摘要：本文参考俄罗斯新研制的一种双通道燃气轮机ΓΤУ-18ПС,它的外涵增压空气经与内涵燃机的排气换热后驱动热空气涡轮,该涡轮与内涵燃机动力涡轮共轴输出功率,可大幅提高燃气轮机的输出功率和循环效率。将这种空气底部回热复合循环方式用于某型涡扇发动机改型燃气轮机方案,经计算分析可使燃气轮机的性能和热效率明显提高。

Abstract: This paper gives a
discussion on the newly dual-ducted ΓΤУ-18ПС gas turbine developed in Russia.In
this turbine,the compressed air passing the engine exchanges heat with air flow
passing through the core to drive the hot air turbine.Air turbine shares the
same shaft with the power turbine to output power.In such way,the gas turbine
might output much higher power and achieve cycle efficiency greatly.This method
of air basal heat regenerative cycle is used in the plan for gas turbine
modified on the turbine engine.The calculation analysis shows that this method
may improve the turbine performance and its heat efficiency.
