Multidisciplinary Design Optimization of Missile Configurations and Fin Planforms for Improved Performance
The aim of the research described herein was to develop and verify an efficient optimization-based aerodynamic/structural design tool for missile fin and configuration shape optimization. The developed software, OPTMIS, was used to design several missile fin planforms which were tested in the wind tunnel. Specifically, this paper addresses fin planform optimization for minimizing fin hinge moments, as well as aeroelastic design (flexible fin structures) for hinge moment control. The method is also capable of shape optimization of fin-body combinations with geometric constraints. The inclusion of aerodynamic performance, geometric constraints, and structural constraints within the optimization software facilitates multidisciplinary analysis and design. The results of design studies and wind tunnel tests are described.
