    Abstract: There is disclosed an aircraft engine assembly including an engine having an engine shaft; an output shaft; a clutch in driving engagement between the engine shaft and the output shaft. The clutch has a first component in driving engagement with the engine shaft and a second component. The clutch is operable between first and second configurations. In the first configuration, the first component is rotatable relative to the second component and the engine shaft is rotatable relative to the output shaft. In the second configuration, the first and second components are engaged with one another and the engine shaft rotates with the output shaft. A mechanical lock is operable between first and second positions. In the first position, the mechanical lock is disengaged from the first component. In the second position, the first and second components are secured for joint rotation one relative to the other.

    Abstract: A compound engine assembly including a compressor, an engine core including at least one rotary internal combustion engine and having an inlet in fluid communication with an outlet of the compressor, a turbine section having an inlet in fluid communication with an outlet of the engine core and configured to compound power with the engine core, and an air conduit having at least one heat exchanger extending thereacross. An outer wall of the air conduit has a plurality of openings defined therethrough downstream of the heat exchanger(s), each selectively closable by a pivotable flap movable between a retracted position where the opening is obstructed and an extended position away from the opening. Each opening defines a fluid communication between the air conduit and the ambient air when the respective flap is in the extended position. A method of directing flow through a compound engine assembly is also discussed.

    Abstract translation: 一种复合发动机组件，包括压缩机，包括至少一个旋转内燃机的发动机内燃机，并且具有与压缩机的出口流体连通的入口，具有与发动机芯的出口流体连通的入口的涡轮部分，以及 配置成与发动机芯组合动力，以及具有至少一个在其上延伸的热交换器的空气管道。 空气管道的外壁具有在热交换器的下游限定的多个开口，每个开口可由可枢转的翼片选择性地关闭，所述枢转折翼可在开口被阻塞的缩回位置和远离开口的延伸位置之间移动。 当各个翼片处于伸出位置时，每个开口限定了空气管道和环境空气之间的流体连通。 还讨论了引导流过复合发动机组件的方法。
