Portable Prime Power for Directed Energy Weapons

As mobile solid-state RF and millimeter wave sources continue to revolutionize non-lethal weapons there is a growing requirement for small, light-weight, prime power systems capable of producing large amounts of power in very short but numerous timeframes. Phase I will focus on defining how our proposed prime power system will meet or exceed the following performance metrics: 1) power output between 150 kW and 250 kW; 2) JP8 fueled; 3) fuel efficiency of 210 kW/kg; 4) wide ambient operating conditions; 5) total weight less than 250 lbs; 6) output voltage of 345 VDC; 7) power volume density greater than 36 kW/ft3; and 8) power weight density greater than 400W/lb. Our baseline generator head efficiency currently exceeds 96 percent efficiency and each power system component/assembly has been certified for altering operation between full load for 5 minutes and quarter load for 55 minutes over a 4 hour duty cycle. The feasibility for our proposed turbine to meet the ADT and RF system power requirements defined above will be compared to conventional motor generator sets and rotating storage machines. Our ultimate concept definition will include specific power density tradeoffs in watts per pound, architecture tradeoffs to minimize volume, and average power capability as a function of ambient conditions. A comprehensive Phase II development plan with performance goals and key technical milestones that address critical technical risk reduction issues will be prepared. During Phase II a working prototype of the selected concept will be demonstrated with the appropriate prime power system trade-offs identified in preparation for Phase III transition through Joint Non-Lethal Weapons and other Program Office sponsorship.
