Description
Coast-Down Aerodynamic Drag Tester is a professional analysis tool designed for automotive engineers, vehicle researchers, and performance-focused enthusiasts.
Based on the coast-down testing method, the app analyzes real-world vehicle deceleration data to estimate aerodynamic drag (CdA) and rolling resistance (Crr) without the need for wind tunnel facilities. It provides engineering-oriented insights using physics-based regression models.
Key Features
• Coast-Down Regression Analysis
Fit deceleration data to physical models and estimate CdA, Crr, and fit quality (R²).
• Configuration Comparison
Compare aerodynamic performance across different vehicle setups or modifications.
• Engineering Tools
Includes air density calculation, data smoothing, grade and wind sensitivity analysis, and drag power estimation.
• History & Engineering Diary
Store test results and document environmental conditions, notes, and conclusions.
• Knowledge Base
Learn the fundamentals, limitations, and best practices of coast-down testing.
Intended Users
• Automotive and vehicle dynamics engineers
• Performance testing and modification enthusiasts
• Technical users interested in real-world aerodynamic behavior
