    摘要： A two-step, self-regulating valve (16) controls gas flow from a gas cylinder (12) in a high pressure system. The valve (16) includes a valve body (24), a piston (26), a plug (28), a valve actuator (34), and a piston actuator (32). The piston (26) is movable within the valve body (24) along an axis between a first and a second position. The plug (28) is movable within the valve body (24) along the axis between a valve closed position, a partially open position, and a fully open position. The valve actuator (34) allows the plug (28) to move from the valve closed position to the partially open position. The piston actuator (32) causes the piston (26) to move from the first position to the second position when a gas pressure in the gas cylinder (12) is less than a setpoint. When the piston (26) moves to the second position, the piston (26) allows the plug (28) to move from the partially open position to the fully open position.

    摘要： A controlled pressure release valve controls the gas flow in high-pressure systems. The valve includes a valve body, a slidable spool, a primary flow passage, a first and second chamber, a first and second spring, a first and second passages, and a valve actuator. The valve body has a gas inlet and a gas outlet and houses the slidable spool. The slidable spool has a first end and a second end, and is slidable between a first position and a second position. The primary flow passage connects the gas inlet and the gas outlet and increases with lineal movement of the slidable spool. The first chamber is located adjacent the first end of the slidable spool and a second chamber is located adjacent the second end of the slidable spool. The sliding spool is biased toward the first position by a gas pressure applied by the second chamber and the second spring.

    摘要： A device for controlling the pitch of a helicopter's rotor blade, the device having a BLDC motor based actuator; and at least one control surface operatively connected to the BLDC motor based actuator. The actuator and the control surface are preferably fully integrated into the interior profile of the rotor blade and are capable of controlling the PFC of the helicopter and improving HHC during operation by reducing noise and vibration. The motor is preferably a high power density motor incorporating rare earth permanent magnets connected to a roller/ball screw or planetary gear set to provide the right combination of force/torque, stroke and frequency.

    摘要： A fan variable area nozzle (FVAN) includes a flexible adaptive segment which defines the fan nozzle exit area. The flexible adaptive segment generally includes a multiple of flexible sections, a linkage and an actuator system to morph the flexible adaptive segment between a converged shape and a diverged shape. The flexible adaptive segments seal an interface between sectors to provide an asymmetrical fan nozzle exit area.
