Novel efficient wing buoyant aircraft design for enhanced aerodynamic performance

The current research aims to design a novel concept for an efficient wing buoyancy assisted aircraft (EWBA) by investigating the optimum aerodynamic efficiency of next-generation aircraft features; this EWBA is entirely different from a current traditional airship and aircraft. In the relevant literature, very little attention has been paid to optimising the design features by computational design point methods case of an airship. The 3D model of 6:1 prolate spheroid, tail hull, straight wing hull, and efficient wing buoyant airship (EWBA) was designed in Solidworks after several iterations. Then, the pressure- base ANSYS Fluent (Ansys 16.1) solver was successfully employed for investigating the aerodynamic performance of efficient wing buoyant airship (EWBA), planner wing, and tail hull airship and compared its aerodynamic parameters; namely the lift coefficient, drag coefficient, and lift to drag ratio by using the Reynolds-averaged Navier-Stokes (RANS) governing equation (k-ε) and the RSM model.
