航空发动机防喘系统扩稳构件优化研究

为获得防喘系统的最佳效能，采用温度畸变发生器作为逼喘装置，分别给出了不同发动机扩稳构件的试验结果。优化试验以发动机进口临界温升为目标。讨论了某涡扇、涡喷发动机扩稳构件在不同形式组合方案下的扩稳效果。结果表明．防喘系统扩稳效果最为显著的是采用减少或切断燃油的手段，但其缺点是会导致推力下降较大，因此扩稳方案需综合考虑，应从有效性、发动机重量、机动飞行和可靠性能力等方面进行权衡。

Experimental Study on Stability Enhancement Components Optimization of Aero-engine Anti-surge System

For obtaining the optimal efficiency of the anti-surge system,this paper adopts the temperature distortion generator as the force-surge system and presents the test results of different engines'stability enhancement components.The optimization experiment's goal is the inlet critical temperature of the engine.The effect of stability enhancement components at different combined schemes of turbofan and turbojet engine is discussed.The results show that the most effective anti-surge system is the one using thro...
