제너레이티브 디자인을 활용한 드론 디자인 개발 연구

With the diversification of applications and roles for drones, significant time and resources are being invested in the design, development, and validation stages to enhance their flight performance. Particularly in the design phase, there is a growing demand for designers with engineering knowledge and skills to improve the performance of drones. In this study, we utilized generative design as a method to derive solutions for drone development, including lightweighting, stiffness enhancement, and reduction of aerodynamic resistance. Based on this approach, we analyzed the process and outcomes of drone design that satisfy design requirements, aiming to explore the effectiveness of employing generative design. The research methodology employed in this study consisted of several steps. Firstly, a theoretical review was conducted to understand the concepts and components of generative design and the drone's concept and structure. Secondly, generative design was utilized to input the design requirements necessary for drone development, and the obtained results were utilized for design development. Thirdly, validation was conducted through interpretive simulations to verify if the finalized design prototypes aligned with the initially set design goals. Lastly, the research findings were synthesized to derive implications and provide suggestions for future research. The research findings revealed that the drone design proposed in the study exhibited excellent stiffness compared to the design objectives, as confirmed through interpretive simulations. Furthermore, the completed drone design achieved approximately 29% weight reduction in the frame compared to the baseline model. Additionally, the iterative process of generating design prototypes and utilizing various outcomes in the development stage to meet the design objectives for lightweighting and stiffness showcased the potential for the evolution of a novel integration process.
