| Abstract: | Low pressure capsules are widely used in mountian medicine and space aeronautics. Air flow noise will be produced in the cource of pressure recovery,and is very high. The capsules must bring passengers comfortable acoustical environment to work in, in addition to offer adequate low pressure conditions. In this paper, the calculation method of aerodynamic parameters and noise abatement project in capsules are presented with an example. |
