Abstract: 

In this paper conceptual design and optimization of gliding parachute configuration are discussed. To this end, a design cycle is planned for conceptual design procedure and an optimization-based design approach is established to provide an integrated design algorithm for gliding parachute platforms. The optimization problem is formulated with a cost minimization approach which is constrained by static stability and safe landing velocity as design criteria. The parachute configuration is defined with minimum required parameters and aerodynamics, stability and performance characteristics are provided based on a semi-theoretical approach. Hence, a computational software is incorporated with theoretical approximations to provide the required disciplinary dataflow in the design cycle. The significant design parameters are verified by available wind tunnel test data. Optimization problem is solved using genetic algorithm method whereas constraints are handled by penalty function approach. Trim points are obtained like an all-at-once approach through a simultaneous analysis and design algorithm. Finally, as a case study, optimized configuration is achieved for a real gliding parachute. Results show a fair estimation of parachute characteristics along with the reduction in manufacturing cost for new configuration up to 25%.
