Progress in dynamic design and performance evaluation of high bypass ratio turbofan engine mounting
This paper reviews the dynamic design and evaluation of mounting of turbofan engines with large bypass ratio.First,starting from the requirements of vibration damping design,the great significance of dy-namic design of engine installation section is discussed,and the main structural forms and characteristics of mounting are elaborated.Furthermore,based on military and civilian standards and engineering practice experience,the technical requirements of dynamic design of engine mounting are summarized.Then,the research status of turbofan engine mounting at home and abroad is reviewed from the aspects of dynamic design,performance evaluation and system verification.The paper points out that the gap between China and foreign countries mainly lies in design requirements,design concepts and application practice experi-ence.On this basis,the development trend and hot spots of engine mounting dynamics design and perform-ance evaluation technology of large bypass ratio turbofan engine are prospected.
