摘要
阐述了涡轮基组合循环发动机(TBCC)进气道模态转换国内外的研究现状,并结合串联、内/外并联等典型TBCC发动机的主要特点对其模态转换气动技术研究存在的主要问题及未来主要发展趋势进行对比分析。给出了TBCC模态转换过程需要进一步解决的主要关键气动问题,主要包括新型高性能TBCC进气道模态转换设计技术、模态转换过程高精准度数值模拟及风洞试验技术、模态转换条件对进气道出口流场性能和起动特性影响、模态转换过程分流板区域内外流复杂非定常流动机理及对飞行器气动特性的影响等,为TBCC组合动力模态转换气动技术研究提供参考。
The study status, main problems and development tendency of Turbine-Based Combined Cycle （TBCC） inlet mode transition aerodynamic technology were discussed and compared under different combining ways such as co-axial type and over/under type. For analyzing the key aerodynamic issues which should be further solved during mode transition, the research work including new high performance design methods, highly accurate numerical simulation and wind tunnel experimental technologies, influence of inlet performance and starting characteristics caused by mode transition condition, complicated unsteady in/external flow mechanism around the flow splitter during mode transition and the impacts on the aerodynamic characteristic and flight stability of the high Mach number vehicle, were proposed and which can provide reference for TBCC engine and the relative vehicle investigation.
