Description

The invention relates to aviation, in particular to aeronautics, and in particular to a device for tethered balloons and to devices for advertising carried out using an aircraft, in particular a balloon

Currently, the production of advertising balloons and airships is associated with the problem of their one-time use, in which the device made for one company after the end of the advertising campaign is decommissioned and sold at a reduced price due to the impossibility of repainting to the requirements of the new company.

When hanging a variety of billboards under the apparatus, the coupling windage increases, which in some cases is unacceptable.

Many manufacturers of technical means of advertising see a way out of this in the use of the surface of a balloon of an aerostatic aircraft (ALA) as a screen for projecting onto it an image of the currently set advertising campaign or showing films.

The design of such an ALA in a complete set may include:

- a projector of a projection complex with a screen;

- a complex for receiving and transmitting a TV signal;

- a complex of controlled cameras;

- programmable image player;

- Cellular Repeaters;

- elements of attachment to the ground, if it is a tethered balloon;

- propeller systems, if it is an airship;

- elements of radio control, if it is an unmanned ALA.

In addition, the apparatus can be equipped with controlled speakers, instruments for measuring atmospheric parameters, and other equipment, the operation of which as intended requires lifting to a height.

ALA, made in accordance with the full scheme, can be used at major sporting events. Less equipped are suitable for the entire spectrum of the advertising market.

The use of special airships with a projector for the above purposes is the most costly area and less effective for zonal use, as All equipment and systems necessary for controlled flight, take-off and landing are placed directly on board.

The least expensive, simple and reliable direction is the use of specially designed tethered balloons with a projector.

Tether balloons include a soft-structured body, a cable tie assembly, rigging, and tail assembly. A significant part of aerostatic lifting force is used by tethered balloons to lift the weight of a tethered cable that grows with increasing height. A tethered cable fixed at one end to the aerostat's harness assembly and the other to the ground winch drum is an important force element that holds the aerostat at a given parking height for the estimated time. It also allows you to lower the balloon to the ground for transportation, maintenance of equipment and replenishment of onboard reserves of lifting gas.

Known tethered balloon device useful model K.S. Bykova (patent RU No. 566699, 04/05/2006), which contains a gas-tight shell in the form of an inverted truncated pyramid, held at working height by four tethered cables. A halogen lamp is used as a light source, the rays of which are projected onto the inside of the shell from the inside, and the advertising medium is made integrally with the shell and placed on its outer side surfaces as separate parts or in the form of advertising extensions. Here, the mass of four tethered cables is excessive, requiring increased costs of lifting gas. To replace advertising information, it is necessary to lower the balloon to the ground.

A known method of forming an image of advertising, including projecting an image obtained using a laser projector and control system into the airspace and using the surface of an aerostat in the air as a screen (JP patent No. 4-166982, G09F 9/00, 1992 ) This method provides a complex device with the possibility of forming an advertising image in airspace directly from the surface of the earth. A serious drawback of this method and, accordingly, the device is the difficulty of synchronizing the projector's rays with the position of the aerostat, which varies randomly under the influence of wind flows, as well as a decrease in the quality of the resulting images. Obtaining high-quality images is associated with great technical difficulties and an increase in the cost of advertising services.

A tethered balloon is known for designing a utility model MB Shakabaev with a group of co-authors (KZ U patent No. 1059, 04/15/2012), which contains a tethered balloon and an advertising medium made of a polymer film, mounted on the surface of the shell with the possibility of illuminating it by airborne means. In this device, it is impossible to replace the advertising field without launching a balloon and it is impossible to demonstrate moving images and clips. In addition, the linear tensile coefficients of the shell and the film are incompatible, which under certain conditions will lead to its rupture or separation from the surface.

Known tethered balloon device V.G. Vohmyanina (patent RU C1 No. 2002314, G09F 21/00), which contains an advertising board connected to the control unit, located on the outer surface of the tethered balloon-shaped disk facing the Earth. According to the technical nature of this scheme is selected as the closest prototype.

The main disadvantages of the prototype are:

- great complexity of manufacturing, because mechanically and electrically complex technical device in the form of a board is used;

- the complexity of operation and transportation, since the scoreboard is a rigid product of large overall dimensions, which is mounted and dismantled in sections;

- a large number of electrical connections that reduce reliability;

- the inability to obtain high-quality images on the screen;

- high risks of failure of the scoreboard due to atmospheric factors: humidity, temperature, wind gusts, rain, snow, icing;

- a large mass of displays requiring large volumes of lifting gas;

- difficulties in balancing and stabilizing the aerostat at a parking height due to the weight of the scoreboard distributed over the area.

The objective of the invention is to search for a technical solution that allows you to receive promotional video images, video clips, films on a large flying screen in stable playback conditions due to the special device of the tethered balloon complex, as well as eliminating the listed disadvantages of the prototype.

