PROBLEM TO BE SOLVED: To provide a wave-making resistance reduction ship capable of reducing a bow wave that is a main cause of wave making resistance without changing a ship type by paying attention to ship body surface pressure, and to provide a designing method of the wave-making resistance reduction.SOLUTION: The wave-making resistance reduction ship 10 includes: a water inlet 20 provided to take in water in a high dynamic pressure generation part A generated at a bow tip 11 during the voyage of the ship 10; an outlet 30 provided to discharge the water in a low static pressure part Bnearest from the bow tip 11 among a plurality of low static pressure parts generated on the ship body side face of the ship 10; and a connection pipe part 40 provided to interconnect the inlet 20 and the outlet 30 in the ship body. The water of the high dynamic pressure generation part A is guided to the low static pressure part Bvia the connection pipe path 40 to reduce wave making resistance.SELECTED DRAWING: Figure 1
【課題】船体表面圧力に着目して、船型を変えることなく、造波抵抗の主要因である船首波を低減する造波抵抗低減船舶及び造波抵抗低減船舶の設計方法を提供すること。【解決手段】船舶10の航行時に船首先端部11に発生する高い動圧発生部Aに設けた水を取り込む取水口20と、船舶10の船体側面に発生する複数箇所の低い静圧部のうち船首先端部11から最も近い低い静圧部B1に設けた取り込んだ水を吐水する吐水口30と、取水口20と吐水口30を連絡する船体の内部に設けた連絡管路40を備え、高い動圧発生部Aの水を、連絡管路40を介して低い静圧部B1に導いて造波抵抗を低減した。【選択図】 図1
