The invention relates to a movable micro turbine jet engine test bed, which consists of a test bed rack and a control cabinet. An engine to be tested and various measurement sensors are installed on the test bed rack. The test bed rack is connected with the control cabinet through conducting wires. Various meters and a computer are installed in the control cabinet. The control cabinet is used for receiving test data and controlling the running state of the engine. The test bed rack consists of a flow measuring pipe, a weighing sensor, a weighing sensor support, sliding rail shafts, sliding rail shaft supports, an oil tank, moving wheels, fixed wheels, lead screw supports, a main body support steel frame, a fixing plate, a tail jet pipe support, a tail jet pipe, temperature sensors, a protection cover, a sliding plate, an engine supporting base, a pressure measuring joint, the engine to be tested, a front inner flow guide cover, sliding plate connecting blocks, a flow meter, a micro differential pressure transmitter, an electronic control unit (ECU) and pressure transmitters. The control cabinet consists of a cabinet body, various meters, the computer, four corner wheels and an ECU control assembly. The movable micro turbine jet engine test bed is flexible and convenient, and provides an equipment support for the accurate determination of the performance of the micro turbine jet engine.
