摘要： An aircraft emergency brake system includes a modulating emergency/parking brake valve in fluid communication with and disposed between a pressure source and a wheel brake and a lever assembly operatively connected with the brake valve. The emergency brake system is operative in first and second stages. The lever assembly includes a handle, a lock mechanism and an unlock mechanism. The handle is movable between a non-actuated position and a fully-actuated position. The brake pressure provided to the wheel brake through the brake valve depends on a position of the handle. The lock mechanism is operatively connected with the handle to obstruct the handle from moving from the first stage to the second stage. The unlock mechanism is disposed on the handle to unlock the lock mechanism allowing movement of the handle to the second stage position from the first stage position.

摘要： A brake handle assembly for an aircraft emergency/parking brake includes a handle movable between a non-actuated position wherein the brake is disengaged and a full actuated position wherein, during movement therebetween, the brake applies a modulated braking force in an emergency brake state. A button actuator is disposed on the handle. Movement of the handle from the intermediate stop position to the full actuated position is obstructed to prevent inadvertent operation of the brake in the parking brake state unless the button actuator is depressed.

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 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.
