Design, Development, and Flight Test of Multiplexing Hardware for Use in a Fly-by-Wire Flight Control System.

Abstract

C-1147AF-8225AFFDLTR-73-43(*flight control systems, multiplexing), digital systems, electric wire, design, flight testing*fly by wire flight control systemsThe report contains a description of the design, development, airworthiness testing and flight test of multiplexing hardware for use in a fly-by-wire flight control system. The multiplexing concept employed makes use of By-phase Manchester baseband modulation of pulse coded digital data. Each analog value to be transmitted is converted to a digital format serially and transmitted over a twisted-shielded-pair cable. A party line transmission concept was employed to permit two transmitters to share the same transmission line. The air-worthy equipment was used to transmit signals in the fly-by-wire flight control system of the Total In-Flight Simulator (TIFS) aircraft. (Modified author abstract)
