Evaluation of a Fly-by-Wire System
Abstract
The design of a Fly-By-Wire system is described which is based on applications of active redundancy and electrical feedback techniques. The replacement of mechanical flight control systems with Fly-By-Wire systems for flight control of large high-speed aircraft is advocated because of performance deficiencies in mechanical systems. The Fly-By-Wire system incorporates three redundant channels over which three electrical flight command signals are continuously transmitted to the aircraft control surface power actuator. A breadboard model of one axis of the Fly-By-Wire system was fabricated and evaluated for performance under various failure conditions. Results of the tests demonstrate the feasibility of design techniques with which the three electrical signals are converted to mechanical signals and combined to provide a single input to a hydraulic power mechanism.
