Carrier rocket fairing acoustic vibration test scaling model

The invention relates to a carrier rocket fairing acoustic vibration test scaling model, and belongs to the field of spaceflight. The influence of external noise on the carrier rocket in the flight process is considered. For a full-size model acoustic vibration environment test with high difficulty and high cost, corresponding fairing internal noise and structural vibration control parameters areset according to a similarity principle, a fairing scaling formula is obtained, a scaling model is designed according to the scaling formula, and finally, the sound field characteristics of the full-size model are predicted through the scaling model. The designed scaling model can effectively reflect the sound field characteristics of the original model, and a scaling model test can be used for replacing a full-size model test with high difficulty and high cost in an acoustic vibration environment test, so that the scaling model design method has important engineering significance. 本发明涉及一种运载火箭整流罩声振试验缩比模型，属航天领域。本发明考虑运载
