摘要
为评估和优化发动机防喘系统的效能,采用温度畸变发生器作为逼喘装置,分别给出了某涡扇、涡喷发动机扩稳构件在不同组合方案下的试验结果.比较和讨论了防喘系统不同扩稳构件的扩稳效果.试验结果表明:发动机防喘系统扩稳效果最为显著的是采用短时切断燃油以及导叶、放气等调节手段,但其缺点会带来较大的推力损失和系统的复杂性;而采用切油加导叶调节的手段尽管扩稳效果不如前者明显,但其推力损失较小且系统易于实现.
To assess and optimize the optimal efficiency of the anti-surge system,this paper adopted the temperature distortion generator as the force-surge system and presented the test results of certain turbojet and turbofan engine's stability enhancement components at different combinatorial projects respectively,compared and discussed the effects of various stability enhancement components of the anti-surge system.The test results show that the most effective anti-surge system is the one using throttle cutting fo...
