Flight vehicle generating a lift from an interior thereof

Abstract

The invention discloses a flight vehicle generating a lift from an interior thereof. The fluid channel inside the flight vehicle communicates with the engine and the ports on the upper surface of the outer shell. With the powerful suction of the engine, the fluid on the upper surface of the outer shell is quickly sucked into the fluid channel via respective ports under conditions of long path, large area, high speed and low air pressure, which results in large lift from the interior of the flight vehicle. In the course of generating the lift, the fluid resistances of the fluid wall and the fluid hole are sucked into the fluid channel through the ports at the front and the surrounding area of the flight vehicle, then high-speed fluid is emitted from the rear port. This approach contributes greatly to the transformation of the existing flight vehicle. The present invention significantly improves the lift, the speed and the carrying capacity of the existing flight vehicle with lowered energy consumption.

What is claimed is: 
     
         1 . A flight vehicle generating a lift from an interior thereof, wherein the flight vehicle comprises a engine and a fuselage shell without wing; a plurality of ports are arranged on surface of the fuselage shell, a plurality of exits are arranged at a tail of the rear of the fuselage, the ports and the exits are communicated with each other through a fluid channel; the engine is located inside the fluid channel and have an air-in vent and an air-out vent, wherein the air-in vent connects with the port, and the air-out vent communicates with the outside by connecting the exit;
 the engine drives the fluid to flow within the fluid channel of the fuselage shell, so that the fluid speed formed inside the fluid channel and over an upper surface of the fuselage shell communicating with the fluid channel is larger than that on lower surface of the fuselage shell in a natural state, resulting in a pressure difference between the upper and lower surfaces of the fuselage shell of the flight vehicle and thus creating lift.   
     
     
         2 . The flight vehicle generating a lift from an interior thereof according to  claim 1 , wherein each port on the surface of the fuselage shell communicates with the fluid channel, wherein the port on the upper surface is the first port, the port on both sides or around is the second port, the port on the bottom lower surface is the third port, the port at the front in the movement direction is the fifth port, at least one of the ports is provided with a controller and an electrically controllable door connected to said controller, and the controller controls the opening and closing of the electrically controllable door and the altering of the air-guiding angle so as to control the amount of the charged air at different parts of the fuselage shell to produce a pressure difference and further control the flight direction or lift of the flight vehicle when flying. 
     
     
         3 . The flight vehicle generating a lift from an interior thereof according to  claim 2 , wherein the controller causes the flight vehicle to generate or eliminate the lift by controlling the opening and closing of the ports. 
     
     
         4 . The flight vehicle generating a lift from an interior thereof according to  claim 3 , wherein the engine draws fluid through the first and second ports into the fluid channel, resulting in a huge pressure difference between the upper half and the bottom of the flight vehicle to create a great lift, and thus the flight vehicle can travel in the air. 
     
     
         5 . The flight vehicle generating a lift from an interior thereof according to  claim 3 , further comprising a plurality of spoiler panels located at the bottom of the fight vehicle and arranged in a manner that a convex surface of one spoiler panel faces a concave surface of its neighboring spoiler panel; and the spoiler panels communicate with the fluid channel through the third port located at the bottom of the flight vehicle, so that the speed of the fluid passing through the inside and outside of the fluid channel of the bottom of the flight vehicle is larger than that over the upper part of the flight vehicle, resulting in the lift resistance of the flight vehicle eliminated and the grip increased. 
     
     
         6 . The flight vehicle generating a lift from an interior thereof according to  claim 1 , wherein the fuselage shell comprises an outer shell and a closed inner shell, the fluid channel is located between the outer shell and the closed inner shell. 
     
     
         7 . The flight vehicle generating a lift from an interior thereof according to  claim 6 , wherein the inner shell or the outer shell of the flight vehicle is provided with an inflatable layer. 
     
     
         8 . The flight vehicle generating a lift from an interior thereof according to  claim 7 , wherein the inflatable layer has a plurality of springs distributed around, between the outer shell and the inner shell is also distributed a plurality of springs around.
