The Requirements for High Temperature Electronics in a Future High Speed Civil Transport

High temperature electronics can significantly contribute to the performance of the HSCT primary control system, thus to its economic viability, by reducing wiring weight, electromagnetic and radio frequency interference, connector count, and measurement noise. This paper identifies the main environmental and performance requirements for high temperature electronics to be used in HSCT propulsion and flight control subsystems, and presents a proposed HSCT development schedule to provide insight into the program time available for the development of high temperature electronics.
