Manual Aerodynamic Optimization of an Oblique Wing Supersonic Transport

摘要

We use manual methods and an advanced geometry generator to optimize a large wign flying obliquely at M_∞√2. These include the informed, but manual, design of the airfoil sections and a blending of these airfoil Sections to create the wing. A manual tailoring of the wing planform and planform (twist axis) bending are used to Ensure a nearly elliptic load. The lift coefficient and sweep are varied sequentially to arrive at an optimum inviscid Design. The viscous drag is estimated by considering the wing to be a flat plate.
