  • Engine rating control strategy based on the life consumption of high pressure turbine (HPT) blade was put forward.The thrust requirement temperatures of HPT blade in various environments were obtained by flight mission simulation using aircraft and engine models.Reverse engineering method was used to calculate the life consumption of HPT blade.Results show that the control strategy of reducing HPT blade' temperature can significantly cut down the life consumption of HPT blade in various conditions while meeting the thrust requirement.It verifies that the life consumption calculation method of HPT blade is simple and feasible.By continuously adjusting the engine HPT environment temperature approaching the thrust requirements baseline,the service life of the engine could be effectively extended.Results state that the engine rating control based on the life consumption of HPT blade is effective to reduce the engine life cycle cost,playing a significant role for civil aviation engine control and operation.
