Electronic Control and Monitoring of Aircraft Secondary Flying Controls Available to Purchase

DOWTY ROTOL has recent experience in the design, manufacture and testing of two different electronically controlled wing trailing edge flap high lift actuation systems — one for the British Aerospace B.Ae.146 aircraft and the other for the Construcciones Aeronatuicas/Nurtania CN.235 aircraft. This paper discusses the application of electronics to control and monitor these systems. The resulting equipment is described and the two systems are compared for complexity, type of electronic architecture and reliability.
