The present invention relates to a high efficiency turbine device. More specifically, the said invention relates to an improvement of a propulsion efficiency by the actions of the turbine installed in the rear side of a ship propeller. In the case of the present invention, the turbine provides an additional rotating force to the rotating axis as the clutch bearing is locked in the rotating direction of the propeller in case the rotating speed of the turbine is faster than that of the propeller; thereby increasing the rotating speed of the rotating axis, or decreases an engine torque. The increase in rotating speed of the rotating axis can be interpreted to a fact that the thrust of the propeller is increasing, thereby increasing the speed of the ship. In addition, when the engine torque decreases, the energy can be saved as the energy consumption becomes smaller. The propeller efficiency is described in the ratio of the energy by an occurrence of thrust to the energy consumed by the rotation; thus when the energy used for the rotation by the turbine is reduced, the propeller efficiency is generally improved. On the other hand, when the rotating speed of the turbine is slower than that of the propeller, the clutch bearing and the turbine does a no-load idling which does not influence the rotating axis at all; thus no energy is lost due to the installation of the present invention. |
