An investigation into wing in ground effect aerofoil geometry

摘要

SummaryThis paper details experimental results from wind tunnel studies of a DHMTU 12-35.3-10.2-80.12 and NACA 0012 section operating in ground effect. It was found that the drag of theDHMTU 12-35.3-10.2-80.12 increased with decreasing altitude, contrary to expectations andsuperior lift performance to the NACA 0012 baseline section was generated. The DHMTUpossesses superior L/D at low angles of attack when in ground effect. These experimental studieshave illustrated the unique aerodynamic characteristics of the DHMTU 12-35.3-10.2-80.12 andindicated areas for further optimisation of the design of ground effect airfoils.
