Propeller blade station numbers increase from which point?

Tip to hub
Hub to tip
Root to tip
Hub to root

The correct answer is: Hub to tip

The correct choice indicates that propeller blade station numbers increase from the hub to the tip. This numbering convention is crucial for understanding the geometry of propeller blades. The hub is the central part of the propeller that attaches to the engine, and as you move outward towards the tip of the blade, the blade's characteristics can change significantly, including pitch and shape. The station numbers provide a way to reference specific locations along the blade for maintenance, performance analysis, and manufacturing. Understanding this progression is essential for technicians and engineers when discussing design specifications, performance characteristics, or conducting inspections. Knowing that station numbers start at the hub and increase towards the tip helps ensure clarity and precision in technical communication about the propeller's design and performance.
