Abstract

At present, only hand-full of research work on design and development of wingsuit exists in the open domain and "sew and fly" approach is still used. In this study, CAD software Solid works was used to design the wingsuit model, using a Gottingen 228 airfoil of aspect ratio 1.05. Ansys Fluent solver was utilised to solve the Reynolds Averaged Navier-Stokes (RANS) equations with a k-#x3C9; turbulence model. In this study the wingsuit is assumed to be flying at a free-stream velocity of 40 m/s. Detailed simulations were recorded at different angles of attack till stall angle to give an insight into the flow dynamics of the wingsuit. Computations showed that the wingsuit had a maximum lift coefficient of 2.4 and reached a stall angle of 40 degrees. The results were compared with the experimental and CFD results of existing literature in the open domain. The non slender delta wingsuit performs extremely well giving a lift coefficient of 2.4 and C_L/C_D of 6.7. The results were validated by comparing them with flat plate results of AR 1.0 and non slender cropped delta wing results of existing literature. A good agreement in terms of trends was obtained for C_L and C_D which indicates that proposed wingsuit should perform well aerodynamically under typical wingsuit flying conditions.
