摘要/Abstract

摘要： 当增加动叶转角以进一步提升超、跨声速轴流压气机级负荷时,为解决其内部流动问题,提出了吸附式低反动度超、跨声速轴流压气机气动设计原理。分析了在该气动设计原理指导下,级内参数的演变规律与相互影响。利用该气动设计原理完成了一高负荷超声速轴流压气机气动设计,三维粘性数值模拟结果表明,在叶尖切线速度370m/s的前提下,实现了一级压比2.5,效率87%的压气机级设计。 

Abstract: A new aerodynamic design principle has been put forward to solve the inner flow problems of the supersonic or transonic compressors with large deflection which can further increase the stage load. This principle is called as low-reaction and aspirated aerodynamic design principle for supersonic or transonic compressor. A verification of the principle has been carried out. The three-dimensional viscous numerical simulation results show that a stage pressure ratio 2.5with efficiency 87% at tip tangential speed 370m/s has been attained, which demonstrates the possibility of this principle to increase the stage load. 
