In general, a deflector is built in a rocket Launch Pad (LP) in order to reduce the influences of exhaust plume on a rocket body. The rocket frame deflector is expected to be a low frequency sound source because of its large dimension. Since the low frequency sound wave is dangerous for rocket body at its natural frequency, it is necessary to make the frequency characteristics of deflector clear. The characteristic frequency analysis of a modeled rocket frame deflector is conducted using a FEM (Finite Element Method) solver. It can be seen from the FEM analysis that the strong resonance occurs at low frequency in the modeled deflector. Three dimensional numerical analysis of sound radiation from deflector including rocket plume inflow is also conducted on a modeled LP using a hybrid code of an Euler flow solver and a Linearized Euler solver. From the sound radiation analysis, the characteristic sound wave from a modeled deflector has low frequency.","subitem_description_type":"Other"}]},"item_5_description_32":{"attribute_name":"資料番号","attribute_value_mlt":[{"subitem_description":"資料番号:
