Water-surface monomer unmanned wing planing boat with two hydraulic propellers

Abstract

The invention discloses a water-surface monomer nobody wing planing boat with two hydraulic propellers. The relatively front boat body bilge, of a boat midship of a main boat body is provided with two flared wing type columnar compound hydrofoils which are composed of two section-variable columnar attachment bodies and two wings; the tops of the two section-variable columnar attachment bodies are in seamless connection with a boat body; the bottom of one section-variable columnar attachment body is fixedly provided with one wing; the included angles between the two wings and a horizontal plane are 25-45 degrees; the relatively front part of each wing is provided with a water inlet communicated with a water outlet. An original hydro skimmer with a hydraulic propeller is lowered to a bottom wing from the water inlet on a sliding surface, so that a forward thrust can be provided so as to enable the boat to advance, a vertically upward added lift force also can be provided so as to enable the front part of the boat body to be lift up, and further the boat can slide better; the water inlet has a distance with the sliding surface, so that the resistance can be well reduced, the sliding efficiency and the rapidity of the boat are greatly improved.

Description

technical field [0001] The invention relates to a ship, in particular to a water surface single unmanned wing skid boat with double water jet propellers which is used for dynamic monitoring of various operations on the water surface. Background technique [0002] At present, surface unmanned boats generally adopt a single-body type. Due to the small displacement and size of the boat type, it is particularly sensitive to the external wind, waves, and current environment, and has a large range of swaying motion in wind and waves. In order to maintain a relatively stable speed, for displacement boats, water jet propellers are generally installed at the bottom of the hull. Due to the small tonnage of the surface single-body unmanned boat, it is generally in a semi-planing or fully gliding state when sailing. In this way, the sliding surface is destroyed, the resistance is increased, and the gliding efficiency and rapidity of the boat are greatly reduced. Contents of the inven...
