Abstract
THE PROPOSED EFFORT WILL DEVELOP AN INTEGRAL STARTER/GENERATOR FOR SMALL TURBO JET ENGINES. THE STARTER CAN BE POWERED BY A 28 VDC BATTERY. THE LENGTH OF THE STARTER WILL BE 2.5 - 3" AND THE 0.D. WILL BE 2.5". THE STARTER WILL BE ABLE TO GENERATE 190 OZ-IN OF PEAK TORQUE TO ACCELERATE THE TURBINE TO 50 KRPM. AFTER THE ENGINE RUNS ABOVE SUSTAINING SPEED THE ELECTRONIC CONTROL WILL SWITCH FROM THE STARTER MODE INTO THE GENERATOR MODE. THE UNIT WILL THEN DEVELOP UP TO 1 KW OF REGULATED 28 VDC POWER. THE STARTER/GENERATOR IS A BRUSHLESS HYBRID MOTOR DESIGN. RARE EARTH MAGNETS WILL BE USED TO DEVELOP SUFFICIENT POWER IN THE GIVEN PACKAGE SIZE. PROPRIETARY DESIGN TECHNIQUES ARE USED FOR THE BRUSHLESS MOTOR AND THE ASSOCIATED CONTROL ELECTRONICS TO MINIMIZE THE POWER CONSUMPTION DURING START AND TO MAXIMIZE EFFICIENCY WHEN OPERATING AS A GENERATOR TO MINIMIZE THE FLIGHT PERFORMANCE LOSS OF THE TURBINE ENGINE.
