Which part of the blade attaches to the blade grip?

• A. Blade Root
• B. Blade Tip
• C. Blade Stall
• D. Blade Flap

Answer: (A)

The part that attaches to the blade grip is the blade root. The root is the section of the blade that sits near the hub and is engineered to mate with the blade grip, transferring the aerodynamic loads from the blade into the rotor head. It provides the secure connection and structural interface that allows the blade to be clamped or bolted to the hub while still permitting the blade to pivot with the hub. The tip is simply the far end of the blade, not involved in attaching to the hub. Blade stall is an aerodynamic condition that can occur on the blade, and blade flap describes how the blade moves about its hinge, not a connection point. Therefore, the blade root is the correct part that attaches to the blade grip.
