摘要： Disclosed herein is a hybrid mechanical/reactive pressure prevention system that includes a passive pressure control device (202) operably coupled to a door that allows air within a pressurized vehicle to flow out of the pressurized vehicle. An event module detects a door event in the pressurized vehicle. The door event indicates that a door is not secure and air within the pressurized vehicle is being released through the passive pressure control device. An altitude module (208) determines an altitude of the pressurized vehicle in response to detecting the door event. An electronic pressure control device (204) one or more of reduces air inflow into the pressurized vehicle and increases air outflow out of an active pressure control device of the pressurized vehicle in response to the altitude of the pressurized vehicle being below a cutoff altitude.

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： An access system for a vehicle includes a door (110) moveably coupled to a portion of a fuselage (106). The door (110) is configured to be moved between an open position in which an opening (108) of an internal chamber is opened, and a closed position in which the opening (108) of the internal chamber is closed. One or more actuators (112) are secured to the door (110). The one or more actuators (112) are configured to move the door (110) between the open position and the closed position.
