Contract: M67854-10-C-0002
Award Amount: $600,000.00


The objective of this program is to develop techniques to reduce engine cooling system noise levels of the Expeditionary Fighting Vehicle (EFV). Mezzo's approach is to redesign the engine cooling heat exchangers (LTC, HTC, fuel cooler, and condenser) using Mezzo's heat exchanger technology to reduce the overall heat exchanger pressure drop and thus the demands on the cooling fans. Reduced pressure drop through the heat exchangers translates to reduced fan noise and reduced fan power. In Phase I, Mezzo showed that its heat exchangers could reduce the fan noise by 4dB, reduce the fan power by 38%, and reduce the heat exchanger weight by 170lbs. The goal of the Phase II program is to advance the Technical Readiness Level (TRL) of the LTC/HTC heat exchanger and the Condenser/Fuel Cooler to TRL 6. In Phase II, Mezzo will design, fabricate, and test full-scale drop-in replacement heat exchangers. In the Option period of the program, Mezzo will build 2 LTC/HTC heat exchangers and supply them to the EFV office for vehicle testing. If funding above and beyond the baseline Phase II program is available, Mezzo will advance the condenser/fuel cooler to TRL 6 and build units for vehicle testing.
