Based on the similarity theory of turbine engines and considering the layout feature of the engines on the sample helicopter, comparisons had been made on the NG-P characteristics of the engines before and after assembled to the helicopter, and analysis had been performed on the influential factors. A proposal had been propounded on the helicopter lfight test of engine power loss, which is overall considering the major inlfuential factors including assemble schemes, lfight regimes, lfight environment and so on.
