Multi-axis serially redundant single channel, multi-path fly-by wire flight control system

摘要

A multi-axis serially redundant, single channel, multi-path fly-by-wire control system comprising: serially redundant flight control computers in a single channel where only one “primary” flight control computer is active and controlling at any given time; a matrix of parallel flight control surface controllers including stabilizer motor control units (SMCU) and actuator electronics control modules (AECM) define multiple control paths within the single channel, each implemented with dissimilar hardware and which each control the movement of a distributed set of flight control surfaces on the aircraft in response to flight control surface commands of the primary flight control computer; and a set of (pilot and co-pilot) controls and aircraft surface/reference/navigation sensors and systems which provide input to a primary flight control computer and are used to generate the flight control surface commands to control the aircraft in flight in accordance with the control law algorithms implemented in the flight control computers.

1. A multi-axis fly-by-wire flight control system of an aircraft, the system comprising:
at least one flight control surface for controlling a pitch directional axis of the aircraft; at least one flight control surface for controlling a roll directional axis of the aircraft; at least one flight control surface for controlling a yaw directional axis of the aircraft; a plurality of input controls each capable of generating a signal indicative of a commanded position of a corresponding control; a plurality of control paths, each control path controlling at least one of the flight control surfaces and comprising a plurality of flight surface controllers; and a plurality of flight control computers coupled to at least one flight surface controller of each controller path that each generates flight surface commands according to predetermined flight control algorithms in part as a function of the signals, wherein only one of said plurality of flight control computers is an active primary flight control computer at any given time with the remaining computers of said plurality running in standby.
