Light-weight Vehicle Exhaust System for Amphibious Vehicles

The USMC is interested in the development of an improved exhaust system that can withstand repeated heating/cooling cycles and not suffer performance degradation including corrosion when exposed repeatedly to quenching with ambient temperature sea water, while minimizing the transfer of heat from engine exhaust to the external surface of the vehicle for personnel safety. Triton proposes to optimize its design, further the analysis, and build/develop a lightweight and durable exhaust system using a high temperature composite material system. The system will be less expensive to acquire while still meeting performance specifications and being robust enough to withstand the demanding operating environments. The exhaust system concept minimizes the thermal transfer from the hot exhaust gases to the external surfaces.
