School of Engineering Department of Mechanical and Aerospace Engineering 156 Exploring the Aero-Science Behind Flyingsuits Design Supervisor: REDONNET, Stephane / MAE Student: SACHDEVA, Nidhish / AE SHYAMSUKHA, Hrishita / AE Course: UROP1100, Fall UROP1100, Fall This UROP project focused on the computational exploration of wingsuits (also called flying-suits). Upon a previous effort, the computational strategy was further explored by using the two different approaches / solver in Computational Fluid Dynamics (XFL5, ANSYS Fluent). First task consisted in performing various simulations involving a non-canonical airfoil (GM-15), which is closer to wingsuits than traditional ones (e.g. NACA0012). The lift and drag polars obtained were favourably compared with results coming from the literature. In a second time, a 3D wingsuit model was simulated under various flow conditions, delivering early insights about the complex aerodynamic flow features involved. Exploring the Aero-science Behind Flyingsuits Design Supervisor: REDONNET, Stephane / MAE Student: SHYAMSUKHA, Hrishita / AE Course: UROP2100, Summer This UROP project focused on the computational exploration of wingsuits (also called flying-suits). As a continuation of a previous effort, the computational strategy was expanded, this being done by using the STARCCM+ solver. An original 3D wingsuit was designed from scratch, which was then simulated through steady aerodynamic simulations. The computational set-up was first validated through a grid convergence study. Then, various simulations were carried out for a wide range of flow velocities and incidences, allowing to conduct a parametric study of the wingsuit’s aerodynamic characteristics (lift and drag coefficients, etc). Besides, the aerodynamic features entailed by the wingsuit were analysed (e.g., surface pressure distribution, wingtip vortex generation). This allowed highlighting further the intricate physics underlying the aerodynamics of wingsuits. This also made it possible to infer specific design solutions to improve the wingsuit model (e.g. winglets).
