Abstract or Description

The aerodynamics of multi-axis auto-rotating samara seeds were investigated using a combination of quantitative and qualitative methodologies. The research focused on analyzing flow patterns around these natural structures through wind tunnel experiments designed to clarify their complex aerodynamic behavior. Wind tunnel testing utilized two cameras positioned perpendicular to each other to capture essential flight dynamics. Seeds were released from a fixed height at varying angles and wind speeds to record detailed flight characteristics. Points were marked on every seed to track flight path. Experimental results provide data on descent velocities, angles of attack, and drag for double auto-rotating samara seeds. Despite morphological differences, seed types exhibit similar terminal flight characteristics, primarily influenced by symmetry and aspect ratio. Understanding the aerodynamic intricacies of double auto-rotating seeds offers insight into nature’s optimization strategies for efficient airflow. Applications in aerospace, wind energy, and robotics can benefit from these findings, as engineers draw inspiration from nature’s evolutionary solutions to develop more efficient and agile technologies.
