The relationship of the blade tips in the plane of rotation; blades that are in track move through the same plane of rotation is called?

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

Answer: (A)

Blade track describes how the rotor blade tips move in the plane of rotation. When blades are in track, each blade passes through the same plane, so the tips sweep through one common path as the rotor turns. This alignment helps minimize vibrations and ensures even lift from each blade as it passes through the disk. Blade tracking is checked and adjusted with specialized tools or procedures to bring any out-of-plane blade back into that common plane. For context, blade flap refers to the vertical motion of a blade about its hinge due to aerodynamic forces, blade grip is the hub mechanism that attaches the blade to the rotor, and blade stall is the aerodynamic stall of the blade airfoil.
