    • A variable cycle propulsion unit comprises at least two turbojet engines of the bypass type in which the low pressure compressor of each engine is in two parts connected by a shaft, and the flow of compressed air issuing from the first part of the low pressure compressor of a first of the engines is supplied to the second part of the low pressure compressor of a second of the engines and the flow of compressed air issuing from the first part of the low pressure compressor of the second engine is supplied to the second part of the low pressure compressor of the first engine. At full throttle operation the combustion chambers of the two engines are both ignited, and at operation at reduced engine speeds the combustion chamber of one of the engines is extinguished and the engine windmills while the other engine continues to run normally.
    • 可变循环推进单元包括至少两个旁通型涡轮喷气发动机,其中每个发动机的低压压缩机在两个部分中通过轴连接,并且从低压压缩机的第一部分排出的压缩空气流 第一发动机被供应到第二发动机的低压压缩机的第二部分,并且从第二发动机的低压压缩机的第一部分排出的压缩空气流被供给到第二发动机的第二部分 第一台发动机的低压压缩机。 在全油门操作时,两个发动机的燃烧室都被点燃,并且在发动机速度降低的情况下,一个发动机的燃烧室熄灭,并且发动机风车,而另一个发动机继续正常运行。
