| Abstract: | The noise originated from rocket tank deflation belongs to a kind of aerodynamics noise, which could be above 130dB. This seriously harasses the rocket testing. Basing on practicality, the paper firstly sets forth the principle of diffuser muffler and its design essence, and then according to the deflation parameters, gives out a detailed project which is applied to the related series of rockets. |
