摘要： An aircraft propulsive power unit (19) comprises a nacelle structure (20) housing an engine and having a forward nacelle portion (21) and a rearward nacelle portion (131). The rearward end of the forward nacelle portion (21) in an operational position adjoins the forward end of the rearward nacelle portion (131) and the forward end of the forward nacelle portion (21) includes an intake opening leading to an intake barrel (28) upstream of the engine for the supply of intake air to the engine. The forward nacelle portion (21) has an uninterrupted or substantially uninterrupted low drag exterior surface thereover and the power unit includes support structure to support the forward nacelle portion (21) while permitting it to be moved forwardly on the support structure from the operational position to a forward position in which it is supported by the support structure forwardly of the operational position to provide access to components of the power unit (19) which are inaccessible with the forward nacelle portion (21) in the operational position.

摘要： An aircraft propulsive power unit (19) comprises an engine (10), a nacelle structure (20) which houses the engine (10) and which includes displaceable nacelle portions (21A, 21B) which form a forward part of the nacelle structure (20) and which take up operational positions in which a forward end of each nacelle portion (21A, 21B) forms part of an intake opening which leads to an intake barrel (28) which is located upstream of the engine (10) for the supply of intake air to the engine (10) and which is secured to a forward component of the engine (10). Each displaceable nacelle portion (21A, 21B) includes a lipskin structure (22) which has rearwardly extending outer and inner lipskin edge portions (23, 24), and further includes an outer main skin (25). The inner lipskin edge portion (24) in the operational position of each displaceable nacelle portion (21A, 21B) adjoins the forward end of the intake barrel (28) and the the power unit (19) includes support structure (182) to support each displaceable portion (21A, 21B) while permitting it to pivot outwardly to a displaced position (28) to reveal the inner surface of the outer main skin (25) and to give access to the inner surface and to components mounted thereon.
摘要翻译：飞机推进动力单元（19）包括发动机（10），容纳发动机（10）的机舱结构（20），其包括形成机舱结构（20）的前部的可移动的机舱部分（21A，21B）），并且其承担操作位置，其中每个机舱部分（21A，21B）的前端形成进入开口的一部分，该进气开口通向位于发动机（10）上游的进气筒（28），用于供应进气到发动机（10）并被固定到发动机（10）的前部件上。每个可移动的机舱部分（21A，21B）包括具有向后延伸的外唇缘部分和内唇缘部分（23,24）的唇缘结构（22），并且还包括外主皮肤（25）。在每个可移动机舱部分（21A，21B）的操作位置的内部唇缘边缘部分（24）邻接进气筒（28）的前端，并且动力单元（19）包括支撑结构（182）以支撑每个可移动部分（21A，21B），同时允许其向外枢转到位移位置（28）以露出外主表皮（25）的内表面，并且允许进入内表面和安装在其上的部件。
