ABSTRACT

There is a growing desire to install electronic power and control systems in high temperature environments to improve the accuracy of critical measurements, reduce the amount of cabling and elimination of cooling systems. The use of sensors developed to operate for long periods in high temperature environments allows sensors to be replaced close to the engine sensing and control units eliminating the need for complex heat sinks, special fuel pumping and interfacing, which in turn assists with the goal of aircraft weight reduction. The main advantage of silicon-on-insulator technology in high temperature applications are the reduced leakage current due to the reduced junction area and reduced latch up due to isolated P-type Metal Oxide Semiconductor Logic and N-type Metal Oxide Semiconductor Logic transistors. General Electric (GE) was represented in Clean Sky by GE Aviation Systems and GE Global Research Munich as participants in the High Temperature Survival Electronic Devices for Engine Control Systems project working with Oxford University Materials.
