— The article investigates the response of composite skin-stringer joint to broadband acoustic loading. To describe the frequency and spatial structure of the acting sound field, the study used a model of a field completely correlated over the surface of a sample with a uniform frequency spectral density. The finite element method (FEM) was used to simulate the response of the joint in the 50–1550...
A study of the phenomenon of diffraction of acoustic waves in application to the task of noise shielding by the method of maximum length sequences has been carried out. Rectangular plates and an aircraft model of integrated layout are used as the screens. In the study of noise shielding by aircraft model, the theorem of reciprocity is used. A comparison of experimental results with calculations performed...
