Embodiment Construction

[0013] see figure 1 As shown, the present invention is a water surface single-body unmanned boat with a water jet propeller, including a main hull 1 and a superstructure 2, and the superstructure 2 is above the main hull 1. The designed waterline length of the main hull 1 is L, BL is the baseline, and the distance from the superstructure 2 to the bow is 1 / 4L-2 / 5L. The water outlet 36 of the water jet propeller is on the main hull 1 at the stern. There is a composite stabilizing fin 3 at the bottom of the stern of the main hull 1 .

[0014] see figure 1 and figure 2 As shown, the composite stabilizing fins 3 are located directly below the stern of the main hull 1, and the composite stabilizing fins 3 are located on both sides of the stern, symmetrical along the width direction, and vertically arranged at the bilges on both sides. The composite stabilizing fin 3 is composed of two cylindrical appendages 31, 32 and a wing 33 fixedly connected to the bottom surfaces of the tw...

Abstract

The invention discloses a water surface single-body unmanned boat with two water-jet propellers. A combined stabilizing fin is arranged at the bottom of an after-body of a main boat body and is composed of two cylindrical attached bodies and a wing, wherein the two cylindrical attached bodies are symmetrical in the width direction, the wing is fixedly connected with the bottom surfaces of the two cylindrical attached bodies and symmetrically arranged in the width direction, the wing is perpendicular to the two cylindrical attached bodies, the tops of the two cylindrical attached bodies are connected with the main boat body in a seamless mode, the wing is provided with two water inlets, and the water inlets are communicated with a water outlet to from a main flow passage for water flow. The water-jet propellers are arranged at the bottom end of the boat body and leans to the back, the noise of the boat body is lowered, the sliding surface of the unmanned boat is not damaged, and transverse stability and longitudinal stability are obviously improved.

Description

technical field [0001] The invention relates to a ship, in particular to a water surface single-body unmanned 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 unmanned boat, it is generally in a semi-planing or fully gliding state when sailing. At this time, simply install a water jet propeller directly on the original semi-planing or gliding hull itself, and the water inlet is on the gliding surface. On the surface, the sl...
