Description

 The invention relates to aircraft, in particular to airplanes.

 A device for moving in the air is known, consisting of a fuselage with a tail unit in the form of a keel with a rudder and a stabilizer with a elevator, two wings that have straight front and rear edges located one above the other, two chassis are attached to the lower one, each of which is equipped with a float and two wheels, which are placed on the sides of the float body symmetrically with respect to the longitudinal axis (Journal: Wings of the Motherland. 1999, 10, p.19).

 The disadvantage of this device for moving in the air is the inability to move when the engine is not running propeller due to the lack of drive to the wheels of the chassis. A disadvantage also includes the impossibility of movement on a surface limited in width due to the larger wingspan.

 The closest analogue of the invention is a device for moving in the air, including a fuselage with a tail unit in the form of a keel with a rudder and a stabilizer with a elevator, a folding wing with straight front and rear edges, made in the form of the root and rear parts that are articulated between each other equipped with a hydraulic folding mechanism and nacelles in which the wheeled chassis is mounted, and a rear support (Journal: Aviation and Cosmonautics. 1999 12, Fig. Grumman F7G-2N p.25).

 The disadvantage of this device is the inability to self-propel when the propeller engine is idle due to the lack of drive to the chassis wheels. A disadvantage also relates to the impossibility of movement on the surface of the water due to the non-buoyancy of the device structure.

 The technical result achieved by the device according to the invention is the expansion of functionality.

The specified result is achieved in that the device for moving in the air, containing the fuselage with the tail unit in the form of a keel with a rudder and a stabilizer with a rudder, a folding wing, a hydraulic folding mechanism, two chassis with wheels, a rear support, according to the invention, is equipped with a wheel drive the rear support, the front and rear edges of the wing are made in the form of a hyperbolic curve, and the wheel with spring is mounted in the recess of the chassis float, while the drive consists of an engine, two couplings, a gearbox av, gear, driving and driven sprockets and chains, and a float zaglublino wheel niche an amount equal to
B = 2/3 D,
where B is the amount of penetration of the wheel into the niche of the chassis float;
D is the diameter of the chassis wheel,
moreover, the wheel drive of the rear support is located in the cavity of the rear fuselage.

 A device for moving in the air includes a fuselage 1 with a tail in the form of a keel with a rudder and a stabilizer with a elevator. The wing 2 with the leading and trailing edges, made in the form of a hyperbolic curve, consists of the root part “a” attached to the lower surface of the front of the fuselage 1, and two end parts “b”. Four hinges 3 pairwise connect the root "a" and the end "b" of the wing part 2. Two hydraulic cylinders 4 are located on the sides of the fuselage 1, each of which is pivotally connected to the root part "a" by the body, and the rod - to the end part " b. " Two floats 5 are attached to the lower surface of the root part “a” of wing 2. A niche 6 is made in each float 5. Two wheels 7, each with springing, are mounted in a niche 6 and recessed into it by an amount equal to B = 2/3 D, where B is the depth of the wheel; D is the diameter of the wheel. In the cavity of the rear part of the fuselage 1 there is an engine 8, a gearbox 9, a gearbox 10 and two couplings 11 connecting an engine 8, a gearbox 9 and a gearbox 10. The drive sprocket 12 is mounted on the output shaft of the gearbox 10. The chain 13 connects the sprocket 12 to each other with a driven sprocket 14, worn on the axis of the wheel 15 of the rear support.

 A device for moving in the air works as follows.

 On the ground, the fuselage 1 interacts with the surface through two wheels 7 and the rear spore wheel 15, and on water through two floats 5.

 To move in air the end parts "b" of the wing 2 are placed horizontally, Fig.2. In this case, the rod leaves the hydraulic cylinders 4, acts on the end part "b" and reliably holds it in a horizontal position.

 To place the device on the site, limited by the width, the end parts "b" of the wing 2 are translated into a vertical position with a blockage to the longitudinal axis of the fuselage 1, Fig.3. In this case, the rods are pulled into the hydraulic cylinder 4, and the end parts "b" rotate on hinges 3. Due to this, the wing span is reduced. In this position of the wing 2, the device can freely move on the roads.

 For self-propulsion along the road (sealed surface) with the engine running idle, the engine 8 is turned on, for example, an electric motor, from which rotation through the clutch 11, the gearbox 9, another clutch 11 is transmitted to the gearbox 10. From the output shaft of the gearbox 10 from the drive sprocket 12 through chain 13 rotation is transmitted to the driven sprocket 14 of the axis of the wheel 15 of the rear support. Thanks to what provide device self-movement on the road.

 The supply of the device with the wheel drive of the rear support provides movement with the idle engine of the screw.

 Performing the leading and trailing edges of the wing in the form of a hyperbolic curve reduces the wingspan while maintaining the required area corresponding to a given load. Placing a wheel in a niche of a float and ruining it by an amount equal to 2/3 of its diameter reduces resistance when moving in air and moving on water.

 The device according to the invention can be used in airplanes for movement in air, movement on a compacted and water cover.
