What is induced flow?

By Aerodynamics

Induced flow is the downward vertical movement of air through the rotor system due to the production of lift, often referred to as downwash.

What is flapping?

By Aerodynamics

Flapping is the vertical movement of a blade up or down to increase or decrease lift in order to compensate for dissymmetry of lift.

What is coning?

By Aerodynamics

Coning is an upward sweeping angle of the rotor blades as a result of lift and centrifugal force.
