction and the second direction are in non-parallel arrangement. The output flange and a brake mechanism are in transmission connection. According to the invention, the device is easy to operate, is safe and reliable, and has high automation.

Description

technical field [0001] The invention relates to the technical field of aircraft starting, in particular to an air turbine starter performance testing device. Background technique [0002] The air turbine starter is the core component of the aircraft starting system, and its main function is to start the engine to ignite and work normally. The air turbine starter uses compressed air to bring the engine to a certain speed and then disconnects it. After the engine is ignited normally, the starter stops working, or after the engine suddenly stops in the air, the starter starts the engine for a second time. [0003] The air turbine starter performance test equipment is to load different inertial loads on the air turbine starter under the rated intake pressure, flow and temperature conditions, and the air turbine starter accelerates to a certain speed to test the performance of the air turbine starter equipment. [0004] In the prior art, the air turbine starter performance test...

Problems solved by technology

[0004] In the prior art, the air turbine starter performance test equipment generally uses the inertia wheel to load. If different loads are required, the inertia wheel needs to be replaced manually. The operation is more complicated, and there is a safety hazard when the inertia wheel runs at high speed. Accident, unimaginable consequences
