Development of 60 kW Prime Power Generating System for the Next Generation Jammer

Mainstream previously demonstrated a breadboard Prime Power Generation (PPG) subsystem, including ram air turbine, alternator, and ducting mounted in a 480-gallon drop tank. The demonstration was performed in a wind tunnel at sea-level conditions. The original SBIR Phase II design flight condition objective of 280 KCAS at sea level altitude were not representative of a mission profile for an EA-18G with a NGJ Pod. The near-term specific task executed under this program is the development of a prototype PPG system, to be tested in a wind tunnel that can simulate the more representative flight condition objective of 220 knots calibrated airspeed (KCAS) at 25,000 feet altitude. Development will be completed through the detailed design and performance analysis of the systems key components. At the end of the Baseline effort, performance predictions for design and off-design flight conditions will be complete and a full PPG will be fabricated and experimentally demonstrated in a wind tunnel environment and result in a prototype unit at a Technology Readiness Level (TRL) of 4. During the Option portion of the program, Mainstream will complete final wind tunnel testing. Testing will be completed at representative flight conditions, resulting in a prototype at a TRL of 5.
