Drag Polar Given By Coefficient Of Lift Calculator

The drag polar is a graphical representation of aerodynamics that illustrates the relationship between an aircraft’s lift coefficient () and its drag coefficient (). It provides valuable insights into the aircraft’s aerodynamic performance by displaying how drag varies with changes in lift coefficient. However, the relationship between lift coefficient and drag coefficient can be described by the following equation, which represents the drag polar: 

Where:

  • is the total Drag coefficient,
  • is the zero-lift drag coefficient (parasite drag coefficient),
  •  is the lift coefficient,
  • K is the Constant (K=1/pi*e*AR).
