| Popis: | In the present study, a muffler for a 40 mm medium caliber gun is designed and manufactured. A muffler is composed of holes, blades and several spaces in the tube. Computational fluid dynamics (CFD) was performed before firing test, and the results were validated by comparing them to the test results. Numerical analysis is examined by analyzing of CFD. In conclusion, CFD was successfully applied to a muffler design. As the results of CFD and field test agreed well on the noise level. The results of test also indicated that a noise reduction about 10 dB and the muzzle velocity was almost equivalent regardless of with or without muffler. |
