阅读说明：本技术 改进的气体涡轮引擎 (Improved gas turbine engine ) 是由 M.J.惠特尔 P.邓宁 R.M.汤斯 于 2019-07-31 设计创作，主要内容包括：本公开提供了一种高效的气体涡轮引擎。该气体涡轮引擎的风扇经由齿轮箱从涡轮驱动,使得该风扇具有比该驱动涡轮低的旋转速度,从而提供效率增益。该高效的风扇系统与具有低冷却流需求和/或高温性能并且对于给定功率可具有特别低质量的核心相配合。(The present disclosure provides an efficient gas turbine engine. The fan of the gas turbine engine is driven from the turbine via a gearbox such that the fan has a lower rotational speed than the driven turbine, thereby providing an efficiency gain. The efficient fan system is compatible with cores that have low cooling flow requirements and/or high temperature performance and can have particularly low quality for a given power.)
