Induced Drag is a type of aerodynamic drag experienced by an aircraft as a result of the production of lift. It’s associated with the creation of wingtip vortices and is a fundamental concept in aircraft design and performance analysis.
Formula: The formula for induced drag (Di) is given by:
- Di is the induced drag (in newtons, N).
- Cl is the coefficient of lift (dimensionless).
- ρ (rho) is the air density (in kilograms per cubic meter, kg/m³).
- S is the wing area (in square meters, m²).
- k is a constant related to the aspect ratio of the wing.
- AR is the aspect ratio of the wing (dimensionless).
