Abstract
Our next subject will be the ship screw which is upto now the most important device for hydrodynamic propulsion. It consists of a number of helicoidally shaped blades connected to a hub. The number of blades can vary from two upto about six. The hub is mounted on a shaft (figure 3.1) which is rotated by the engine. The blades have to be designed so that at a given rotational velocity, a prescribed thrust is produced which moves the ship with the desired speed. This yields a difficult problem because the screw propeller behind a ship is working in a field of flow which differs from a homogeneous flow for several reasons. We indicate some of these.
