The invention relates to a device for creating aerodynamic lift over static lifting plane and can be used as swimming, flying vehicle in the air for rescue organizations people in extraordinary circumstances, with high-rise buildings, lift / Elevator, crane in areas with dense development, as well as to create additional lifting force during takeoff other vehicles. A device for creating a lifting force, comprising a housing with a chamber and a fan, while the cavity of the chamber are made in the shape of a flattened ellipsoid of rotation and communicated with the external environment through the opening in the housing, located at the bottom of the camera parallel to the plane passing through the greater axis of the ellipsoid of rotation of the hollow chamber, the fan is mounted in the housing bore on an axis of symmetry passing through the minor axis of the ellipsoid of rotation of the hollow chamber, with the possibility of discharge of the fluid inside said cavity (see EN 2232108 C2, publ. 2004). The disadvantage is its low control and low efficiency create a lifting force. The closest to the invention is a device for creating a vertical lifting force with a closed aerodynamic circuit, which can be applied in aviation in Le is athelny apparatus vertical take-off and landing. The device comprises a spherical surface, the bottom of which is formed an annular wing profiles, located on a circle around the source of air flow, which in the radial direction on the annular spherical surface enters the air stream flowing beneath the angle of attack of the ring wing profiles and forming on the upper surface of the vacuum. The lower part of the spherical surface surrounds the annular inlet connected to the recirculation channel to the input of a source of air flow. Canal recirculation air flow after passing them ring profiles and intake received at the input to the source of air flow. The upper part of the spherical surface that is not occupied by the annular wing profiles, has a perforated floor through which this part of the surface is the suction air and a vacuum (EN 93014376, publ. 20.01.1997). However, in this device inefficiently used the upper surface, since the ring profile is only a part of its upper surface. The technical result of the invention is to increase the lifting force due to the increase of the amplitude of the carrier surface with the same cross-sectional diameter of the fan. The result is achieved that the device for creating lift forces which contains the casing, inside the canal recirculation of the working environment, and located in the channel blower for discharge of the working environment, the openings of the intake and output ends of the channel are located opposite each other on the upper surface of the hull of a convex shape with the possibility of her flow of the working medium, characterized in that the channel consists of arranged for suction and before putting it ends straightener parts having a rectangular cross-section and extend into part of the channel located respectively before and after the fan and having a circular cross-section. The intake and output ends of the channel are designed to suction and output the working fluid (air) for multicell channel. The fan accelerates the working environment and ensures its circulation in the channel. The location of the intake and output ends of the channel opposite each other on the upper surface of the housing allows you to organize blowing accelerated in the channel by the flow of the working fluid of the upper surface of the device to create a lifting force. In private versions of the invention the channel is made of a multiple, parallel to each other adjacent sections of the hole sections of the intake and output ends are located along parallel direct the s, each section is connected with the corresponding part of the intake and output ends of the channel, when this part of the channel with a circular cross-section formed by all the above mentioned sections. To ensure the best flow of the upper surface of the body it is made curvilinear with a slight longitudinal curvature. The fan is connected to drive a gas turbine jet engine, the thrust of which is intended to give the device translational motion. The invention is illustrated by drawings, where figure 1 shows an example of the appearance of the device with three-section channel, figure 2 shows the three-section channel is a perspective view, figure 3 is a section a - a in figure 2, figure 4 - cross-section B-B in figure 2, figure 5 - a section b-b In figure 2, figure 6 - section G-g of figure 2. As an example of the claimed device presents ballooning apparatus heavier than air, designed to create aerodynamic lift over static lifting plane, where the air flow shoes bearing surface of the body of the device in the open part of the annular channel. The apparatus consists of a casing 1 within which is made Luggage for passage of the working environment. Luggage made in the form of open profiled three-section channel with suction 2 and prints 3 ends in the form of di is Gusarov. Suction 2 and prints 3 the ends of the channel are located opposite each other on the top of the rectangular surface 4 of the housing, having a small longitudinal curvature. Directly after the inlet 2 and before output 3 the ends of the channel are located straightener parts 5 and 6, having a rectangular cross section (see figure 4). Parts 5 and 6 form a rectifying device and go to part 7 and 8, forming a snail and having a circular cross-section (see Fig.6). Between the parts 7 and 8 is the fan 9, which accelerates the working fluid in the closed circuit channel. The fan 9 is connected to the shaft 10 of the drive jet engine 11, the thrust of which is to create a translational motion. The channel consists of three parallel sections 12, 13 and 14. Each section is connected with the corresponding part 2', 2", 2"' 2 suction end of the canal and with the corresponding part of the 3', 3", 3"' prints 3 end of the channel. A channel with a circular cross-section formed by parts of all three sections of the prevailing rectangular cross-section. Three-section of the profiled channel (channel open loop has a variable cross-section at different intervals of distance, the cross-sectional area depends on the conditions that the gas flow in all sections of the channel value constant in time) allows the annular cross-section near the veins is of istora be converted into a flattened rectangular cross-section over the bearing surface 4. The device operates as follows. The air passes through the intake end of the channel in the form of the diffuser 2 and moves in a rectifying part 5 channel having a rectangular cross-section, then gets to the part 7 of the channel, converts rectangular cross-section in the ring, in front of the fan 9. Fan 9 from the drive motor 11 accelerates the air and provides circulation in the annular parts 7 and 8 of the channel. Then through part 8 of the channel, which converts the circular cross section in a rectangular channel, dispersed air gets first rectifying portion 6, and then in subsonic output end of the channel in the form of the diffuser 3, where else is accelerated. After the diffuser 3 dispersed flow blows curved upper surface 9 of the housing. Due to the significant difference of the velocities of the air flow above and below the device above the static lifting plane occurs a vacuum and, therefore, the lift force. The device hangs in the air due to the speed of the air flow over the bearing plane 4. The braking apparatus is provided by the presence of the apparatus of reverse thrust, and the creation of a reverse reverse. On the device, you may create a translational velocity due to the deviation vector lifting force from the vertical. For driving at low speeds in the apparatus provides a pneumatic who I reactive system on the compressed air from the last stage of the turbine of the gas turbine engine, creates a torque, and a low linear velocity in the horizontal plane. In flight mode the device is controlled: by roll interceptors, which inhibit the flow over the bearing surface, pitch flaps and inclined at an angle of 45 degrees fins with rudders at the rate controlled by rudders. Assumes the operating mode of hovering at a flow rate in the open part of the circuit more than 40-50 meters per second, and when you reach a higher velocity flow in the circuit the device will have a low wing loading, limited by the strength of the wing. The device is able to swim and fly in the air from zero to maximum speed.
