Abstract

FIELD: aviation.

SUBSTANCE: air balloon shell on the wall of which on the outside there are light sources, and in the wall on the bottom there is an opening for entering the air heated by a burner. The light sources are arranged linearly along an arc of a circle. The opening for entering the air heated by the burner has a shutoff valve. The light sources in the form of tapes with LEDs are connected to each other in series/in parallel by conductors of electric current. The valve is made in the form of a gate located under the shell. The valve is made in the form of a flap located in the cavity of the shell.

EFFECT: increased safety of the air balloon flight.

Description

The invention relates to the field of modeling aeronautical apparatus.

Known shell of the balloon, in the wall of which a hole is made below for the entry of heated air by the burner [1]. Outside, a light source can be installed on the wall of the shell.

The objective of the invention is to increase the flight safety of the balloon, saving warm air.

The technical result of solving the problem is achieved by the fact that in the shell of the balloon, on the wall of which light sources are installed on the outside, and in the bottom wall there is a hole for the entrance of heated air by the burner, the light sources are linearly in an arc of a circle, and the hole for the entrance of heated air of the burner has the valve blocking it. Light sources in the form of strips with LEDs are interconnected in series / parallel with electric current conductors. The valve is made in the form of a valve located under the shell. The valve is made in the form of a sash located in the cavity of the shell.

In FIG. 1 and 2 respectively show the shell of a balloon with light sources in the form of strips with LEDs mounted on vertically and horizontally arranged circular arcs; in FIG. 3 and 4 are views respectively in FIG. 1 above and below; in FIG. 5 is a view of FIG. 2 bottom; in FIG. 6 and 7, respectively, are shown diagrams of closing the openings for the inlet of the air heated by the burner with valves in the form of a valve and a sash.

The shell of the balloon (Fig. 1-5) has the shape of a sphere with a rigid wall 1, covering the cavity 2. In the bottom wall there is a round (square or other shape) hole 3 for entering the air heated by the burner 4. Outside, light sources 5 in the form of tapes 6 with LEDs are mounted linearly along an arc of a circle on the wall. Tapes with LEDs are interconnected in series and / or in parallel with conductors 7 of an electric current with a source (not shown) of electric current. Performed in the wall from below into the hole for the inlet of the air heated by the burner has a valve 8 shutting it off, operating from an electric, pneumatic actuator (not shown). The valve is made in the form of a valve 9 (Fig. 6) located under the shell. The valve can be made in the form of a rotary flap 10 located in the cavity of the shell (Fig. 7).

Making a model of a prototype shell of a balloon.

1. From a light rigid thin-walled material (plastic, alloys based on aluminum, titanium, magnesium), a balloon shell is made that looks like a sphere (Fig. 1-5). In the wall 1 of the shell covering the cavity 2, a round or other shape, for example a square, is made from below for opening 3 of the air heated by the burner 4.

2. They make (acquire) light sources 5 in the form of ribbons 6 with LEDs emitting white and red light. The tapes are attached externally to the shell wall linearly along an arc of a circle, placing them vertically (Figs. 1-3) and / or horizontally (Figs. 4 and 5). The tapes are connected in series / parallel by conductors 7 of an electric current to a current source, for example, a battery (not shown).

3. Depending on the shape of the hole at the bottom of the shell, an overlay valve 8 is made having an electric or pneumatic actuator (not shown). The valve may have a valve 9 located under the shell (Fig. 6), or a rotary shutter 10 located in the cavity of the shell (Fig. 7). The valve and sash are made of heat-insulating material. It is possible to produce a shut-off valve with several valves or flaps, for example with six flaps for a hexagonal hole.

The finished shell is filled with warm air, as a result of which the balloon goes into ballooning mode. With a regular flight of a balloon with such a shell, white light sources are turned on in the dark. In case of an emergency, for example, a threat of collision with another flying device, they turn on red sources, change the height of the balloon. This improves flight safety. In the presence of a shut-off valve at the opening for the entry of heated air from the burner into the cavity of the shell, the loss of warm air is reduced. Valves, valve flaps open and close, respectively, with the burner working and not working. This saves fuel.

The invention improves the safety of flights of the balloon, saves warm air located in the cavity of the shell.
