Lift Off in 2026: Conquer the Theory of Rotary Wing Flight Challenge!

Drag comes in several forms, and one of them is induced drag—the portion of drag that arises directly from the generation of lift. When a rotor blade or wing creates lift, the finite span causes air to spill around the tips, creating wingtip vortices and downwash. This energy loss shows up as a resisting force opposite the flight direction. Induced drag is most noticeable at low speeds or high lift demands (like hover or slow forward flight) and decreases as speed increases, because the downwash effect for the same lift becomes a smaller proportion of the flight speed.

The other terms don’t describe recognized drag types: weight drag isn’t used in aerodynamic terminology; magnetic drag isn’t applicable in this context; aerodynamic lift is a force that acts perpendicular to the motion, not a drag component.
