While momentum theory looks at the fluid as a whole, Blade Element Theory evaluates the local aerodynamic forces acting on individual sections of a rotor blade. ): Increases linearly from the root to the tip of the blade

BET slices a single rotor blade into a series of independent, narrow spanwise segments (elements). Each segment acts as a small, two-dimensional airfoil experiencing its own local aerodynamic environment. Local Flow Variables: Rotational Velocity (
