Aircraft flight control device particularly for helicopter

摘要

The flight controller has multiple command generation systems (A1-An) and multiple servo-systems (B1-Bp), which receive flight data and flight control instructions. Each of the command generation systems generate a set of commands to direct operation of the flight control surfaces, and one at least of them performs a self-monitoring operation and generates corresponding monitoring signals. Each of the servo-systems has a selector (S1-Sp) which receives the data from the control surfaces and also the control commands. The selector operates under a set priority system, and takes account of the monitoring signal, automatically blocking any system that indicates a fault.
