Abstract

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.

Description

Background technique [0001] Many types of aircraft, including small business jets, use a dynamic braking system as the primary braking device for the aircraft. In order to solve the unexpected failure of the dynamic braking system, a non-dynamic redundant braking system is usually provided. One such redundant braking system includes a modulating emergency / parking brake valve in combination with an accumulator powerplant. The brake valve may direct pressurized fluid (eg, hydraulic or brake fluid, compressed air, etc.) from an accumulator to apply braking of the aircraft in the event of a failure of the primary braking system. In addition to providing emergency braking, the brake valve fully engages the brakes for extended periods of parking. [0002] Typically, a lever or other actuated mechanism in the cockpit is mechanically connected to the brake valves to control the flow of pressurized fluid in the aircraft's hydraulic system to and from the brake cylinders at the wheels...
