In view of the abnormal decline of revolution,the high total temperature of the gas turbine exit and the long starting time during the starting process of a core engine,several factors affecting the starting-up performance of the core engine are analyzed.Combining the performance calculating model with the experimental data,the optimization scheme of starting-up fuel-supplying law was proposed in this paper,and experiment results showed that,by optimizing the starting-up fuel-supplying law,it is able to avoid the abnormal decline of revolution during the starting process,decrease the total temperature of the gas turbine exit and the starting time,which can improve the starting performance of the core engine.
