Abstract

Exhaust systems have a significant impact on performance of the vehicle, from the automotive perspective, to its acoustic signature. The soldier wants all the power available for mobility, yet has to pay attention to the noise signature that can be detected by human and sensor devices. Military exhaust systems are largely influenced by program signature and or detectability requirements, and many requirements are quite the opposite of commercial exhaust systems. With the customization, low manufacturing volumes and tight development timelines, it is difficult to produce a low cost system. GLSV has extensive experience developing complete exhaust systems, beginning with the back pressure simulation through comprehensive design, FEA, CFD, acoustic simulation, prototyping and low volume production. Having produced over twenty five custom exhaust systems for marine, ATV, tactical trucks, and combat vehicles puts us in a market leading position to design and manufacture modular components with a focus on low cost tooling and assembly methods.
