JPH0357791A COLLISION PREVENTING DEVICE OF HYDROFOIL CRAFT FOR DOLPHIN AND WHALE 失效

摘要： PURPOSE:To prevent the collision of the hydrofoil craft with dolphins and whales by installing a supersonic wave transmission means which transmits the supersonic wave having the directivity of the cycle which forms the specific sound pressure which dolphins and whales evade in the sea in the front in a specific forward distance toward the sea forward in the advance direction, in the lower part of a front part start or onto a front wing. CONSTITUTION:A supersonic wave transmission means is installed in the lower part of a front start 12 of a hydrofoil craft JF or onto a front wing 13, and the supersonic wave having the directivity of the cycle in 100kHz or less having the sound pressure of 120 - 130dB which dolphins and whales evade is transmitted in the sea in the front by about 100 - 120m forward in the advance direction. Therefore, when dolphins and whales catch the supersonic wave in the front by about 100 - 120m, it takes about 4 - 5 seconds for the approach of the hydrofoil craft, and dolphins and whales get away to the side separating from the advance direction so as to separate from the supersonic wave and the collision of the hydrofoil craft with dolphins and whales can be surely prevented.

摘要： PURPOSE:To enhance stability and quietness of the titled craft by providing hydrofoil supporting legs having been arranged at the front and rear of the hull, and hydrofoils having been fitted to the lower ends of the hydrofoil supporting legs, and by making the cross-sectional shape of each hydrofoil supporting leg a nearly triangular shape. CONSTITUTION:At the lower ends of hydrofoil supporting legs 2, 3, hydrofoils 4, 5 extending horizontally in the right and left directions respectively are provided. To the upper end of the front supporting leg 2, a steering shaft 7 is connected, and in the interior of the rear supporting leg 3, a duct 12 is provided so as to penetrate it vertically, and further on the lower end side surface of the duct 12, a water intake port 16 is provided, and on the upper end part, a jet pump 14 is provided, and it is so contrived that the jet pump is driven by an engine 13 to jet water flow from a jet nozzle 15, thereby a propulsion force can be produced. The cross-section of each of the front and rear supporting legs 2, 3 is formed nearly in a triangular shape. Thus, when a hull 1 glides and water is brought into contact with the vertexes of the triangles of supporting legs 2, 3, water is smoothly separated, and the rise of water along both side surfaces of the supporting legs 2, 3 can be restrained to a lower level, and further the separated water ridges flow rearward as they are, without meeting and colliding each other at the bases of the triangles.
