Problems solved by technology

However, the hydrofoil of the hydrofoil speedboat is still submerged in the water and is also subject to water frictional resistance, so the speed of the hydrofoil speedboat cannot be greatly increased.

Embodiment Construction

[0035] The present invention will be further described below with reference to the drawings and embodiments.

[0036] Such as figure 1 As shown, the specific implementation of the present invention includes a main hull and two auxiliary hulls on both sides. The front end of the main hull is provided with a double bulbous bow 2, and the bottom of the main hull is provided with a recyclable adjustable hydrofoil and a fixed immersed hydrofoil. All are equipped with a cavitation device, and a ducted fan-type propeller is provided at the rear of the fixed immersed hydrofoil at the tail, and the auxiliary hull is only equipped with a fixed immersed hydrofoil.

[0037] Such as figure 2 As shown, the front and rear of the bottom of the main hull are respectively provided with a recyclable regulating hydrofoil 4 and a fixed immersed hydrofoil 7. The recyclable regulating hydrofoil 4 and the fixed immersed hydrofoil 7 are respectively used as the bow and stern hydrofoil of the main hull. Th...

Abstract

The invention discloses a supercavity-hydrofoil triple-hulled vessel. Double bulbous bows are arranged at the front end of a main hull; a retractable adjusting hydrofoil and a fixed submersible hydrofoil are arranged at the bottom of the main hull; a cavitation device is arranged on each of the retractable adjusting hydrofoil and the fixed submersible hydrofoil; a ducted fan-type propeller is further arranged at the back part of the fixed submersible hydrofoil on the tail part; fixed submersible hydrofoils are arranged at the tail parts of the auxiliary hulls. A medium on the surfaces of the hulls is changed from water into a mixture of water and vapor, so that the sailing speed of the ship is increased, the hulls can be lifted to reduce friction between water and the hulls, longitudinal shaking, vertical vibration and other adverse effects of the hulls to relatively large extent are avoided, and the resistance reducing efficiency of the hydrofoils is greatly improved; the ducted fan-type propeller improves the propulsive efficiency, and the service life of the propeller is significantly prolonged.

Description

Technical field [0001] The invention relates to the field of new-type high-performance ship manufacturing, in particular to a supercavitating hydrofoil trimaran. Background technique [0002] The 21st century is the century of the oceans. This has become an indisputable fact. Strengthening the control of the near and far seas, and safeguarding the interests of the oceans have gradually become the strategic needs and competitive goals of all maritime powers. Ocean development, maritime transportation, and mobile response are all related to each other. Ship speed is closely related, and countries generally believe that the focus of military and civilian ship development in this century is high speed. [0003] The wave-making resistance of the trimaran at high speed is much lower than that of other ship types, and the additional hydrofoil can make the trimaran produce upward lift effect to achieve the purpose of speed increase and drag reduction, and make the trimaran faster The perf...
