“…There are many publications that investigate this kind of structures, e.g. the aerodynamics of a WIG craft moving over the curved ground is investigated in [23], a dynamic model of movement in the vertical plane reflecting aerodynamics, hydrodynamics and the driving forces for ground effect vehicles was studied in [13], a complex mathematical model of movement of this type of vehicles was discussed in [4]. In [12], the authors conducted a hydrodynamical study of a wing-in-ground vehicle by towing tank experiments on a given model and CFD numerical calculations.…”

The aerodynamics of powerboats used in inshore powerboat racing has a significant impact on their performance. The aerodynamic drag forces generated on individual elements of this type of boats were tested. The solid model of the boat developed in the CAD software was used for the calculations. The computational grid was generated, as well as the boundary conditions and the turbulence model, were determined. On the basis of such assumptions, the numerical calculations were carried out using the CFD method. The results from the numerical simulations consist of a description of the velocity and pressure distribution around the tested object and identification of the drag force on the components of the powerboat with a description of the relationship between them. Additionally, the variation of the drag force as a function of speed in the range from 0 to 60 m/s was presented. The tests were performed for 5 values of the angle of attack of the boat to the surface of water in the range from 0° to 12°. The scope of the research allowed for the development of a drag force map depending on the defined parameters. The test results can be used to optimize the shape of the boat structure in order to reduce the aerodynamic drag generated on its individual elements.
