Abstract:
A ground spoiler control architecture for aircraft includes a primary control architecture for providing a roll function, a speed-brake function and a ground spoiler function, and a secondary control architecture for providing the ground spoiler function in the event of a failure of the primary control architecture. The primary and secondary control architectures each include multiple actuators for actuating ground spoilers via independent and redundant signaling paths. Redundant hydraulic accumulators provide pressurized hydraulic fluid to the actuators. A ground spoiler control method includes determining whether the aircraft is on the ground based on the throttle-level-angle and whether any two wheels speeds are active or whether the main landing gear is weighted. Deployment of at least a portion of the ground spoiler panels occurs when and when the main landing gear is on the ground and the aircraft is in a landing configuration based on the throttle-level-angle.
