Abstract: As the speed and power of surface ships rise, the reduction of ship acoustic signature and self-noise is becoming an important task of naval engineering. A significant decrease in underwater ...

Abstract: High-payload platforms flying in extreme-ground-effect represent a promising concept for high-speed amphibious transportation. Their dynamics is governed, to a large extent, by unsteady airflow under the platform. A ...

Abstract: Power augmented ram platform vehicle is a high-performance air-assisted amphibious transport of the new generation. The objective of this study is to determine the optimal position of the platform ...

Abstract: The subject of this paper is modeling of low-amplitude acoustic fields in enclosures with nonuniform medium and boundary conditions. An efficient calculation method is developed for this class ...

Abstract: A 32.8-kg unmanned aerial vehicle (UAV) is employed as a case study to assess the accuracy of the empirical techniques used in predicting aerodynamic performance. Despite the prevalent use of empirical methods for the ...
