Abstract

FIELD: transport.

SUBSTANCE: invention refers to transport and deals with development of multi-functional transport means intended for being used both as automobile and as aircraft. Automobile includes body, pair of folded wings, propellers, tail fin, underframe with wheels located as per rhomb-shaped scheme, and power plant. Each wing is installed with possibility of being turned by means of a bracket to transverse position above the body so that flight configuration is formed, and to longitudinal position under the body so that road transport configuration is formed. Intermediate pair of wheels is retractable for the wings to come from under the body.

EFFECT: invention allows increasing operating safety of aeromobile in flight and road conditions by means of arrangement of its assemblies.

Description

The invention relates to multifunctional transport equipment intended for use both as a car and as an aircraft.

An aeromobile is known, consisting of a cockpit, a wing, engine nacelles with propellers and an aircraft-type landing gear, while in an aeromobile the wing has an elliptical shape in plan, a profile with sharp leading and trailing edges, composed of segments of the hyperbolic cosine graph, and concavity from below. (Patent RU 2211155, published August 27, 2003)

Also known is a road aircraft with vehicle capabilities, comprising a body, propeller, landing gear and wings, made folding in the transverse direction of the wing. Membrana <http: /www.membrana.ru/articles/technic/2006/02/21/165600.html>.

Both projects of the device provide its movement on roads and flights at a distance of 150-800 km, while its transverse size simplifies the storage problem.

The proposed aircraft, in comparison with the known ones, provides take-off from acceleration, during which the wings are converted from the road-transport configuration into a flight configuration that corresponds to the traditional flight scheme with the upper position of the wings above the center of gravity of the aircraft, ensuring its stability in air.

The problem to which the invention is directed was to ensure that the functions of the aircraft and the car for its safe operation in flight and road conditions are combined with the new layout of the nodes of the aircraft.

The problem is solved as follows.

An aircraft is proposed comprising a body, a pair of folding wings, propellers, a tail, a landing gear and a power unit in which each wing is folded in its longitudinal direction and mounted to rotate in a transverse position above the body, forming a flight configuration, and in a longitudinal position under the body, forming a road transport configuration;

- the chassis wheels are arranged in a diamond-shaped pattern, the intermediate pair of which is made retractable to exit the wings from under the body;

- the folding wing is made of an odd number of longitudinal sections turning around the central section to the position of the aerodynamic profile;

- each wing is mounted on the body by means of a bracket attached to it, mounted to rotate in a vertical body niche in communication with a longitudinal niche to accommodate the wing in the road transport configuration;

- on the roof of the body between the symmetrically located brackets in the center mounted folding double-lever support to maintain the wings in the area of their closure;

- propellers are located symmetrically relative to the longitudinal axis of the body, and their blades are made extendable from the body and folding to the working position;

- The tail unit is mounted on a retractable console.

As shown in the drawings, the aircraft is arranged as follows.

The aircraft contains a body 1, a pair of folding wings 2, propellers 3, landing gear 4, tail unit 5, power unit 6.

The closed body 1 has the most generalized shape for the least aerodynamic drag.

The wing 2 is made folding in its longitudinal direction and consists of an odd number of longitudinal sections 7, deployed around the central section to the position of the aerodynamic profile (figs).

Chassis 4 has four wheels located in a 1: 2: 1 rhombic pattern, in which the front and rear wheels are driving, and an intermediate pair of 8 of which are retractable to ensure the wings exit from under the body.

The wing 2 is mounted to rotate in a transverse position above the body, forming a flight configuration (figure 1), and in a longitudinal position under the body, forming a road transport configuration (Fig.7).

The wing 2 is attached to a bracket 9 bent at an obtuse angle, mounted in a vertical niche 10 of the body, in communication with a longitudinal niche 11 under the body 1, designed to fit the wing in a road transport configuration. To carry out the rotation of the wing, the bracket 9 is mounted with the possibility of sequential rotation relative to the horizontal axis 9a and vertical axis 9b. Between symmetrically arranged brackets 9, a double-lever support 12 is mounted on the roof of the body to support the wings 2 in the area of their closure. When the wing moves from the flight configuration to the road transport configuration, the levers of the support 12 are lowered into the grooves 13. The tail unit 5 is mounted on a telescoping console 14.

The mobile nodes of the aircraft by means known in the art are connected with the power plant 6 and with other drive mechanisms. Automatic drive control. Since these tools are not the subject of the invention, the kinematic scheme in the application is missing.

The use of an aircraft is as follows.

In a static state, the wings 2 are folded in the longitudinal niches 11 of the car. For takeoff, the driver drives onto the road and, accelerating to a speed that ensures reliable control of the aircraft on two leading front and rear wheels, removes the intermediate pair of wheels 8 upwards and, through the longitudinal 11 and vertical 10 niches, unscrews the wings 2 on the brackets 9, unfolds them and raises the supports 12 to the wing-closing zone 2. At the same time, the tail unit 5 is pulled out of the body on the console 14, and the wheelset 8 is returned to its original position to provide sufficient support in take-off mode. Pulling force create propellers 3, extendable from the body with the disclosure of the blades to the working position. The location of the wings above the center of gravity of the aircraft ensures its stability in the air. When landing, all nodes of the aircraft sequentially return to their original position for the implementation of the road transport mode of movement (Fig.7).

Thus, the claimed layout of the aircraft ensures the combination of the functions of the aircraft and the car when it is used.
