Compared to those with propulsion devices,
By suppressing the reaction torque through bidirectional rotational transmission, the rotational force around the hull can be suppressed as much as possible, and depending on the settings, the ship can be propelled with zero reaction torque. Therefore, it is possible to recover the kinetic energy by increasing the diameter of the propeller at low rotation speeds and by rotating the trailing stream of the propeller, which improves propulsion efficiency, and because there is no need to take reaction torque into account, it is possible to achieve large horsepower. can do. Furthermore, since a propeller with a large diameter and low rotation speed can be used, cavitation and noise generation can be suppressed even when submerged in relatively shallow water.
