Actuator for gas-operated emergency opening of an openable element of an aircraft, having means for venting the gas

Actuator for emergency opening of an openable element (Co) of an aircraft, having:

• a thrustor (1) arranged to be connected, at one (3) of its ends, to said openable element and, at its other end (4), to a reference element (Re) of the aircraft to which said openable element is linked,
• a pressurised-gas reservoir (2), said gas reservoir (2) having a membrane (6) 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 (7) 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 (8),
• characterised in that said actuator additionally comprises:
• means (9) for venting, away from the thrustor, the gas contained in the reservoir, via a second fluid circuit (10) 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.
