An amphibious unmanned aerial vehicle based on ducted vector propulsion

Abstract

The invention discloses an amphibious unmanned aerial vehicle based on ducted vector propulsion, which at least includes an organism system, an aircraft control system, and a propulsion system; the left ducted fan (4 ) and the right ducted fan (3); the aircraft control system has increased the ducted attitude control command coordinated with the left ducted fan (4) and the right ducted fan (3); the installation distance of the ducted fan on the fuselage It is h=30%×H, and H represents the length of the fuselage. By controlling the output direction of the duct vector, the attitude and power of the aircraft are controlled, and the functions of the aircraft sailing into and out of the water and sneaking are realized, thereby improving the operating ability of the amphibious aircraft in complex meteorological and unfamiliar hydrological environments.

Description

technical field [0001] The invention relates to the shape of an amphibious aircraft, more particularly, refers to an amphibious unmanned aircraft based on duct vector propulsion. Background technique [0002] Amphibious unmanned aerial vehicle is a kind of unmanned intelligent mobile platform in the air and underwater. The maneuverability in the air has been relatively mature, and the navigation performance in the water has yet to be mature. Most of the underwater driving devices of the aircraft use propeller propulsion devices. At present, the traditional underwater vehicles propelled by propellers are equipped with a tail rotor and multiple sets of rudder blades. They control the attitude and position of the underwater vehicle by controlling the motor and steering gear to change the propeller speed and the rudder angle of the rudder blade. However, this attitude control method and the traditional underwater aircraft shape increase the self-load of the aircraft, and the re...

AI Technical Summary

Problems solved by technology

[0004] However, the current amphibious aircraft is faced with problems such as vertical take-off and landing for take-off and entry into the water, which is not flexible enough, and has a large power demand, which makes the cost of the engine high. At the same time, the power of the aircraft is mostly propeller or turbojet engine. The direction is not adjustable, and the amphibious performance is not good

Moreover, the structure of the fuselage is fixed, and the same structure is difficult to solve where there are contradictions between the water and air environments.
