ULTRA LOW COST ENGINE CONTROL SYSTEM

PRESENT TURBOJET ENGINE CONTROL SYSTEMS, WHICH ARE COMPRISED OF: CONTROLLER, FUEL METERING DEVICE, SENSORS, CONNECTORS, AND HARNESSES ARE THE SINGLE MOST EXPENSIVE SUBSYSTEM ON EXPENDABLE TURBOJET ENGINES. THE SIZE AND COST OF EXPENDABLE TURBOJET ENGINES HAS STEADILY DECREASED. HOWEVER, THE ENGINE CONTROL SYSTEM COST HAS RE MAINED RELATIVELY CONSTANT. ELECTRONIC CONCEPTS PROPOSES TO DEMONSTRATE THAT SIGNIFICANT COST REDUCTIONS CAN BE REALIZED IN EXPENDABLE TURBOJET ENGINE CONTROL SYSTEMS BY: 1) APPLYING HIGHLY INTEGRATED CIRCUIT TECHNOLOGY, 2) UTILIZING A DERIVATIVE OF AUTOMOTIVE FUEL METERING TECHNOLOGY, AND 3) BY INTEGRATING THE CONTROL ELECTRONICS, ENGINE SENSORS AND FUEL METERING DEVICES INTO A SINGLE ENCLOSURE THUS ELIMINATING EXPENSIVE HARNESS AND ELECTRICAL CONNECTORS. SUCCESSFUL COMPLETION OF THIS PHASE I EFFORT WILL LAY A FOUNDATION FOR A PHASE II FLIGHTWEIGHT ULTA LOW COST ENGINE CONTROL SYSTEM. AN ULTRA LOW COST ENGINE CONTROL SYSTEM AND ASSOCIATED TECHNOLOGY CAN BE DIRECTLY APPLIED TO COMMERCIAL AND MILITARY TURBINE ENGINE POWERED GROUND START CARTS, POWER GENERATING UNITS, AND AIR CONDITIONING CARTS. IN ADDITION, A MAJORITY OF AIRCRAFT AUXILIARY POWER UNITS (APU'S) ARE POWERED BY SMALL TURBINE ENGINES WHICH REPRESENT AN IDEAL APPLICATION FOR ULTRA LOW COST ENGINE CONTROL SYSTEMS.
