摘要： A hydraulic actuator is configured to provide redundant boost control to an aircraft within approximately the same space required by a single hydraulic cylinder. The hydraulic actuator includes a housing and a piston assembly disposed within the housing. The piston assembly includes a ram, a first piston secured to the ram, and second and third pistons disposed on the ram such that the second and third pistons are translatable relative to the longitudinal axis of the ram. The pistons form two hydraulically separate actuator cylinders within the space required by a single cylinder which results in a reduction in the weight and size of the hydraulic actuator.

摘要： A technique provides power-limiting regenerative braking to a utility vehicle. The technique involves detecting that the utility vehicle is moving in a forward direction at a first speed. The technique further involves applying a first regenerative braking power level to the utility vehicle in response to detecting that the utility vehicle is moving in the forward direction at the first speed. The technique further involves detecting that the utility vehicle is moving in the forward direction at a second speed which is less than the first speed. The technique further involves applying a second regenerative braking power level to the utility vehicle in response to detecting that the utility vehicle is moving in the forward direction at the second speed. The second regenerative braking power level is lower than the first regenerative braking power level.

摘要： A laminated elastomeric journal bearing has an outer sleeve having an inner surface, at least a portion of each end of the inner surface being a concave surface of revolution, and an inner sleeve having an outer surface, at least a portion of each end of the outer surface being a convex surface of revolution. Alternating layers of elastomer and metal are located between the sleeves, with adjacent surfaces of the layers and the sleeves being adhered to each other.

摘要： Various implementations directed to managing access for a manufacturing system are provided. In one implementation, a method may include receiving access management request data at an automated provisioning system of an entity. The method may also include determining ready task data based on the received access management request data. The method may further include transmitting provisioning request data based on the determined ready task data. The method may additionally include transmitting status request data after a predetermined amount of time. The method may also include receiving the external status data. The method may further include determining generic status data based on the received external status data. The method may additionally include performing access management operations based on the determined generic status data. The method may also include manufacturing physical components using the manufacturing system based on the access management operations.

摘要： A wing apparatus and aircraft are described providing greater maneuverability and efficiency for vertical takeoff and landing vehicles. Use of a fowler flap is shown in combination with a sliding panel. The sliding panel can nest within a wing similar to a fowler flap. During vertical maneuvers the sliding panel can be moved forward and on top of the wing. This can alleviate download during vertical maneuvers while minimizing drag as forward flight begins.

摘要： An aircraft is described with both VTOL (vertical takeoff and landing) capabilities and convention airplane capabilities. A preferred embodiment comprises a fuselage and fixed wing, with one boom on either side of the fuselage. Each boom comprises a tilt rotor on a fore end and a fixed rotor on the aft end. Both rotors can be directed vertically for VTOL capability. During cruise the tilt rotors can be directed forward for thrust and the fixed rotors can be stopped and directed along the boom axis, minimizing drag. The described embodiments have advantages in weight savings and maneuverability compared to other VTOL aircraft.
