Summary
Research to reduce the drag of supersonic transport aircraft at low speed and cruise (transonic and supersonic), and to assess relevant aerodynamic design methods, is described. The evaluation of the aerodynamic design of three wing configurations by wind-tunnel model testing is described. Results are presented for independent CFD analyses of the optimised wing configurations, and a comparative analysis of results from design, model test and CFD evaluation is presented. It is concluded that aerodynamic design by direct shape optimisation, using Euler multiblock CFD methods, with geometric and aerodynamic constraints, is capable of producing aerodynamic configurations of high efficiency. Target values for L/D at cruise and at low speed were achieved and excellent agreement was obtained with the predicted performance. Major limitations were exposed in current computational and design methods for low speed.
