在燃气轮机装置中采用可转导叶作为压气机的防喘措施,是目前广泛采用的方法。与单纯的放气防喘措施相比,它具有能扩大发动机许用功率范围,提高低工况经济性,改善发动机的启动加速性能及改善机舱工作条件等优点。特别是对于全工况舰用燃气轮机而言,要求发动机具有广泛的稳定工作范围及良好的部分负荷性能,采用可转导叶则更为适宜。
The use of a switchable vane as an anti-asthma measure for gas turbines in gas turbine installations is currently a widely used method. Compared with the purely deflated anti-asthma measures, it has the advantages of expanding the allowable power range of the engine, improving the economy of low working conditions, improving the starting acceleration performance of the engine, and improving the working conditions of the cabin. Especially for full-service marine gas turbines, the engine is required to have a wide range of stable operating conditions and good partial load performance, and the use of a switchable vane is more appropriate.
