High Temperature Full Authority Digital Engine Control (FADEC) System

Scientific Monitoring, Inc. (SMI) is developing reliable, high temperature capable, full-authority, digital engine controls technology. Specifically, SMI is developing an innovative system on chip (SoC) capability that will accomplish two major objectives. First, for engines with modest control requirements, for example those with less than six (6) controlled variables, SMI’s approach will provide a SoC, high temperature capable, “mini-FADEC” solution. Second, for larger engines, i.e. those with as many as 17 controlled variables, SMI’s approach will provide a high temperature, distributed system solution. SMI’s distributed system incorporates time-triggered fault tolerant communications with multiple high temperature SoC processors acting as “concentrators.” The proposed technology is thus both flexible and powerful and can be configured to meet the control requirements of varying complexity. This FADEC technology will be applicable to both future propulsion systems in the VAATE perspective, for UAV’s and for legacy and helicopter engines. BENEFIT: The anticipated benefits of the proposed technology include a substantial reduction in the size, weight and volume of electronic turbine engine controls. The proposed technology will also work in 235C environments significantly reducing or eliminating the need for fuel cooling. The distributed architecture enables cost reduction through the use of modular components and "plug and play" compatibility.
