Aerodynamic Optimization of Small Launch Vehicles: Challenges, Design Considerations, and Future Trends

Abstract

This study explores the aerodynamics of small launch vehicles with the goal of enhancing efficiency and minimizing aerodynamic challenges. It delves into various lift and drag principles and the unique challenges faced by small vehicles tasked with carrying satellites into space. The research highlights optimization approaches that can be employed in aerodynamics, which are often difficult to implement due to conflicting design parameters. The findings emphasize the importance of maximizing aerodynamic efficiency to increase payload capacity, reduce launch costs, and improve mission success rates. Key discoveries include the impact of specific design choices on lift and drag forces, as well as maneuvers to address challenges such as shock absorption due to vibrations and preventing vehicle flipping, particularly during the first stage of flight. This research employs both computational fluid dynamics and theoretical analysis to evaluate different configurations and designs, providing valuable insights for aerospace engineers and scientists focused on the development of small launch vehicles. These findings are crucial for advancing innovation within the aerospace industry.
