Land-water-air three-purpose rotor aircraft

Abstract

The present invention relates to a land-water-air three-purpose rotor aircraft, which comprises a body, a cabin cover, buoys, wheels, support rods, screw propellers and a motor, wherein the cabin cover is arranged on the body, a cabinet is formed between the cabin cover and the body, the buoys are arranged on both sides of the body, the wheels are arranged below the buoys and can be shrunk into the buoys, four groups of the screw propellers are arranged and are respectively arranged on the front ends and the rear ends of both sides of the body through the four support rods, the motor separately drives the four groups of the screw propellers to rotate, the support rod is a foldable rod, and the screw propellers are positioned at different positions when the support rods are folded. Compared to the aircraft in the prior art, the aircraft of the present invention achieves the applications in the three fields of land, water and air, has the multi-function, has advantages of simple structure arrangement and easy control, and further has advantages of substantially reduced cost, high running stability and high safety compared to other aircrafts.

Description

technical field [0001] The invention relates to an aircraft, in particular to an amphibious, land and air three-purpose rotor aircraft. Background technique [0002] The current aircraft mainly include helicopters, fixed-wing aircraft, rotorcraft, etc. These aircrafts all work in a specific field, such as in the air and in the water, and cannot satisfy the state that they can work under the three conditions of water, land and air. [0003] Chinese patent CN 102774493A discloses a variable-wing type amphibious aircraft, including a fuselage, wings, engines, propellers, and wheels. Deformed wings are installed on both sides of the fuselage, and the deformed wings are composed of more than two wings arranged in parallel. The front end of the wing is fixed, and the rear end of the wing is the movable end. The wings are connected to each other through the connecting rod and the driving joystick. The outer end plate of the deformed wing is equipped with movable flaps. The propell...
