122978 - The Impact of Tail Wing Shape on the Resistance Characteristics for Amphibious Vehicle 

The resistance performance of amphibious vehicles can be improved by installing underwater tail wings. The research on the impact of different hydrofoil wing shapes on the resistance performance for amphibious vehicles can provide a reference for the vehicle designs. For an amphibious vehicle model, five types of hydrofoils (symmetrical hydrofoils NACA0012, NACA0015 and NACA0016, asymmetrical hydrofoils NACA23012 and NACA66-209) were selected as the underwater tail wings of the vehicle body. The numerical calculation of the resistance performance for the vehicle body was carried out based on RANS equation and overset meshing technology. The calculation results of CFD can be reflected the resistance changing rules of amphibious vehicle with different tail wing shapes under the working conditions of 0.43<Fr<1.3. The basic shape of amphibious vehicle tail wing can be determined by comparing the effects of symmetrical hydrofoils and asymmetric hydrofoils on body resistance. A tail wing model with better resistance reduction effect can be obtained by the optimization of the hydrofoil wing shapes. The research results show that the asymmetric hydrofoils has a better effect on the resistance reduction of amphibious vehicle than the symmetrical hydrofoils. The chord length and thickness distribution of the hydrofoils will affect the resistance reduction effect of the tail wings.
