Abstract:
1. An actuator for emergency opening of an openable element of an aircraft, the actuator comprising: a thrustor arranged to be connected, at one of its ends, to said openable element and, at its other end, to a reference element of the aircraft to which said openable element is linked, a pressurised-gas reservoir, said gas reservoir having a membrane capable of being perforated in order to actuate said thrustor for the purpose of emergency opening of the openable element by release of the gas from the reservoir, a movable perforator arranged to perforate said membrane of said reservoir in order to release the gas contained in the latter into the thrustor via a first fluid circuit, a venting circuit capable of venting, away from the thrustor, the gas contained in the reservoir, via a second fluid circuit which does not actuate said thrustor, in the event of accidental rupture of said membrane occurring in the absence of displacement of said movable perforator, wherein a movable valve which is actuated by the gas released from the reservoir and the movable valve capable of moving relative to the movable perforator between the following two positions: a first position, referred to as the position of rest, in which said venting circuit for venting the gas contained in the reservoir away from the thrustor, in the event of accidental rupture of said membrane, is active, said second fluid circuit being open, and a second position, referred to as the active position, in which said venting circuit for venting the gas contained in the reservoir away from the thrustor, in the event of accidental rupture of said membrane, is inactive, said second fluid being closed and said first fluid circuit being open.
