For the requirement of a turbine-shaft engine research
surge experimentation had been done exploringly in a whole engine test-bed.This paper describes engine surge
the design of surge experimentation method
experimentation equipment and the process of the experimentation.In the end
the results of the experimentation have been analysed and summarized
the results make clear that the experimentation method is valid
connecting high pressure air to the engine bleeds can do the engine surge experimentation successfully.Consequently the real surge margin of the compressor installed in the overall engine can be gotten.
