🔍 Key Concepts

• Ahead motion and what "upstream" vs. "downstream" mean in terms of water flow around the propeller • Difference between pressure side and suction side of a foil (like a propeller blade or an airplane wing) • How water flows onto a propeller when the vessel is moving ahead

💭 Think About

• When the vessel is going ahead, from which direction does the water approach the propeller: from in front of it or from behind it? Relate that to "upstream" and "downstream." • Think of an airplane wing: which side is the high‑pressure side and which is the low‑pressure (suction) side? Now transfer that idea to a propeller blade moving through water. • Which surface of the blade actually pushes the water astern, and which surface has lower pressure that helps pull the blade forward?

✅ Before You Answer

• Be clear on which way the water flows relative to the propeller during ahead motion before deciding between "upstream" and "downstream." • Decide which side of a propeller blade is commonly called the face (pressure side) and which is called the back (suction side). • Verify whether the back of a propeller blade is associated with higher pressure or lower (suction) pressure as it moves ahead.
