摘要： The complex mechanical gear trains and lubrication systems of conventional engine configurations are eliminated by using combinations of hydrodynamic air foil bearings, hydrodynamic solid geometry carbon seals/bearings, magnetic bearings, and electrical starter/generators that can also act as bearings to support the high speed shafts of gas turbine engines. The various bearing types and the starter/generators are arranged in such a way as to share peak loads experienced by the engine shaft during maximum aircraft maneuvers. This results in a minimal bearing and engine size.

摘要： An aircraft thrust reverser mechanism comprises a thrust reverser moveable between a deployed position in which at least a portion of gas flowing through the aircraft engine is redirected in a non-rearward direction and a stowed position in which gas flowing through the engine is not redirected. A thrust reverser lock is provided to prevent inadvertent deployment of the thrust reverser. The thrust reverser lock comprises a locking element rotatable about a pivot between a closed position in which the locking element prevents deployment of the thrust reverser and an open position in which the locking element permits the thrust reverser to be deployed. A retractable blocking element prevents the locking element from moving to the second position unless the blocking element is first withdrawn. The locking element is shaped in such a way that if the thrust reverser moves toward a deployed position without the blocking element having first been withdrawn, the force produced by the contact between the thrust reverser and the locking element produces a torque that tends to move the lock into its closed position.
摘要翻译：飞机推力反向器机构包括可在展开位置之间移动的推力反向器，在展开位置中，流过飞机发动机的至少一部分气体在非向后方向被重定向，并且其中流过发动机的气体不被重定向的收起位置。提供推力反向器锁以防止推力反向器的意外部署。推力反向器锁包括锁定元件，该锁定元件能够在关闭位置之间围绕枢轴旋转，在该位置中锁定元件防止推力反向器的展开以及锁定元件允许推力反向器被展开的打开位置。可伸缩的阻挡元件防止锁定元件移动到第二位置，除非阻挡元件首先被拉出。锁定元件的形状使得如果推力反向器朝向展开位置移动而没有阻塞元件首先被撤回，则由推力反向器和锁定元件之间的接触产生的力产生倾向于移动锁定到其关闭位置。

摘要： A sealing assembly for achieving a fluid seal between a rotatable shaft and a housing circumscribing the rotatable shaft to inhibit fluid leakage therebetween a high pressure fluid region and a relatively lower pressure fluid region. The sealing assembly includes at least one primary seal, comprising an axial stack of a plurality of diaphragm members, including an upstream diaphragm and a downstream diaphragm. A plurality of finger seal plates are positioned between the upstream diaphragm and the downstream diaphragm. The plurality of diaphragm members define a passageway in fluid communication with the high pressure fluid region and a low pressure fluid region. The sealing assembly includes at least one secondary seal positioned within the passageway and configured to convert fluid from a high pressure axial pressure balance to a low pressure axial pressure balance thereby reducing a radially inward pressure load.
摘要翻译：一种密封组件，用于在旋转轴和外壳之间实现流体密封，所述壳体围绕所述可旋转轴以抑制高压流体区域和相对较低压力的流体区域之间的流体泄漏。密封组件包括至少一个初级密封件，其包括多个隔膜部件的轴向堆叠，包括上游隔膜和下游隔膜。多个手指密封板位于上游膜片和下游膜片之间。多个隔膜部件限定与高压流体区域和低压流体区域流体连通的通道。密封组件包括定位在通道内的至少一个次级密封件，其构造成将流体从高压轴向压力平衡转换成低压轴向压力平衡，从而减小径向向内的压力负载。
