The part of the hub assembly to which the rotor blades are attached is commonly known as what?

• A. Blade Grip
• B. Blade Root
• C. Blade Span
• D. Blade Tip

Answer: (A)

In a helicopter rotor system, the blade grip is the part of the hub that clamps the blade and provides the mounting point for the blade to attach to the hub, transmitting loads and allowing pitch changes. The blade root is the end of the blade itself that fits into the grip, not the hub component. Blade span and blade tip refer to the blade’s length and far end, not the attachment point on the hub. Because the question points to the hub component that actually holds and integrates the blade into the rotor system, the blade grip is the correct term.
