Which measurement describes blade span?

• A. Chord
• B. Blade Span
• C. Pitch
• D. Span from hub to tip

Answer: (B)

Blade span is the distance from the hub to the tip of the blade, essentially the blade’s length or radius. This is the measurement that directly names the extent of the blade itself, which is why it’s the best answer: it uniquely identifies the dimension describing how far the blade reaches from the center to the tip. Chord refers to the blade’s width at a given station, not its overall length. Pitch is the blade’s angle of attack relative to the plane of rotation. Span from hub to tip describes the same physical distance, but the standard term used to label that measurement is blade span.
