摘要:
A wind turbine energy conversion device that can take advantage of the higher speed and more persistent winds at higher altitudes is hereinafter disclosed. The wind turbine energy conversion device includes an unmanned aerial vehicle (UAV) connected to one end of a tether (which may include multiple shorter tethers), the other end being connected to a terrestrial anchorage point. The UAV flies at altitudes where wind speeds can reach 40 mph or higher. The UAV comprises a flying wing with one or more trailing wind power turbines and flies airborne maneuvers designed to increase relative wind speed up to about four times the true wind speed.

A flight control surface actuator includes a mechanism that enables the actuator translation member to be selectively decoupled from the actuator rotating member. The actuator includes an actuation member, a translation member, an extension member, and a locking member. The actuation member is adapted to receive a drive force and is configured, in response to the drive force, to rotate and cause the translation member to translate. The extension member surrounds at least a portion of the translation member and is configured to be selectively coupled to, and decoupled from, the translation member. The locking member surrounds at least a portion of the extension tube and is movable between a lock position, in which the locking member couples the extension member to the translation member, and a release position, in which the locking member decouples the extension member from the translation member.

An aircraft flight control surface actuation system includes a plurality of electric motors-driven flap actuators, and a plurality of electric motor-driven slat actuators. The motor-driven actuators receive activation signals from flap and slat actuator controllers and is, in response to the activation signals, move the flaps and slats between stowed and a deployed positions. The flap and slat actuator controllers each include a plurality of independent actuator control channels that independently supply the activation signals to the motor-driven actuators.

A health monitoring system for an unmanned underwater vehicle (UUV) is disposed within a submerged docking station. The health monitoring system receive signals representative of performance of the docking station equipment and uses the data to determine the health status of the docking station equipment, to generate health status data representative thereof, and transmits the health status data to a remote station. The health monitoring system also retrieves health status data from UUVs that are periodically docked in the docking station, and transmits this data to the remote station.

An energy storage flywheel system includes a shaft, one or more primary bearing assemblies, and one or more secondary bearing assemblies. A secondary bearing control circuit determines the operability of the primary bearing assemblies and, based on this determination, selectively engages the secondary bearing assemblies to rotationally support the flywheel shaft.

A control valve having an external valve trim adjustor is provided. The control valve comprises a valve shaft comprising a contact member extending in a direction transverse to the valve shaft, a stationary valve cap adapted to receive the valve shaft, an adjustment member coupled to the valve cap, and a stop plate coupled to the contact member and threadedly coupled to the adjustment member, the stop plate positioned at least partially between the adjustment member and the contact member and adapted to position the contact member away from the valve cap in response to manipulation of the adjustment member.
摘要:
An actuator assembly includes a motor assembly, a harmonic drive gearbox, an actuator, and an electromagnet brake device. The actuator assembly is fairly compact in size and the electromagnetic brake device is a non-contact type of devices, making it less prone to wear as compared to many other brake devices.

A flight control surface actuator assembly includes a plurality of flight control surface actuators, and a pivot arm. Each flight control surface actuator is adapted to couple to a flight control surface, and each is further adapted to receive a drive force and is operable, upon receipt thereof, to move between at least an extended position and a retracted position. The pivot arm is rotationally coupled to, and is configured to pivot relative to, each of the flight control surface actuators, the pivot arm is also adapted to be rotationally coupled to, and configured to pivot relative to, a static airframe structure.
摘要:
An object ejection system uses an energy storage flywheel to drive the fluid pump that is used to pressurize the ejection tubes. The energy storage flywheel is periodically spun-up using an electric motor. The energy stored in the energy storage flywheel is used, when needed, to drive the fluid pump and supply pressurized fluid to an impulse tank. The pressurized fluid in the impulse tank is used to eject an object, such as a weapon, from one or more ejection tubes.
