| Abstract: |
| One of genetic algorithms, which is established based on real number skill and then combines with aerodynamic analysis through engineering evaluation, is used to carry out aerodynamic single point and multi point designs of aircraft. During the optimization and design, the geometry and relative positions among wing, body and horizontal tail are taken as the design variables. The objective of optimization is to get the highest lift to drag ratio of aircraft as possible at both transonic and supersonic states at trim. The optimization results show that the optimization design method presented here is effective to be employed to carry out aerodynamic configuration design of aircraft with conventional layout. |
