The energy held into the driving shaft is delivered to the propeller where it translates the rotating motion to the forward and reverse movement of the ship’s hull. Precisely, the energy coming from the main engine whether diesel or electric that is manifested on its flywheel is connected to a marine gearbox (if equipped) or directly to the propeller shafting, depending on if an intermediate shaft is needed or only the propeller shaft is installed. The connection built by the tail shaft between the main engine and the propeller also transmits the power (speed and torque) produced by the main engine to the ship’s propellers. This lateral motion is therefore seen as the ship’s movement either ahead or astern. These propellers have various types and forms but the main principle is to have twisted blades that when rotated cause lateral motion on the plane where it is being spun. In general, it serves as a connection between the engine and the drive unit, for boats the drive unit is called the propeller.Ī propeller is a fan-like structure situated underwater and attached to the vessel shafts. The tail shaft is a part of the propulsion system not only in marine but also in automotive and aviation.
