ABSTRACT
This chapter identifies the main environmental and performance requirements for high- temperature electronics to be used in High Speed Civil Transport (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. It addresses important aircraft subsystem high-temperature electronics applications, the temperature range in which electronics will be expected to operate if they are to be un-cooled, and a description of wide-bandgap (WBG)-high-temperature electronics (HTE) components desired for use on military aircraft. The chapter describes the various "components" that can be combined to form a comprehensive thermal system. The internal starter generator (ISG) power is fed to a fault-tolerant power management and distribution (PMAD) electronics network that drives all aircraft electrical subsystems. In the More Electric Aircraft (MEA) architecture, conventional hydraulic-driven flight control actuators will be replaced with electric motor driven actuators and a distributed flight control (DFC) electrical system.
