Kytoon

FIELD: aircraft engineering.

SUBSTANCE: invention relates to lighter-than-air airships. Proposed kytoon comprises balloon, anchor rope, ground support equipment and pay load. Anchor rope represents rope-hose with one or several gas spaces to feed gas to fill balloon and that for electric generator that supplies onboard equipment, payload and motors. The latter are used to oppose wind force and hold kytoon at preset operating point.

EFFECT: increased time of continuous operation at larger altitudes.

 

The invention relates to the field of radio communications using flight-lifting equipment for the expansion of coverage of radio communications, broadcasting, monitoring, control, and intelligence.

A known method of extending the zone of reception of radio equipment due to the rise of antennas to a greater height. Known technical means of lifting antennas to greater heights:

space vehicles and satellites;

- airplanes, helicopters, airships, free and tethered balloons;

- radio tower and antenna mast device.

Closest to the present invention are tethered balloons.

Known tethered balloon complexes, comprising: a balloon, cable, ground maintenance and payload.

The balloon consists of an aerodynamic shell shape with automatic maintenance of the pressure in all filled with helium and air cavities, rigging, navigation equipment, the emergency power supply and lightning protection.

The cable holds the balloon, providing a supply of onboard systems and payload, as well as the diversion of lightning and static electricity.

The range of ground handling includes a balloon holding device is equipped with a winch, tools, timing, system energosnabzhenie is, ground control station.

Payload representing a telecommunication or radar equipment is placed under the membrane of the balloon in a protective soft sealed fairing aerodynamic form.

The essential characteristics of the tethered balloons are working height and the time of continuous flight. Known tethered balloons ("Puma", C, "Jaguar", PA-1850, PA-12000 and others) up to 12000 cubic meters with a working height of up to 5000 meters and continuous flight until 30 days have significantly lower performance compared to the existing demand. Is known about the development of high-altitude airships ("Berkut", "Sat Strat" and others), which is a balloon platform-media telecommunications equipment, with a working height of 20,000 feet and a continuous flight from 6 months to 5 years. The weak link that limits the working height of the tethered balloon is the cable. When the working height of 20 kilometers required cable length 25-30 kilometers. When this balloon should provide excessive lifting force greater than the force of the wind pressure on the balloon. Maximum pilot height tethered balloon without a payload of up to 17 kilometers above the rope breaks under its own weight and excess under the lending power of the balloon. At the height of 20-25 kilometers wind speed is much less than at lower or higher layers of the atmosphere. However, the specific strength of steel is not sufficient for a cable of this length (e.g., balloon cable diameter 6,5 mm with a breaking load of 39240 Newtons and a weight of 0.15 kg per meter). Maximum operating altitude tethered balloon (the project was never implemented) 9 kilometers, when the volume of the balloon of 220,000 cubic meters.

Low duration of continuous flight known tethered balloons due to the permeability of the membrane and loss of carrier gas. So, for tethered balloon AZ-55 volume 740 cubic meters of gas a new shell (two-ply rubberized fabric) for 24 hours at normal temperature is up to 8 liters per square meter.

The aim of the invention is to increase the duration of the continuous flight of the existing tethered balloons up to 6 months or more and increase the working height for the newly developed tethered balloons up to 20 kilometers in length continuous flight up to 5 years.

To do this, hold the rope of the balloon is in the form of a rope, hose with one or more gas cavities. Gas cavities on Board the balloon is fed carrier gas to Deposit shell AE is estate and gas energy source for electric power generation, supply avionics and payload, and engines, opposing the wind pressure on a balloon and hold it at a given operating point.

The hose cover is calculated based on the required strength of the rope, and the gas cavity is based on the volume of consumed gas.

The design of the cable-hose can be:

- similar to the one of the standard constructions of steel wire when replacing the core of the rope to one or more corrugated or smooth gas pipes and wires on the gas tube of smaller diameter;

or in the form of corrugated or smooth gas tube divided by internal partitions into several gas chambers. Cable-hose may be made of a material that is larger than the specific strength stainless steel. Transition couplings for connection of the cable ends of the hose to the balloon and ground-based gas distribution means and the holding device can be made common or standard method for mechanical (power) and gas (tight) connection.

The design of the tethered balloon with a generator to supply power to the avionics and payload and engine to counteract the wind pressure on a balloon and hold it in a given operating point can be accepted or STD is bound. Or subject to certain features, for example:

- generator and the engine can be running on natural gas;

- gas cavity rope, hose can be connected with a gas cavity of the balloon directly or through the gas distribution device of the balloon;

a separate cavity of the balloon, usually zapomnivshiesya air can be filled with natural gas to create an adequate supply of energy;

- the gas engine can be reactive with automatic control of thrust depending on the wind strength and the gas generator can be integrated with the engine to reduce the overall weight and energy consumption.

A tethered balloon with a rope hose works as follows.

To refill the balloon lifting gas can be used one or two of the gas cavity of the cable-hose. When using a single cavity bearing gas from onshore gas distribution devices served in the cable-hose under pressure in accordance with the mode of transport of the gas.

Using the second gas cavity rope, hose extends.

The mode of circulation of the carrier gas between onshore gas distribution device through the balloon back and forth allows you to change the composition of the carrier gas at different stages of the flight of the balloon (such as the er, heavy/light or expensive/cheap). Ground gas distribution device can separate and purify the components of the carrier gas for reuse. For filing a balloon gas energy can be used only one gas passage of the rope, hose in a similar manner as for the carrier gas.

The use of the engine to counteract the wind pressure on a balloon and hold it in a given operating point can significantly reduce the power load on the cable-hose from the side of the balloon. Material with high specific strength, lifting power, partially compensating the weight of the rope, hose, filled with lighter than air gases, to increase the length of the cable-hose without dropping under its own weight.

Tethered balloon containing the balloon that holds the cable, ground maintenance and a payload, wherein, to increase the time of continuous flight and the working height of the balloon that holds the cable in the form of rope, hose with one or more gas cavities, along which the balloon is fed carrier gas to refill the shell of the balloon and the gas is an energy source for electric power generation, supply avionics and payload, and engines, opposing the wind pressure on a balloon and hold ivalsa it at a given operating point.
