Electric Thrust Control System for Supersonic Transport Power Plant 700819

The design of the propulsion control system for the Supersonic Transport (SST) is a culmination of three years of design trade studies. An analysis was made of the throttle systems of the Boeing 747, XB-70, Concorde and other airplanes with a view toward the applicability of these systems for use on the SST. The major considerations that led to selection of a redundant channel electro-hydraulic propulsion control system are: safety, operational-reliability, performance and weight. Presented here is a description of the SST Propulsion Control System which is composed of two subsystems, the Thrust Control Subsystem and the Mode Control Subsystem.
