Drag Coefficient Given By Drag Coefficient Of An Airfoil Calculator

In flight mechanics, the drag coefficient (CD) is a parameter that quantifies the aerodynamic drag experienced by an aircraft as it moves through the air. It reflects the efficiency of the aircraft’s shape in reducing air resistance. Determined by factors like design and surface features, minimizing CD is crucial for optimizing aircraft performance and fuel efficiency. The formula to calculate Drag coefficient as follows: 

Where:

  • Cd is the Drag coefficient of an airfoil,
  • CL is the lift coefficient,
  • e is the  Oswald efficiency factor,
  • AR is the Aspect ratio.
