GENERATORS FOR MINIATURE RECIPROCATING ENGINES 1W TO 1KW

A POWER SUPPLY SYSTEM USING A MODEL AIRPLANE TYPE GASOLINE ENGINE DRIVING A POLYPHASE ELECTRICAL ALTERNATOR FOLLOWED BY AN ELECTRONIC RECTIFIER AND REGULATOR IS PROPOSED. THE OFFERED UNIT WILL DELIVER ABOUT 100 WATTS OF HIGH QUALITY DC POWER IN THE 12-15 VDC RANGE. THE GENERATOR WILL BE DESIGNED, CONSISTENT WITH A THEORY OF OPTIMIZATION AS DESCRIBED IN THE PROPOSAL, FOR MAXIMUM RELIABLE OUTPUT FOR A GIVEN PACKAGE ENVELOPE AND WEIGHT. OPTIMIZATION EQUATIONS, UNIFORMLY APPLICABLE TO THE RANGE OF 1 TO 1000 WATTS POWER OUTPUT AS A FUNCTION OF PRIME MOVER SPEED, WILL BE DEVELOPED. THE DESIGN FORMULA, DEMONSTRATED AND VERIFIED IN THE PROPOSED 100 WATT MODEL, WILL BE UNIVERSALLY APPLICABLE TO THE RANGE OF VARIATIONS. THE PROGRAM WILL INCLUDE A BREADBOARD TEST SET AND FULL TEST RESULTS IN A FINAL REPORT. IN CONTEXT OF DUTY CYCLE AND THERMAL CONSIDERATIONS AS THE DESIGN DRIVERS, THE PROPOSED REPORT WILL INCLUDE PRACTICAL GUIDELINES. A TECHNICAL SUPPLEMENT TO THE PROPOSAL PROVIDES BENCHMARK PARAMETERS AGAINST WHICH TO MEASURE PERFORMANCE. ANTICIPATED BENEFITS/POTENTIAL COMMERCIAL APPLICATIONS - MULTIPLE APPLICATIONS FOR A LIGHT WEIGHT, RUGGED AND RELIABLE LOW POWER DC ELECTROMECHANICAL GENERATOR. KEY WORDS - LIGHT, WEIGHT, RUGGED, RELIABLE, DC, ELECTROMECHANICAL, POWER, SUPPLY
