How do propeller blade station numbers progress?

Tip to hub
Hub to hub
Hub to tip
Tip to tip

The correct answer is: Hub to tip

Propeller blade station numbers progress from hub to tip. This numbering system allows for a standardized way to identify and describe specific points along the length of the blade. Starting from the hub, which is the base that connects the blades to the engine, the stations are marked as they extend outward toward the tip of the blade. This method of progression is useful for a variety of maintenance, performance, and design considerations. Each station can represent specific aerodynamic characteristics, structural properties, or performance metrics, which are vital for engineers and technicians during inspections or repairs. The options that suggest a progression from tip to hub or include terms like "tip to tip" do not align with standard practices used in propeller design and analysis, where the hub serves as the reference point for measurements moving outward. Therefore, understanding the hub-to-tip progression is crucial in effectively working with propeller blades in aviation.
