Abstract:
A control device for emergency opening of an aircraft door comprising:at least one triggering mechanism (10) for emergency opening, at least one door actuator (8), means (14, 15, 16) of power supply to the actuator (8) responding to the triggering mechanism, and means (18, 80, 81, 82) for modification of the power delivered by the means of power supply to the actuator (8), to control a slower opening of the door in an initial phase of opening and more rapid opening in at least one subsequent opening phase, wherein the means of power supply are pneumatic means comprising a first and second sources of pressurized gas, the first source of pressurized gas (14) being at a lower pressure than the second source of pressurized gas (16), and the means for modification of the power delivered to the actuator comprising a distributor (82) to successively link the actuator to the first then the second source of pressurized gas.
