- Аннотация: The article considers the problem of optimizing (from the viewpoint of soundproofing capacity)the framework of a reinforced shell under the action of the propeller’s acoustic field. Nonstationary data andthe pressure field from the propeller on the surface were obtained using a software package that implementsan implicit numerical method with a high order of approximation when solving the compressible Euler andNavier–Stokes equations. The vibrations and acoustic radiation of a shell simulating an aircraft fuselage wascalculated using an analytical method for calculating an orthogonally reinforced elastic structure. The framework was optimized by shifting the frames and stringers and varying the height, thickness, and width of theprofile bars
