Abstract
A ram air turbine actuator having: a housing; at least one solenoid; a latch mechanism operably connected to the at least one solenoid and located within the housing, the latch mechanism in operation moves from a first position to second position when the at least one solenoid is activated; and a hydraulic pressure system operably connected to the latch mechanism, the hydraulic pressure system in operation moves the latch mechanism from the second position to the first position using hydraulic pressure from a hydraulic fluid, when the at least one solenoid is deactivated. The hydraulic pressure system is located within the housing. The hydraulic pressure is relieved when the latch mechanism is in the first position.
Claims16
A ram air turbine actuator comprising:
- a housing;
- at least one solenoid;
- a latch mechanism operably connected to the at least one solenoid and located within the housing, the latch mechanism in operation moves from a first position to second position when the at least one solenoid is activated;
- and
- a hydraulic pressure system operably connected to the latch mechanism, the hydraulic pressure system in operation moves the latch mechanism from the second position to the first position using hydraulic pressure from a hydraulic fluid, when the at least one solenoid is deactivated, wherein the hydraulic pressure system is located within the housing,
- wherein the hydraulic pressure is relieved when the latch mechanism is in the first position.
A method of retracting a ram air turbine actuator, comprising:
- moving a latch mechanism from a second position to a first position using hydraulic pressure from a hydraulic fluid;
- wherein the latch mechanism locks the ram air turbine actuator in a retracted position when the latch mechanism is in the first position;
- wherein the hydraulic pressure is relieved when the latch mechanism is in the first position.
A method of manufacturing a ram air turbine actuator, comprising:
- forming an actuator housing;
- installing at least one solenoid in the actuator housing;
- installing a latch mechanism in the actuator housing;
- operably connecting the latch mechanism to the at least one solenoid, the latch mechanism in operation moves from a first position to second position when the at least one solenoid is activated;
- and
- operably connecting the latch mechanism to a hydraulic pressure system, the hydraulic pressure system in operation moves the latch mechanism from the second position to the first position using hydraulic pressure from a hydraulic fluid, when the at least one solenoid is deactivated, wherein the hydraulic pressure system is located within the housing.
