Very Low Noise, High Efficiency Muffler Designs for Small UAVs
Agency / Branch:
DOD / NAVY
"The role of small acoustically stealthy UAVs for battlefield operations is identified. The challenges associated with noise reduction for such vehicles is described. Novel approaches to reducing the noise emanating from the engine exhaust using an advancedmuffler are presented. These include custom muffler designs, and matching of the aeroacoustic characteristics of the engine and the muffler for optimum efficiency, while reducing noise. The goal is to develop a lightweight (<100 grams), low volume (<24 cu.in. volume, with a max. feature size of 5 in.), low-cost (
