EXCEPTIONAL AERIAL PLATFORMS
Helikites are by far the most inexpensive and reliable airborne platforms in the world. Competing airborne platforms such as aircraft , balloon, blimps, kites, helicopters or UAV's are either very unreliable in difficult weather conditions, or up to 200 times more expensive to operate per hour.
Lifting things into the air for short periods can be done quite easily with aircraft other than Helikites, however, staying in the air for a few minutes or hours is completely different to staying in the air for days or weeks. This is because when an aircraft is in the air for a short period of time unusual events such as extreme weather or wear seldom happen, so these aircraft are unable to cope with these events. Longterm unusual events become inevitable and then these short term airborne platforms crash. Helikites are massively over-engineered to cope with unusual airborne events and so fly through them unscathed. For example, when the US army did comparative trial or aerostats for use in Afghanistan they flew them for many weeks in the Arizona desert, during the trials, dust devils went through the aerostats positions destroying all the aerostats except the Helikites that flew through them undamaged. This is why the Helikites were picked by the Rapid Equipping Force for use in Afghanistan. Dust devils are not common but if aircraft are flying long enough in hot districts, contact is inevitable sooner or later.
Helikites are exceptionally steady in flight compared to any other aircraft. This is critical for lifting cameras and radios where the position of the lense and the antenna is significant. Helikites have custom mounts for cameras, weather sensors, radios and antennas to ensure strong and safe attachment to the aircraft. Other aerostats often only dangle cameras from cords which is not steady or safe.
LIFTING CAMERAS & SENSORS
Many people buy Helikites to lift cameras into the sky because of the stability compared to other aerostats and blimps.
Cameras need to be kept:
-
Steady
-
In Correct Position to give all round vision
-
At Correct Horizontal Attitude
Most other aerostat designs subject their cameras to be dangled on the ends of loose lines hanging below the aerostat. This is not good enough, especially in the high winds, because loose lines cannot keep payload steady enough. Unsteady cameras give very poor performance and may well upset the flight of the aerostat.
Cameras need to be kept steady whilst also having a good field of view below the Helikite. Also, the camera must not interfere with the safe ground-handling of the aerostat.
So Allsopp Helikites Ltd has designed a revolutionary new solid and reliable airborne camera attachment system for still and video cameras. Cameras are not left dangling in the air, but instead are bolted firmly to a strong monopod on the stiffened keel. A superb “Steady-Cam” Damped Pendulum Mount can be attached to the monopod to keep cameras automatically in line with the horizon. These camera attachment systems allow the camera a 360 degree view of the ground whilst not compromising the steady flight of the Helikite, even in high winds. Ground handling is safe, and expensive cameras are protected from the ground during launch and recovery.

Stiff Carbon-Fibre Rods – Provides solid mounting points, reduces vibration and swaying.
Strong Aluminium Bar Monopod – Stiff camera mount easily detachable from carbon-fibre rods.
Damped Pendulum Camera Mount – Allows camera to smoothly hold itself horizontal with the horizon.
Excellent 360 degree view of the ground for camera.
Lightweight cameras can also be placed with care around the circumference of the balloon to give all round vision if required. Allsopp Helikites Ltd also have proprietary methods of placing cameras on the flying line, which is sometimes useful.
Sensors such as wind meters and radar can be attached in the same way as cameras.
LIFTING RADIOS, ANTENNAS & POWER
Radio-relay trials have consistently shown that Helikites are by far the best persistent and reliable airborne radio relay platform in the world. This is not just due to their excellent flying performance, but also due to the ease at which radios, batteries and antennas can be steadily positioned in both altitude and attitude in order to give optimum propagation and reception of high bandwidth digital radio. Helikites are hugely sensitive interceptors of radio traffic and also superb at propagating clear and powerful radio signals over the horizon. Helikites also are excellent at holding radios in the best position for the most effective jamming of air, ground and satellite radio signals. Fibre-optic cables running up the line facilitate the operation of high altitude active radar and passive sensors that give over 100 miles range. When required, Helikites can rapidly, easily and permanently dominate much of the electro-magnetic radio spectrum within their line of sight.
Webbing straps secure radio, radar and electronic payloads safe and dry in the space between the kite and the balloon cover. Even heavy payloads cause no instability in this position.
Antennas that are lightweight can be attached almost anywhere. Behind the balloon is generally the most convenient for electronics and also for radar domes or radar reflectors.
It is important to note that the angle of attitude of a Helikite is the same with or without wind, due to its natural stern heavy displacement. This feature is exceedingly useful for radio relay operations because it ensures that antennas are kept vertical whatever the weather. This is the reason that Helikites outperform all other small aerostats, UAV’s, manned aircraft and even tall masts in radio-propagation and reception performance.
Powerful lithium batteries are held in a pouch at the top of the keel where they are easily accessible for quick changes.
Power can be run up the flying line if required.
