Title
(EN) AIRCRAFT FUEL TANK INERTING SYSTEM WITH MECHANICALLY-OPERABLE OVER-TEMPERATURE SHUTOFF VALVE
(FR) SYSTÈME D'INERTAGE DE RÉSERVOIR DE CARBURANT D'AÉRONEF COMPRENANT UNE SOUPAPE D'ARRÊT EN CAS DE SURCHAUFFE ACTIONNABLE MÉCANIQUEMENT
Abstract
(EN)
A fuel tank inerting system (100) includes a mechanically-operable over-temperature shutoff valve (10). The valve includes a shape memory actuator (18) that is configured to sense an over- temperature condition of fluid flowing through the valve and thereby actuate a locking mechanism (16) to deploy a valve member (14) to close the valve in the event of the over-temperature event. The locking mechanism (16), when in a locked state, is configured to hold the valve member (14) in an open position during a normal operating condition of the valve. The shape memory actuator (18) includes a shape memory material that is configured to change shape when heated to a predefined temperature. When the temperature of fluid flowing through the valve increases the temperature of the shape memory material to the predefined temperature, or above, the shape memory actuator (18) moves the locking mechanism (16) to a release state, thereby releasing the valve member (14) which is biased to close the valve.

La présente invention concerne un système (100) d'inertage de réservoir de carburant qui comprend une soupape d'arrêt en cas de surchauffe actionnable mécaniquement (10). La soupape comprend un actionneur à mémoire de forme (18) qui est conçu pour détecter une condition de surchauffe de fluide s'écoulant à travers la soupape et actionner ainsi un mécanisme de verrouillage (16) pour déployer un élément (14) de soupape pour fermer la soupape en cas d'événement de surchauffe. Le mécanisme de verrouillage (16), lorsqu'il se trouve dans un état verrouillé, est conçu pour maintenir l'élément (14) de soupape dans une position ouverte pendant une condition de fonctionnement normal de la soupape. L'actionneur à mémoire de forme (18) comprend un matériau à mémoire de forme qui est conçu pour changer de forme lorsqu'il est chauffé à une température prédéfinie. Lorsque la température du fluide s'écoulant à travers la soupape augmente la température du matériau à mémoire de forme jusqu'à une température supérieure ou égale à la température prédéfinie, l'actionneur à mémoire de forme (18) déplace le mécanisme de verrouillage (16) jusqu'à un état de libération, libérant ainsi l'élément (14) de soupape qui est sollicité pour fermer la soupape.
