Helikite Aerostat Videos

Helikites are one of the most popular aerostat designs and are widely used by the scientific community, military, photographers, geographers, police, first responders. Helikites are used by telecoms companies to lift 4G and 5G base stations for areas without cellphone coverage.

Helikites aerostats combination of a helium balloon and a kite to form a single, aerodynamically sound, stable tethered aircraft that has many uses in military surveillance, environmental research and communications.

The patented Helikite design exploits both wind and helium for its lift. Helikites are considered the most stable, energy and cost-efficient aerostats available. This gives Helikites various advantages over traditional aerostats.

Traditional aerostats need to utilize relatively low-lift helium gas to combat high winds, which means they need to have a lot of gas to cope and so are very large, unwieldy and costly.

Helikites exploit wind lift so they only need to be a fraction of the size of traditional aerostats in order to operate in high winds. Helikites can fly many times higher altitude than traditional aerostats of the same size. Being smaller, with fewer construction seams, means Helikites have minimal problems with gas leakage compared to traditional aerostats, therefore  Helikites use far less helium.

Helikites do not need ballonets and so are simpler in construction than traditional aerostats and Helikites do not need any electrical power to keep them airborne.

Helikites are also extremely stable and so are good aerial platforms for cameras or scientific instruments. Small Helikites will fly in all weathers, so these sizes are popular as they are very reliable but still easy to handle and do not require large expensive winches. Helikites can be small enough to fit fully inflated in a car but they can also be made large if heavy payloads are required to be flown to high altitudes.

Helikites range in size from 1 metre (gas volume 0.13 m3) with a pure helium lift of 30g, up to 14 metres (gas volume 250m3) able to lift 117 kg. Small Helikites can fly up to altitudes of 1,000 ft, and medium-sized Helikites up to altitudes of 13,000 ft, while large Helikites can achieve over 7,000 ft.

Below are some videos of the thousands of Helikites being used around the world.

Helikites:

Using a combination of a Helikite aerostats fitted with  communications transeivers offers for a rapidly deployable communications network. Helikite aerostats are persistent, all-weather, miniature aerostats used and proven by governments and communication specialists worldwide.

The Helikite is a type of hybrid kite-balloon. The Helikite comprises a combination of a helium balloon and kite to form a single, aerodynamically sound, unmanned, tethered aircraft, that exploits helium for its lift and harnesses wind for stability and lift.
The Helikite comprises a semi-rigid helium-filled balloon, having a rigid carbon-fibre spine, with the balloon shaped aerodynamically. The balloon is generally oblate-spheroid in shape in shape although this is not essential. Solid spars provide attachment points for payload equipment such as 4G communications or video cameras.


In most winds the aerodynamic lift is greater than the aerostatic lift from the helium.


The Helikite design is intended for all-weather, high-altitude operation. The round, stubby shape allows it to be flown in any weather or for altitudes up to 7000 ft. In wind, both the main aerodynamic lift and the aerostatic lift are at the front, while the spar weight and keel are at the stern. Therefore a Helikite remains stable in relatively high winds


A Helikite is a new type of tethered aerostat with its own official classification, distinct from any type of balloon.
The US Customs classifies a Helikite as "other non-powered aircraft", while the British Civil Aviation Authority's Air Navigation Order has created its own classification as "Helikites" as distinct from "kites" and "balloons".


Customs authorities classify the Helikite as a type of kite because of the considerable positive aerodynamic uplift in wind.
Thousands of Helikites have been operated worldwide, over both land and sea.
Helikites are used for aerial photography antennas, radio-relay, advertising, agricultural bird-control, position marking, and meteorology.  The military also use Helikites as jungle marker balloons, for lifting radio-relays, and raising surveillance equipment.
Helikites are the only compact aerostat capable of reliably operating at sea. For this reason small, rapid-response surveillance Helikites are part of the emergency oil-spill response system of Scandinavia for operations in the arctic ocean.


Due to their stability, Helikites are capable of successfully operating non-gyrostabilised cameras, leading to wide use by photographers and cameramen.


A small Helikite may be used as a "personal aerostat" that is small enough for one person to easily operate and yet will fly high in bad weather.


The British Army military Helikite surveillance system has 34 m³ volume and lifts a lightweight gyro camera with both E/O and IR capabilities. The US surveillance Helikites are 75m3 and carries a larger gyro camera system and targeting equipment. These aerostats outperform a conventional aerostat of twice the size. These Helikites can lift surveillance equipment above the range of small arms fire, effectively making Helikites unassailable to most common threats.


