LIGHTWEIGHT REMOTELY PILOTED VEHICLE ENGINE ALTERNATOR/STARTERS

INERTIAL MOTORS PROPOSES TO DEVELOP A LIGHTWEIGHT STARTER/GENERATOR FOR UAV/RPV USE FROM AN EXISTING HIGH TORQUE HOLLOW ROTOR MOTOR DESIGN OF 12 LBS. CURRENTLY CAPABLE OF PROVIDING 7000 OZ-IN OF STARTING TORQUE FOR UP TO 30 SECONDS, AND GENERATING 2.52 KW OF POWER FOR > OR - 1000 HOUR LIFE, AT 28 VDC. INERTIAL MOTORS WILL CUSTOMIZE THE 4" BY 6.61" UNIT TO OPTIMIZE TOTAL WEIGHT TO APPROXIMATELY 8 LBS., ACHIEVABLE BY CONSTRUCTING THE UNIT OF LIGHTWEIGHT MATERIALS IN ALL AREAS NOT REQUIRING MAGNETIC FLUX CONDUCTANCE, AND REDESIGNING THE ROTOR TO CONTAIN SUBSTANTIALLY LESS ENCAPSULATION MATERIAL. THE ROTOR WINDING IS SELECTED TO MEET THE REQUIRED SPEED FOR THE OUTPUT POWER REQUIRED FOR THE MOST EFFICIENT POWER MATCH. THE PROPOSED STARTER/GENERATOR HAS EXTREMELY LOW INDUCTANCE AND A METALLIC CONDUCTION SILVER GRAPHITE BRUSH SYSTEM; THEREFORE, THE SYSTEM GENERATES NO EMI/RFI EMISSIONS TO IMPAIR ONBOARD. SENSOR/COMMUNICATIONS OPERATION OPTIMAL DESIGN TRADE-OFFS DURING BENCH TESTING BETWEEN REQUIRED TORQUE FOR ENGINE STARTING AND OUTPUT POWER REQUIRED FOR RPV SENSOR SYSTEMS, WILL PERMIT DESIGN TO BE OPTIMIZED FOR 3 KW OPTERATION. THE GENERATOR, CURRENTLY, CAN OUTPUT 9 KW FOR 30 SECONDS WITHOUT BURNING UP.
