The results show that the compressor performance at low speed is effectively improved and the surge limit is expanded with optimization of the stator vane. 研究结果表明:通过静叶优化,有效地改善了压气机的低转速性能,拓宽了稳定工作边界;
Many limits in the process of engine acceleration have been studied such as compressor surge margin, overtemperature limit, overspeed limit, rich extinction in combustor, the maximum fuel flow and limit of the actuator property. 在研究中,考虑了发动机加速过程中的压气机喘振边界、涡轮最高温度限制、转子最高转速限制、燃烧富油熄火限制等各种约束条件,以及执行机构的惯性、延迟等机械特性。
The largest Lyapunov exponents of the pressure signal of a certain engine with eight axial compressor stages are investigated: The stall and surge inception points possessing the same dynamic characteristics are all located on the boundary of a limit circle. 研究某型发动机的八级轴流压气机级间压力信号的最大Lyapunov指数,推断出失速和喘振的起始点具有相同的动力学特性:都为某一极限环边界上的点。