Operators include: US Navy, US Air Force, US Marines, US Navy Seals, British Army, Royal Marines, Australian Defence Force, Lockheed Martin, DSTL, QinetiQ, CENETIX, Thales, British Antarctic Survey, Norway Oil-spill Response, Sandia National Laboratories, Frauenhofer Institute, CSIR, NIWA

Helikite Aerostats for Surveillance

 

Helikites are commonly used special event and perimeter observation; payloads include communications as well as day/night cameras with long range capabilities. Helikites are quickly and easily transported even to remote areas around the world. The rapid deployment of Helikites makes ideal solution for surveillance in large and dangerous areas where environmental conditions may not be favourable. Helikites excel in harsh and windy conditions. Inner balloons on Desert Star Helikites can be changed in minutes after being shot at and are also easily repaired.

Helikite Aerostats for Military Defence

 

Helikite are tethered aerostats that can be equipped with multi-mission sensors to provide long endurance intelligence, surveillance, reconnaissance and communications in support of coalition forces. They are also used for communication relays to and from unmanned vehicles. Helikites have been used around the world extensively  by UK and USA Military forces for well over 20 years.

DIGITAL OPPORTUNITIES AND CHALLENGES

Military digital communications using high frequency radio waves are becoming more and more important as the advantages to the warfighter of ready access to digitally transmitted data such as visual charts, GPS locations , text messaging and video images become apparent. Sensors relying on digital comms can protect fleets from missile attack, clear minefields and track submarines. Significantly, digitalisation now also allows radio traffic to differentiate between numerous unmanned vehicles, giving a vast new unmanned force to those who learn to how to exploit this potential.

However, a problem emerges when high frequency radio waves wish to be exploited. The user discovers that digital radio waves travel in straight lines, whereas the Earth is curved and has hills and mountains on the land which stop radio waves travelling between radio handsets. This inevitably results in loss of signal. Perfect radio line-of-sight is required. Also, high frequency digital radio waves are attenuated to a greater extent than low frequency waves by things such as low-lying vegetation, buildings, waves, salt spray and precipitation. It is found that the movement of small boats into wave troughs and irregular movements of antennas reduces the theoretical radio range considerably. In practice, a broadband high-frequency radio signal that could theoretically travel 30 NM may in fact only be received reliably 10 NM away.

TWO PART SOLUTION

The answer to this problem entails the mastery of two aspects of digital radio propagation.
1. The manufacture of excellent digital radio relays
2. The positioning of them at high altitude.

Numerous excellent digital radio-relays now exist in the form of superb MANET radios and small cell-phone base stations. The problem that remains is the positioning of these relays at useful altitude, when required, in the right place, easily and cheaply – in all weathers. This is a huge problem, and one that the militaries of the world have spent billions of dollars trying to overcome mainly by use of satellites. However, satellites are relatively low bandwidth, inflexible, prone to attenuation by vegetation and incapable of ever realising the bandwidth requirements of swarms of unmanned vehicles.

 

The solution to this high-altitude positioning problem is fundamental to the progress of high bandwidth military radio communications. If it is not grasped then digital communications and the military operations relying on it, will forever remain either relatively low-bandwidth satellite based, or short-range and vulnerable mast based.

Militaries unable to put radio-relays into the air will be unable to compete with those that can do so. So, airborne platforms are the second essential pillar of military communications.

THE WORLD’S BEST MILITARY AIRBORNE COMMUNICATIONS PLATFORM

High-altitude, all-weather Helikite aerostats are the world’s most reliable and economical method of lifting mass into the sky ever devised. All other methods are approximately 200 times more expensive. Tough, double-lined Desert Star Helikites are very well suited to military life and have been extensively used in conflicts areas worldwide including Afghanistan, Middle East, Africa, and South America. Both at sea and on land.

Helikites lifting MANET radios or 4G relays create an extensive area in which there is full broadband radio communications for personnel, ships, sensors and unmanned vehicles - limited only by the numbers of Helikites and radios available.

Helikites have proven they can provide a simple, reliable way of greatly increasing military radio-range and bandwidth at very little cost. No extra ships, masts, vehicles, aircraft or inter-service co-operation is required. Helikites are significant force multipliers that can immediately increase reduce exposure to risk for personnel so reducing casualties.

In Ukraine, Helikites easily overcome the worlds most sophisticated jamming by lifting radio-relays high into the sky where Russian ground-based jammers are largely ineffective.

Ultimately the Helikites’ greatest virtue is its ability to allow network-centric war-fighters far removed from the battlefield, to directly help their colleagues at sea via the remote operation of unmanned vehicles, mines, munitions and sensors.

Helikites plus MANET radios and 4G, allow a vast previously untapped, worldwide network, of thousands of human and computer resources, to be concentrated into the centre of the battlefield in an instant. This is force-multiplication on an industrial scale.
