CA 2710202
An uplock assembly for retaining and releasing landing gear systems, said uplock assembly comprising: a thermal actuator comprising: a chamber configured to contain expansible material therein; a heating mechanism coupled to said chamber for heating said expansible material and causing volumetric expansion thereof; a piston slidably coupled to said chamber and adapted to extend in response to said volumetric expansion; and an uplock release mechanism releasably engaged by said piston when extended such that said engaged uplock release mechanism causes the release of said landing gear.
L'invention concerne un verrou de position rentrée pour des systèmes de retenue et de libération de train d'atterrissage, ledit verrou de position rentrée comportant : un actionneur thermique comportant : une chambre configurée pour contenir un matériau expansible; un mécanisme de chauffage relié à ladite chambre pour chauffer ledit matériau expansible et provoquer sa dilatation volumique; un piston coulissant dans ladite chambre et conçu pour sortir sous l'action de ladite dilatation volumique; et un mécanisme de libération de verrou de position rentrée dans lequel s'engage de façon amovible ledit piston lorsqu'il est sorti, de telle sorte que ledit mécanisme de libération de verrou de position rentrée provoque la libération dudit train d'atterrissage.
