Simulation bias can cause the performance difference during turboshaft engine tests in altitude test facility(AFT).Based on numerical simulation and tests research of a turboshaft engine
a performance correction method of combining the resemble conversion with small deviation analysis was put forward.The results show that the differences of output power and specific fuel consumption were drop from about 3.0% obtained by the resemble conversion to about 1.0%
so this combination method is reasonable and scientific for correcting the influence of simulation bias on the engine performance.
