A Review of Research Progress on Discreteness Control of Compressor Blade Machining Error
The aero-engine compressor blisk is usually designed as a rotationally symmetric structure.However,in actual machining,the discreteness of machining errors between different blades on the same stage blisk and the individual blade itself will adversely affect the flow field parameters.Therefore,improving the consistency of machining errors of blisk's blades has become a common concern.This paper reviews the related researches on the influence of machining error dispersion on aerodynamic performance of different blades of the same stage in recent years,and the related results of error dispersion control under strong time-varying characteristics of machining process.The error dispersion phenomenon and its causes,the influence law on performance and the control method of machining error dispersion are discussed in three aspects.Finally,the development trend of error dispersion machining control method in the future is prospected,which provides a reference for future related research work.
