Description

technical field [0001] The invention relates to the field of aviation testing, in particular to an aviation fan testing vehicle. Background technique [0002] At present, there is no dedicated cooling fan test bench for civil aircraft equipment. Usually, aircraft maintenance companies disassemble the cooling fan and test the fan directly. Usually, in order to meet the needs of the test, it is necessary to set up a distribution line for each test, and the work is repetitive and cumbersome. In addition, the fan is usually only fixed on a platform without any protection, which is easy to cause accidents. For example, in order to complete the output function test of the equipment cooling exhaust fan of CRJ700 aircraft, it is first necessary to remove the exhaust fan and fix it on the workshop bench, and then provide 115V 400 Hz AC power to the equipment cooling fan, so that the fan can work normally Detect the working current of the fan in the state. During this test, it is n...
