摘要: An aircraft engine cowling (102) comprises a first cowling portion (104) and a second cowling portion (106) moveable relative to each other. A cowling latch (114) secures the first cowling portion (104) and the second cowling portion (106) in a closed position. The aircraft engine cowling (102) further comprises a deflection limiter band (122) and a deflection limiter latch (124) moveable between an engaged state and a disengaged state for the deflection limiter band (122). An interlock mechanism (240) prevents disengagement of the cowling latch (114) while the deflection limiter latch (124) is in the engaged state. The interlock mechanism (240) includes a lock element (124, 126) moveable between a first position that prevents disengagement of the cowling latch (114) and a second position (222) that enables disengagement of the cowling latch (114). The interlock mechanism (240) also includes an indicator paddle (242) movable to contact the deflection limiter latch (124). A linkage assembly (510) coordinates movement of the lock element (124, 126) with movement of the indicator paddle (242).

摘要: L'invention concerne une structure intérieure fixe (200) pour une nacelle et comportant des panneaux d'extrémité (200a), un panneau intermédiaire (200c) en demi-cylindre et entre les panneaux d'extrémité (200a), des éclisses (210a) entre le panneau intermédiaire (200c) et chaque panneau d'extrémité (200a), où chaque éclisse (210a) est constituée d'une peau (312) avec face intérieure (312a) fixée aux panneaux (200a, 200c) et au moins un enfoncement (314) en saillie par rapport à une face extérieure (312b), et un patin (506) fixé à chaque surface de fixation (316) d'un enfoncement (314), où chaque patin (506) de l'éclisse supérieure (210a) est en appui contre une surface d'un mât réacteur (108) et où chaque patin (506) de l'éclisse inférieure est en appui contre un patin (506) d'une éclisse inférieure d'une autre structure intérieure fixe (200).
Avec un tel arrangement, il n'est plus nécessaire de mettre en place une structure en nid d'abeilles flexible.-

摘要: An assembly is for an aircraft propulsion system (20). This assembly includes a fixed structure (60), a translating structure (62) and a thrust reverser (36). The translating structure (62) is configured to translate between a stowed position and a deployed position. The thrust reverser (36) includes a blocker door (58), a linkage mount (176) and an actuation linkage (86). The blocker door (58) is pivotally coupled to the translating structure (62). The linkage mount (176) includes a mount link (178), a mount spring (180) and a mount stop (182). The mount link (178) is pivotally coupled to the fixed structure (60) about a pivot axis (230). The mount spring (180) is configured to bias the mount link (178) about the pivot axis (230) against the mount stop (182). The actuation linkage (86) operatively couples the blocker door (58) to the mount link (178).

摘要: Powder-based additive manufacturing processes for producing integral parts with multiple metallic materials are disclosed. The integral parts are printed as single pieces by joining different metallic materials together during printing. A combination of different powder-based additive manufacturing processes or the same process can be used to produce the integral part.
