It would be nice if some aero engineer would show up and empty this bucketful of propwash.
I'm no authority, but once the plane is at cruise, consider this: Imagine that the prop is a SCREW... an AIR SCREW. Imagine the air as a block of wood and the air screw is being screwed into this block of wood. If it has a pitch of 50 inches, the screw will travel 50 inches per revolution..... except for slippage that has been touted to be 3%. This 3% slippage might be considered propwash when at cruise, but the rest of this is just plain (plane) wrong in my book. If we go back to the boat analogy, the BOAT HULL makes the wake.... NOT THE PROP. If you tie the boat to the dock where is it immovable... IS THERE A WAKE? NO !!! The prop blast hardly ripples the pond!!!! BTW... the bigger the plane the bigger the wake. Follow a JET airliner in too close sometimes and see what happens. BIG Jets don't have propwash, but they do have BIG WAKES. Come on guys n' gals. There are forces at work, but.... Let's not get caught up in this line of thought.
