Simplified Removable Ground Test-Bed for Testing Turbofan Engine

A new simplified removable ground test-bed was designed for testing a certain turbofan engine. The facilities are 5. 5 m long, 1. 5 m wide, 2. 2 m high and not more than 4. 5 t of its empty weight. There are four rubber wheels that could be towed. There is an independent electrical measurement and control system to test the rotational speed of rotors, the gas pressure of the compressor, the exhaust gas temperature, etc. Cooperated with the oil truck and the electric power supply truck, the turbofan engine could be preserved on the ground and started to the idling regime. While running, the parameter of the engine could be recorded, disposed and displayed. In addition, the facilities were successfully applied to the plateau experiment in order to research how the atmosphere pressure affects the start of engines. Some data are given in the paper.
