The Total Drag Coefficient of an airfoil encompasses both profile drag and induced drag, quantifying the overall drag experienced. It’s a dimensionless parameter crucial for assessing aerodynamic efficiency and performance. Total drag coefficient accounts for both viscous and pressure drag components, providing a comprehensive measure of drag forces. The formula to calculate total drag coefficient as follows:
Where:
- Cdf is the skin friction drag,
- Cdp is the Pressure Drag,
- Cdw is the Wind Drag.
