Overview: computational and experimental research in studying acoustics and acoustic strength of the flying vehicles

The need to improve aviation technology poses complex problems for the engineers. Mathematical simulation is becoming increasingly important in solving them as it expands possibilities in designing a flying vehicle. Noise is negatively effecting human health; therefore, one of the promising areas in modernizing the aviation structures is associated with reducing its level in the flying vehicle cabin. In addition to the fact that noise causes discomfort and has a detrimental effect on the body, acoustic loads could contribute to the fatigue cracks formation in the airframe structure, which is unacceptable. The paper describes main approaches to studying acoustics and acoustic strength both experimentally and using the mathematical simulation. It provides an overview of methods to reduce noise in a cabin. Promising research areas are identified. Literature analysis demonstrates the relevance of using numerical calculation in the design and development of the computation and experimental methods making it possible to reduce the number of full-scale testing.
