| To improve predicting accuracy of overall performance for off-design points，a 0D/2D coupling method is developed.Forcus
on a three-spool turboprop，a 0D overall performance simulation model for the performance of turboprop based on T-MATS is established.
Two optimum plans to the distribution for useful output are presented. A 2D flow-path and balde design method are developed to free
turbine and jet pipe in the original plan and two optimized plans. Through S1 flow surface and through flow CFD calculation, aerodynamic
performance of designed component meets the target of overall performance of engine. In order to improve predicting accuracy of engine
overall performance inuoff-design points，a 0D/2D coupling overall performance prediction method was adopted to analyze three plans. The
results show that Plan 1 reduces equivalent specific fuel consumption for 2.11% at design point，1.2% at cruise point and 2% at ground state. |
