摘要： A method for determining a target steering angle for nose landing gear of an aircraft includes receiving rudder pedal input data into a steering control unit, receiving aircraft speed data into the steering control unit, calculating a normal gain, calculating a parking gain, and adding the normal gain and the parking gain to determine the target steering angle. The normal gain is a positive quantity in all aircraft speed and pedal stroke ranges. The parking gain is a positive quantity in parking and taxiing speed ranges. A nose wheel steering system is also disclosed.

摘要： A door opening and closing mechanism for opening and closing the door from the inside of a fuselage. A door pivotally supported at an opening portion of the fuselage includes first and second position restricting links each having one end pivotally supported on the fuselage with a door driving link having one end pivotally supported on the door. The other end of the second position restricting link is pivotally supported on a middle portion of the door driving link. The door opening/closing operation lever is provided at one end with a grip with the other end pivotally supported on the other end of the door driving link. The middle portion of the door opening/closing operation lever is pivotally supported on the other end of the first position restricting link. By pulling the grip toward the inside of the fuselage and thereafter pushing downward, the door can be closed.

摘要： A rudder bias system for an aircraft with a right engine and a left engine includes a component determining a left and right primary and secondary thrust estimates. The system includes a left engine thrust estimate selector determining a left selected estimate based on the left thrust estimates and a right engine thrust estimate selector determining a right selected estimate based on the right thrust estimates. The system includes an enable and mode component determining one or more corresponding validities for the thrust estimates. The system includes a control component generating an engage command based on a thrust differential between the right engine and the left engine, calculated from the left selected estimate and the right selected estimate and a torque command based on an equivalent pedal force assistance calculated as a difference between the thrust differential and an activation threshold.

摘要： According to one or more aspects, a control system for managing operational limits associated with two or more actuators includes a controller. The controller may continually monitor a first operational limit associated with a first actuator and a first operational limit associated with a second actuator. The controller may determine a first overall distributed control system operating limit based on the first operational limit associated with the first actuator, the first operational limit associated with the second actuator, and a type of operational limit associated with both operational limits.

摘要： A door assembly for an aircraft includes a partition panel disposed laterally within a fuselage of the aircraft and a descender panel moveably secured to a lower end of the partition panel for selectively closing an aisle opening defined below the partition panel. The door assembly further includes a handle disposed on the partition panel that is operatively connected to the descender panel through a link mechanism such that rotation of the handle is translated into movement of the descender panel to move the descender panel between a retracted position and a deployed position.

摘要： An aircraft includes a fuselage including a plurality of frame members disposed at predetermined intervals in a longitudinal direction of the fuselage and a plurality of stringers extending substantially linearly in the longitudinal direction. The fuselage defines an aircraft interior. A compartment is located in the interior of the fuselage. The compartment defines an interior area. A first window assembly is mounted to an upper portion of the fuselage for introducing daylight into the interior area. The first window assembly is flanked by adjacent frame members of the plurality of frame members and adjacent stringers of the plurality of stringers. The first window assembly includes a window pane, an inner cover and a retainer. The inner cover introduces daylight from the window pane into the interior area. The retainer secures the window pane and the inner cover to the fuselage.

摘要： A hydraulic system for an aircraft includes a brake operation device, a pressure supply, a reservoir, a shut-off valve, and a wheel brake. The shut-off valve is in fluid communication with and is disposed between the pressure supply and the brake valve. The shut-off valve can include a poppet, a first valve seat and a second valve seat. Movement of the poppet is controlled by operation of the brake operation device. The poppet is movable between a first position where the poppet acts against the first valve seat and a second position where the poppet acts against the second valve seat. In the first position, fluid flow is blocked between the pressure supply and the brake valve through the shut-off valve. In the second position, fluid flow is allowed between the pressure supply and the brake valve through the shut-off valve. The wheel brake is in fluid communication with and downstream from the shut-off valve.
