Embodiment 1

[0040] Such as figure 1 , figure 2 Shown, the positive pressure floating type aircraft (hereinafter referred to as aircraft) 10 of embodiment one mainly comprises: airfoil 12; Right fuselage section 30A, left fuselage section 30B and central fuselage section 40; Elevator 50 and a rudder 52 disposed behind the airfoil 12; a propeller type propeller 54 disposed near the rear end of the central fuselage portion 40; and a horizontal stabilizer 56 disposed at the right fuselage portion 30A and the left fuselage portion The rear end portion of 30B connects the right body portion 30A and the left body portion 30B along the body width direction.

[0041] The elevator 50 is mounted on the rear end of the horizontal stabilizer 56 . Such as image 3 As shown, in the section of the airfoil 12 along the front-rear direction of the body and the height direction, it includes: the front end 22 is a circular arc convex forward; and the rear end 26 is a tapered (generally) shape backward (...

Embodiment 2

[0073] Refer below Figure 7 to Figure 10 The positive pressure levitation aircraft 70 according to the second embodiment of the present invention will be described.

[0074]The positive pressure levitation aircraft 70, that is, the full-wing aircraft, is provided with an airfoil 74 with the same height as the right side fuselage part and the left side fuselage part in Embodiment 1 along the entire width of the body. The sum of the width directions of the left and right side walls 73 of the air replenishing portion 72 on which the right guide surface 73A and the left guide surface 73B are formed is equal to the width of the wing portion 74 . The air replenishment portion 72 is formed by the right guide surface 73A, the left guide surface 73B, and the bottom surface 72A.

[0075] At the central position of the airfoil 74, the same central fuselage portion 40 as in the first embodiment is integrally provided. The front end of the central fuselage part 40 is positioned more for...

Abstract

Provided is a positive-pressure floating type airplane (10) comprising an airfoil portion (12), left-right fuselages (30A and 30B), a central fuselage (40), an elevator (50) and a rudder (52) disposed at the back of the airfoil portion (12), a thruster (54) disposed at the back of the central fuselage (40), and a horizontal stabilizer (56) disposed at the rear ends of the left-right fuselages (30A and 30B). The individual front ends of the airfoil portion (12), the left-right fuselages (30A and 30B) and the central fuselage (40) are formed into arcuate shapes in longitudinal sections. On the lower side of the airfoil portion (12), a recessed air capture (32) is formed from the front end to the rear end. As a result, the positive-pressure floating type airplane (10) is floated by the reaction from the air at the time when the air to pass the air capture (32) through the airfoil portion (12) is pushed by the thrust of the thruster (54), and is propelled forward by the component of that thrust.

Description

technical field [0001] The present invention relates to an aircraft, in particular to a positive pressure levitation type aircraft which is pressed and buoyed by the relative air flow (positive pressure) relative to the airframe. Background technique [0002] Ordinary aircraft uses the negative pressure generated on the upper surface of the main wing to lift the body according to the speed difference of the air flow passing through the upper and lower surfaces of the main wing. In this case, separation of airflow tends to occur along the leading edge of the main wing where the angle of attack becomes large, thereby easily causing a stall or an unstable state, and sometimes falling. [0003] Japanese Patent Laid-Open Gazette No. 2004-106784 proposes a gliding kite aircraft that is pressed by air flow (positive pressure) and flies. [0004] The aircraft is called a gliding kite aircraft. When it is at low speed or when it is landing, the angle of attack of the body increases ...
