Pickleball Paddle Aerodynamic Optimization
Multi-Objective Shape Optimization for Drag Reduction
Velocity (m/s): 0 → 25
Optimized paddle geometry showing streamlined edge profile with controlled flow separation across swing angles
Abstract
Comprehensive aerodynamic shape optimization study of a pickleball paddle aimed at minimizing air resistance during swing while maintaining aerodynamic stability. The analysis employed both steady-state and transient CFD simulations with high-resolution meshing to capture detailed flow features around the paddle face and edges.
A multi-objective optimization framework was implemented to explore the design space and identify optimal paddle geometries that balance drag reduction with rotational stability. The optimization revealed that subtle modifications to paddle edge geometry and face curvature significantly influenced flow separation patterns and wake structure.
The aerodynamic optimization study successfully demonstrated significant performance improvements through targeted shape modifications while preserving structural and manufacturing constraints. The combination of steady-state and transient analysis provided comprehensive insights into both time-averaged drag characteristics and dynamic stability behavior.
