What term refers to the distance from the hub to the tip along the blade?

Explanation:
The distance from the hub to the tip along the blade is blade span. This measures how long the blade extends from the center of rotation to its tip, effectively the rotor radius. Knowing blade span helps gauge the size of the rotor disk and the lift potential. The other terms refer to different blade features: the blade root is the portion that attaches to the hub, the blade grip is the hub component that clamps the blade, and blade track concerns the blade’s alignment within the rotor plane during tracking, not its length.