The objective of the invention is solved in that it is proposed to use a ground-controlled projector (video projector, laser projector, film projector, slide projector) rationally arranged in the housing of the cable-to-balloon tethered cable assembly to form an image on the screen of the bottom surface of the tethered balloon shell.

The technical result obtained is characterized by the following essential features:

- a projector is fixed in the housing installed in the cable tie assembly, and the lower surface of the aerostat, which is the screen, is made in a shape as close as possible to the plane;

- the length of the slings of the balloon is consistent with the required distance from the projector lens to the screen;

- the balloon body in the plan may have a round shape, a rectangular shape with rounded corners, or an intermediate shape between a round and a rectangular one;

- the cable is provided with the ability to supply electrical power to power the projector;

- the projector is provided with the possibility of receiving a video signal via a cable cable or via a digital radio channel;

- additional equipment is placed in the projector case or in a container fixed outside the screen area, the effective operation of which requires a rise to a height.

In FIG. 1 shows a layout of a tethered balloon.

The tethered balloon device with the projector of FIG. 1 includes:

balloon body (1) with vertical (2) and side (3) stabilizers in the tail. Slings (5) of the aerostat distributed around the perimeter of the outer contour of the hull (1). The screen (5), which is simultaneously the lower part of the balloon shell. Raster (6) of the projected information beam of light. Projector housing (7). Projector (8). The mount (9) of the tethered cable to the balloon. Tether cable (10). Winch (11). The container for laying the balloon. Mobile vehicle (13) based on a car chassis. W is the speed of the air flow on the balloon.

A tethered balloon device with a projector operates as follows (see Fig. 1):

In the area of the upcoming demonstration of advertising information or video clips, together with a lifting gas gas tank, the vehicle delivers a stationary tethered balloon module with a projector or it is delivered together with a specialized car (13). During the deployment process, the shell (1) of the aerostat, together with the plumage (2) and (3), is removed from the transport container (12) and filled with lifting gas (most often safe helium, in exceptional cases, with hydrogen). It takes off from the ground and the tension of the slings (4) from the level of the leash node (9) and the body (7) of the projector (8). After checking the connections, the operator enters the control mode of the winch (11) and hand over the winch cable-rope (10), ensuring that the balloon rises to its working height (for example, 300-500 m). The tethered balloon is designed so that its position at the working height is stable. Therefore, when changing the wind speed pressure, the trim angle of the balanced aerostat changes slightly within 5-10 degrees and the angular position of the screen in space remains almost constant. Within certain limits, the drift and the parking height of the aerostat are changed, which can be adjusted during winch control (11).

The operator, making sure that the balloon is at a working height and is stable in the direction of the wind W, turns on the power supply to the projector via cable (8) and monitors the occurrence of a light beam raster (6) and the appearance of the image on the screen (5) specified by the programmable image player or video clips.

At the same time, additional equipment is being operated at the aerostat complex, elevated to a height with other tasks (repeaters, video cameras, etc.)

The complex is able to operate continuously around the clock for at least two weeks until the moment when it is necessary to replenish the supply of lifting gas.

After completion of the complex in the area of demonstration of advertising information, the projector (8) is turned off. The balloon is pulled by a cable (10) to the ground with a winch (11). The lifting gas from the shell (1) is pumped out. The balloon is placed in a container (12) and a specialized car (13) leaves for the new destination.

Using a specialized car (13) transfers the entire complex to the category of mobile and quick-deploy.

Using a tethered balloon with a projector provides several advantages. These include:

1. Stable distance between the projector lens and the screen due to the constant tension of the balloon lines.

2. A stable angular position of the screen relative to the projector lens, independent of the strength and direction of the wind.

3. Images projected onto the lower surface of the balloon shell are in the shade and are not attenuated by direct sunlight, preserving the original quality.

4. Advertising programs can change "on the fly", and dozens of manufacturers can be sequentially advertised on a single balloon complex, as well as on a television screen.

5. On the screen of the aerostat complex, a close-up of performances of artists at stadiums, where there is a huge number of spectators who are at great distances from the stage, can be broadcast.

The disadvantages of the aerostat complex include:

1. The need to use large volumes of relatively expensive gas - helium. Cheap pure hydrogen is still explosive. Safe phlegmatized hydrogen is not yet provided with conditions for widespread use.

2. Certain inconvenience is caused by the need to use gas holders for transporting the required amount of lifting gas and pouring it into a deployable tethered balloon.

The proposed device tethered balloon with a projector allowed:

- solve the main problem of the invention;

- simplify operation and transportation;

- eliminate a large number of electrical connections and increase reliability;

- provide conditions for obtaining high-quality images on the screen;

- reduce the risk of failure due to atmospheric factors;

- by saving the mass of the structure to reduce the required volume of lifting gas;

- to provide the technical feasibility of effective balancing of the balloon on the load of the wind speed head.
