The present invention concerns an emergency opening control device for an aircraft door 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.
대표청구항
▼
1. 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, andmeans ( 18 , 80 , 81 , 82 )
1. 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, andmeans ( 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. 2. 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, andmeans ( 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 are pneumatic means comprising a single source ( 15 ) of pressurized gas, in that the means for modification of the power delivered to the actuator comprises a regulating valve ( 82 ) for regulating a gas flow between the source of pressurized gas and the actuator,wherein said regulating valve ( 82 ) comprises a passage outlet (O) for the pressurized gas and a plug ( 81 ) capable of partially blocking or entirely liberating the passage outlet. 3. 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, andmeans ( 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 for modification of the power delivered to the actuator comprise a time delay sequencer ( 18 ) for delivering a first power to the actuator during the initial phase and a second power greater than the first power in the subsequent phase,wherein the time delay sequencer comprises a trigger spring ( 66 ) capable of being released by the triggering mechanism ( 10 ) and linked to the means for modification of the power delivered to the actuator, the trigger spring being coupled to a shock absorber ( 60 , 62 , 64 , 65 ). 4. Aircraft emergency evacuation device comprising:an aircraft exit door ( 2 ),at least one item of passenger evacuation equipment ( 4 ) capable of being deployed close to the door, anda control device for emergency opening of the door,such that the emergency opening control device conforms to any of the preceding claims. 5. The evacuation device according to claim 4, further comprising means of deployment of the passenger evacuation equipment, said means of deployment being activated when said emergency opening triggering mechanism ( 10 ) is activated. 6. The evacuation device according to claim 5, wherein the evacuation equipment is stowed in the doors, said door being delimited by a frame, and said evacuation equipment is capable of being connected to said frame.
