Is that a 3 blade prop and a 4 blader?

Very interesting, especially as the 3-view drawing shows a mix of 3 and
4-blade props. I wonder why this would be? Regards Syke |

Regards Syke The two inner engines were fitted with four-bladed reversible pitch propellers; the outer engines had standard three-bladed feathering props REF: Bridgeman, Leonard.

Just as a wild guess... It may be that the outboard engines get shut down in flight? Seaplanes need a LOT of power to get off the water. But not that much for cruise. |
