Abstract

PURPOSE:To improve the navigation performance of a hull and the propulsion efficiency by installing a torpedo-shaped submersible body onto the underside of the bottom in the front part of the hull and installing a screw propeller at the rear edge. CONSTITUTION:A torpedo-shaped submersible body 2 is installed onto the underside of the bottom in the front part of a hull 1. A screw propeller 4 driven by an engine is installed at the rear edge of the submersible body 2. Therefore, the movement of the hull in waves can be suppressed by keeping the submersible body 2 under water-level during high-speed navigation, and the navigation performance can be improved, and the following-wake energy can be recovered by the operation of the screw propeller 4 in the following wake due to the submersible body 2, and a portion of the resistance increase due to the installation of the submersible body 2 is offset, and the propulsion performance can be improved.

とする。The present invention attempts to solve these problems, and by recovering the energy of the wake of the submerged body, it is possible to offset the increase in resistance and improve the propulsion performance. The purpose of the present invention is to provide a high-speed boat with a submersible body.

回収が行なわれる。In the above-described high-speed boat with a submerged body of the present invention, the torpedo-shaped submerged body provided under the bottom of the front part of the hull reduces hull movement in waves, and the screw propeller operates in the wake of the submerged body. By doing so, the wake energy is recovered.

This recovers the wake energy, so part of the increase in resistance due to the installation of the submerged body 2 is canceled out.
This will improve propulsion performance.
