ABSTRACT:
A latch system 34 for the nacelle cowling 24 of a gas turbine engine 10 is disclosed. The latch system includes a coupling 36 which may be remotely operated by means of a cable 44. In one embodiment, a support structure 14, the coupling, the cable and a linkage system 48 for applying tension to the cable extends circumferentially about the interior of the cowling to provide constricting force on the cowling to increase the structural rigidity of the cowling. In another embodiment, the coupling has jaws 58 and 60 which are movable from a locked to an unlocked position as a result of the relative movement between the jaws and a housing 50. A linkage system is provided for tensioning the cable which in the locked position uses the tension in the cable to resist operative forces which might seek to open the latching system.
