Problems solved by technology

[0003] At present, most aircraft are generally controlled by multiple propellers to complete the forward, backward, floating, and submerging actions of the aircraft, but the flexibility is not enough to complete difficult actions, and because the propulsion system accounts for a large proportion, it increases navigation The shape and size of the device
There are also some aircraft that use fin rudders to control single propeller propulsion, which has a large turning radius and poor flexibility
A few bionic propulsion using steering gear swing has poor maneuverability and load-bearing performance compared to propeller propulsion

Embodiment Construction

[0025] This embodiment is a chain type double-section vector propulsion underwater vehicle; it has three propellers and two steering gears. The gravity of the aircraft itself is slightly smaller than its buoyancy, and about 1 / 6 of the volume should be on the water surface in the static posture in the water. Among them, the forward and reverse rotation of the propellers on both sides can make the aircraft float or dive, and the differential speed of the two propellers The aircraft can be tilted, and the rolling action can be realized if the differential speed continues to increase. The main propeller at the tail is the main driving force for the forward movement of the aircraft, and its positive and negative rotation provides the forward or backward power for the aircraft. Each compartment is sealed and connected to each other by threaded sealing bolt wiring. Through the cooperation of three propellers and two steering gears, various underwater actions are completed.

Abstract

The invention discloses a chained double-section vector propulsion underwater vehicle. The chained double-section vector propulsion underwater vehicle is composed of a main bin, a battery bin, a firstpropeller, a second propeller, a front steering engine, a rear steering engine and a main propeller. The first propeller and the second propeller are arranged in a mirror image mode relative to the main bin, the rotating directions of propeller screws of the propellers are opposite, the upward floating speed and the downward diving speed of the aircraft body can be changed by adjusting the rotating speed of the motor, and the transverse rolling posture of the aircraft is adjusted by changing the rotating direction. The front steering engine and the rear steering engine are located between themain bin and the battery bin and connected in series through a double-U-shaped sheet metal part. The gravity center of the aircraft main body and the relative position change of the buoyancy center are changed by adjusting rudder angles of the two trunk steering engines, so that the aircraft attitude is controlled and the propelling direction of the main propeller is adjusted. All the cabins aresealed and are connected with one another through threading sealing bolt wiring. Various underwater actions are achieved through mutual cooperation of the propeller and the steering engine, and high flexibility and practicability are achieved.

Description

technical field [0001] The invention relates to the technical field of underwater vehicles, in particular to a structure of a chained double-section vector propulsion underwater vehicle. Background technique [0002] The development of unmanned underwater vehicles first began in the late 1950s, when they were mainly used for marine scientific research. In recent years, the autonomous control level and propulsion power of unmanned underwater vehicles have been further improved and developed, and have the advantages of low cost, no casualties, suitable for large-scale production, and can perform tasks in various environments and even high-risk sea areas. It can carry various types of sensors or weapons, perform detection and strike tasks, and has great advantages in military operations and energy development. In recent years, underwater vehicles have gradually been used in the civilian field, and the market demand is optimistic. [0003] At present, most aircraft are general...
