Abstract: Numerical simulation of combustor performance of QD128 卿 turbine was finished using CFD method・ The results indicated: Flow distribution of combustor is reasonable, velocity field of combustor meets the design requirements. Outlet average temperature is 1 298K,hot spot temperature is 1 486 Kt the temperature distribution curve meets the design requirementstand OTDF =0. 280,RTDF =,which are slightly higher than the level of prototype aircrafts. The results enrich the design data of QD128 gas turbine,and provide reliable reference for the running and improving・
