Problems solved by technology

Therefore, in the case of a fixed engine power, if you want to fly at high speed, you have to reduce the load, so that both the load and the speed are limited.

Embodiment Construction

[0162] Below in conjunction with accompanying drawing, the present invention will be further described

[0163] Such as figure 1 As shown, it is assumed that the new vehicle is flying horizontally to the right, and the blade 8 rotates clockwise with the main shaft 2 . Then the paddle 8 rotating around the main rotating shaft 2 at the angular velocity ω will hit the air molecules in the unfolded state. When the paddle angle is α, the speed change of the air molecules after the action of the blade surface is in the horizontal direction and the vertical direction. The components are:

[0164] ΔV x =-2V sin α; ΔV y =-2Vcosα.

[0165] (Wherein, V=ωr, r is the distance between the striking position and the main rotating shaft; α is the propeller angle at which the blade is located).

[0166] The component forces of the reaction force of the air molecules on the blade in the horizontal direction and the vertical direction are respectively:

[0167] f x =2 / 3ρhω 2 sinα(R 2 3 ...

Abstract

The invention discloses a vehicle capable of advancing in land, air and / or water, comprising a vehicle body, a main engine or a main motor and a power control and transmission system. The improvement of the invention is that a main rotating shaft extending to two sides of the vehicle body is arranged; a paddle jacket is fixed on the main shaft and provided with a paddle handle capable of rotating around the self center line; paddles are fixed on the paddle handle; the vehicle body and / or the main rotating shaft is provided with a paddle open-close control device for controlling the paddle handle and the paddles to rotate relative to the paddle jacket and the main rotating shaft; the paddle open-close control device is capable of enabling the paddles to generate one-time opening and closing in each period along with the rotation of the main rotating shaft; when the paddle open-close control device is opened, the surfaces of the paddles are positioned on a plane which is parallel or approximately parallel to the main rotating shaft; and when the paddle open-close control device is closed, the surfaces of the paddles are positioned on a plane which is vertical or approximately vertical to the main rotating shaft. The invention acquires a lifting force and a propelling force by controlling the opening and the closing of the rotating paddles in a vertical plane parallel to the vehicle body.

Description

technical field [0001] The present invention relates to a vehicle, in particular to a vehicle that can travel on land, in the air and / or in water. Background technique [0002] There are two main types of aircraft: fixed-wing aircraft and rotary-wing aircraft. Common fixed-wing aircraft are current civil aviation passenger aircraft and large-scale cargo aircraft. Its advantage is that due to the use of fuel combustion and jet propulsion, its power system is relatively strong, and it can reach a greater speed and carry a greater load. But its take-off is by raising the nose after obtaining enough forward speed so that the angle between the fuselage and wings and the horizontal plane changes from zero to a positive value, and then through the interaction between the inclined fuselage and wings and the air molecules function to gain lift for take-off. In order to obtain sufficient forward speed, certain acceleration time and space are required, so fixed-wing aircraft need a ...
