Abstract
PURPOSE: To reduce the starting vibration of a propeller by forming double wall at the outer wall of the hull of a ship at the forward portion of the propeller via an outboard through a gap provided therebetween and providing a partition plate and projected flat plate in the gap.
CONSTITUTION: A gap 7 is formed at the outer wall 5a of the hull 5 of a ship. Outboards 8, 9 are mounted at the gap 7 to form double wall structure partly at the wall 5a at the forward portion of the propeller. The gap 7 is divided vertically into several stages by partition plates 10. A flat plate 11 is verticall projected from the inner walls of the outboards 8, 9. Thus, the upward stream with vortex from the bottom of the ship flows along the outside of the double wall structure but only parallel stream will flow along the double wall. Accordingly, since the stream flowing along the propeller 6 consists of parallel streams, it can simplify the stream velocity distribution so as to reduce the starting vibration of the propeller 6.
