摘要： A quenching agent delivery apparatus is provided for delivering a quenching agent to a component to be quenched. The delivery apparatus comprises an inlet through which the quenching agent is configured to be delivered into the apparatus, a first outlet configured to deliver quenching agent in a first direction to an inner surface of the component, and a second outlet configured to deliver quenching agent in a second direction to an inner surface of the component.

摘要： A disclosed controller is configured with logic that, when executed, performs actions to extend landing gear of a maglev vehicle. The actions include receiving a height control target value and transitioning between a standby control state and an active control state. The controller maintains the landing gear in a fixed position when the controller is in the standby control state, and the controller controls extension and retraction of the landing gear according to the height control target value when the controller is in the active control state.

摘要： A passive lateral stability system maintains the position of a vehicle relative to a guideway. The system includes first and second guide assemblies that urge the vehicle away from first and second electrically conductive guide walls, respectively. The first guide assembly includes a wheel configured to reciprocate toward and away from the first guide wall. A biasing element bias biases the wheel toward the first guide wall. The system further includes a magnetic element associated with the wheel, wherein movement of the magnetic element relative to the first guide wall produces a magnetic force that biases the wheel away from the first guide wall. A second guide assembly is mounted to the vehicle and urges the vehicle away from the second guide wall.

摘要： A pin for a pinned joint includes a hollow body with a first and second end caps coupled to first and second ends, respectively. The body and the end caps at least partially define a cavity within the body, wherein at least one aperture extends through the hollow body. A main piston is slidably disposed within the cavity and divides the cavity into a first chamber proximate to the first end and a second chamber proximate to the second end and fluidly isolated from an environment around the body. A lubricant is disposed within the first chamber. The main piston moves toward the first end of the body when a pressure in the second chamber is greater than a pressure of the environment. Movement of the main piston toward the first end of the body discharges lubricant through the at least one aperture.

摘要： Techniques and methodologies for servicing a shock strut are provided that account for the variability in gas solubility of the shock strut while in-service. These examples incorporates knowledge of the shock strut's stoke history in order to estimate/predict the amount of gas in solution, its percentage saturation, etc. This may permit a more refined knowledge of the true servicing state of the shock strut.

摘要： A method of determining a service interval for an actuator of a landing gear assembly is suitable for used with a landing gear assembly in which the actuator positions the landing gear assembly between a stowed position and a deployed position. The method includes the steps of determining an actuator travel value for a time interval and increasing a total actuator accumulated travel value by the actuator travel value for the time interval. The method further includes the step of comparing the total actuator accumulated travel value to a predetermined value.

摘要： A maglev system includes a maglev vehicle that reciprocates between a levitated state and a non-levitated state. The vehicle includes a capsule supported by a first left wheel and a corresponding first right wheel when the vehicle is in the non-levitated state. The system further includes a track having a left rail and a right rail, each of the left and right rails having a plurality of plates arranged in series. Proximate ends of adjacent plates define a joint. Each rail provides a support surface that the first left and right wheels rollingly engage when the vehicle is in the non-levitated state. The joints of the left rail are offset in a longitudinal direction from the joints of the right rail.
