Abstract
Currently, there is a high increase in production of air vehicles equipped with low-power internal combustion engines. The main demasking factor of such engines is the high noise of their exhaust system. To solve this problem, we made a test bench on which we estimated the efficiency of several alternate designs of mufflers. In the course of work, we studied the influence of various internal elements of the muffler on its hydrodynamic resistance and noise attenuation efficiency. According to the results obtained, we found the best design alternate design of the muffler, which effectively coped with its role.
