Which term describes the alignment of blade tips so they pass through the same plane of rotation?

• A. Blade Track
• B. Blade Stall
• C. Blade Flap
• D. Blade Grip

Answer: (A)

Blade track is the alignment of the rotor blade tips so they pass through the same plane of rotation. When blades are tracked correctly, each blade sweeps through the rotor disk in the same plane, reducing periodic vibration and uneven lift that occur if one blade is ahead or behind in the plane. This alignment keeps the rotor system smooth and efficient. Blade stall describes an aerodynamic condition where the airfoil stalls due to an excessive angle of attack, causing loss of lift. Blade flap refers to the up-and-down movement of a blade about its hinge in response to aerodynamic forces. Blade grip is the structural component that attaches the blade to the rotor hub and allows pitch changes. The term that specifically describes aligning blade tips in a single plane is blade track.
