Abstract
The present invention concerns an emergency opening control device for an aircraft door comprising: at least one triggering mechanism (10) for emergency opening, at least one door actuator (8), and means of power supply (14, 16) to the actuator driven by the triggering mechanism. The device also comprises means (20) for modification of the output delivered by the means of power supply to the actuator, to allow the door to be opened more slowly in an initial phase of opening and more rapidly in at least one subsequent opening phase.
Claims4
A method for automatic emergency opening of an aircraft door (2), in which the door receives a first actuation from an actuator (8) in an initial phase of opening the door and a second actuation from said actuator in a subsequent phase of opening the door, said actuator being supplied with power, said power being modified by means for modification of the power delivered to the actuator, such that the power delivered to the actuator in said initial phase is greater than the power delivered to the actuator in said subsequent phase, wherein said means for modification of the power delivered to the actuator comprise a distributor to successively link said actuator to a first then to a second source of pressurized gas.
A method for automatic emergency opening of an aircraft door (2), in which the door receives a first actuation form an actuator (8) in an initial phase of opening the door and a second actuation from said actuator in a subsequent phase of opening the door, said actuator being supplied with power, said power being modified by means for modification of the power delivered to the actuator, such that the power delivered to the actuator in said initial phase is greater than the power delivered to the actuator, in said subsequent phase, wherein said means for modification of the power delivered to the actuator comprise a regulating valve between said actuator and a source of pressurized gas, said regulating valve comprising a passage outlet for the pressurized gas and a plug capable of partially blocking or entirely liberating the passage outlet.
