Delphinus: Innovative Fin Designs in Rocketry

In rocketry, rocket fins are essential parts that guarantee stability, maximize aerodynamic performance, and enable precise control. This study examines how the materials, forms and locations of fins affect important performance parameters like flight time, altitude and stability of Class-I model rockets. Delphinus, innovative fin designs were created and examined using OpenRocket simulations and practical testing. These included freeform fin shapes laser-cut from lightweight, environmentally friendly materials like balsa wood. The results show that the rocket can reach altitudes of over 1,380 meters due to optimal fin designs, well-placed fins and lightweight materials that greatly reduce drag and improve stability. Additionally, by highlighting sustainability through biodegradable materials, this study highlights the commercialization possibilities of innovative fin designs in educational and recreational industries. In addition to enhancing rocketry performance, these developments support environmental objectives and encourage creativity in aerospace education and business. This effort is a first step in creating high-performance, reasonably priced rocketry systems that strike a balance between sustainability and technological advancement. By offering affordable, high-performing fin designs appropriate for educational programs, hobbyists and aerospace enthusiasts, this research highlights the commercialization possibilities. Both performance-focused and educational applications are supported by the designs' adaptability, which gives professionals and students the chance to experiment with cutting-edge rocketry ideas. Additionally, the project's creative methodology encourages the development of technical skills, creativity and critical thinking—especially in STEM education. Enhancing national competitiveness in international markets, encouraging environmental behaviors and developing aeronautical technology are some of the wider societal effects. By bridging the gap between inventiveness and pragmatism, this work inspires the upcoming generation of scientists and engineers and opens up new opportunities for rocketry development.
