Document Type and Number:
Japanese Patent JPH1159562
Kind Code:
A
Abstract:
PROBLEM TO BE SOLVED: To prevent the reduction of the structural strength of a hull by forming injection ports in a duct and flowing air into the duct by a compressor device provided in the hull from the injecting ports to jet the air. SOLUTION: A duct 11 is provided in such a manner that it surrounds the surface of an outer plate of a hull, a plurality of injection ports 12 are formed backward in the duct 11, and a multiporous plate 13 is attached to the injection port 12 to block an opening of the injection port 12 in a small high speed vessel 10. A compressor device 14 which is a compressing means is provided inside the hull, this compressor device 14 is constituted by an air suction port 14a and a compressor 14, the air suctioned through the air suction port 14a is compressed by a compressor 14b to feed into the duct 11, and the compressed air supplied into the duct 11 jet from the injection 12 through the multiporous plate 13.
