Cooling/Thermal Management System Development for Active Denial Technology (ADT) and High-Power Radio-Frequency vehicle Stopper (RF) Systems

The heat exchanger in the Nacelle of the V-22 Osprey cools gearbox oils and hydraulic oil. In operation, the current heat exchanger becomes clogged with sand and dust and the engine overheats. Also, the current unit is very difficult to clean. A micro tube heat exchanger with large air passages offers the potential to alleviate this problem. In this program, Mezzo will design and manufacture, and test a drop in replacement micro tube heat exchanger that will meet thermal performance targets while being far less susceptible to the adverse effects of sand and dust ingestion. The program will also complete fundamental structural tests (shock and vibration, etc.) to demonstrate that the unit, while providing benefits in terms of anti-fouling characteristics, is also rugged.
