Jet noise modeling method, jet noise analyzing method,and aircraft designing method |
摘要 |
A jet noise source modeling method of creating a jet noise source model, includes: setting a plurality of point sound sources by quantizing a strength distribution of a jet noise source determined through an analysis of a jet stream and determining respective sound source strengths of respective point sound sources; and determining respective phases of the respective point sound sources based on a known noise level of a far free sound field related with the jet stream. An aircraft having an airframe capable of insulating the interior thereof from noises is designed on the basis of the results of the analysis. |
