This formula uses 4 Variables

Variables Used

Induced Drag Coefficient - The Induced Drag Coefficient is a dimensionless parameter that describes a relation between the coefficient of the lift and the aspect ratio.
Induced Drag - (Measured in Newton) - Induced Drag is caused by that element of the air deflected downward which is not vertical to the flight path but is tilted slightly rearward from it.
Free Stream Dynamic Pressure - (Measured in Pascal) - Free Stream Dynamic Pressure is the kinetic energy per unit volume of fluid at some distance from the body where the density and velocity are freestream values.
Reference Area - (Measured in Square Meter) - The Reference Area is arbitrarily an area that is characteristic of the object being considered. For an aircraft wing, the wing's planform area is called the reference wing area or simply wing area.

Do winglets reduce induced drag?

Winglets increase an aircraft's operating efficiency by reducing what is called induced drag at the tips of the wings. An aircraft's wing is shaped to generate negative pressure on the upper surface and positive pressure on the lower surface as the aircraft moves forward.

How to Calculate Induced Drag Coefficient?

Induced Drag Coefficient calculator uses Induced Drag Coefficient = Induced Drag/(Free Stream Dynamic Pressure*Reference Area) to calculate the Induced Drag Coefficient, The Induced Drag Coefficient formula calculates the coefficient for the induced drag which has been caused due to the element of the air deflected downward which is not vertical to the flight path but is tilted slightly rearward from it. Induced drag results from lift generation by an aerodynamic body, creating vortices at wingtips that induce a downwash, tilting airflow downward and producing drag-opposing motion. Induced Drag Coefficient is denoted by C_D,i symbol.

How to calculate Induced Drag Coefficient using this online calculator? To use this online calculator for Induced Drag Coefficient, enter Induced Drag (D_i), Free Stream Dynamic Pressure (q_∞) & Reference Area (S) and hit the calculate button. Here is how the Induced Drag Coefficient calculation can be explained with given input values -> 0.044182 = 101/(450*5.7).

FAQ

What is Induced Drag Coefficient?

The Induced Drag Coefficient formula calculates the coefficient for the induced drag which has been caused due to the element of the air deflected downward which is not vertical to the flight path but is tilted slightly rearward from it. Induced drag results from lift generation by an aerodynamic body, creating vortices at wingtips that induce a downwash, tilting airflow downward and producing drag-opposing motion and is represented as C_D,i = D_i/(q_∞*S) or Induced Drag Coefficient = Induced Drag/(Free Stream Dynamic Pressure*Reference Area). Induced Drag is caused by that element of the air deflected downward which is not vertical to the flight path but is tilted slightly rearward from it, Free Stream Dynamic Pressure is the kinetic energy per unit volume of fluid at some distance from the body where the density and velocity are freestream values & The Reference Area is arbitrarily an area that is characteristic of the object being considered. For an aircraft wing, the wing's planform area is called the reference wing area or simply wing area.

How to calculate Induced Drag Coefficient?

The Induced Drag Coefficient formula calculates the coefficient for the induced drag which has been caused due to the element of the air deflected downward which is not vertical to the flight path but is tilted slightly rearward from it.
