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.

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blocking element prevents the locking element from moving to the second position unless the blocking element is first withdrawn.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such a way that if the thrust reverser moves toward a deployed position without the blocking element having first been withdrawn, the force produced by the contact between the thrust reverser and the locking element produces a torque that tends to move the lock into its closed position.
