The Allsopp Helikite is a type of kite-balloon or kytoon designed by Sandy Allsopp in the UK in 1993. The Helikite comprises a combination of a helium balloon and a kite to form a single, aerodynamically sound, tethered aircraft, that utilizes both wind and helium for its lift. Design The Helikite, created by Allsopp Helikites Ltd., comprises a semi-rigid helium-filled balloon, having a rigid carbon-fiber spine, with the balloon shaped aerodynamically. The balloon is generally oblate-spheroid in shape in which solid spars provide attachment points for payload equipment. 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 operations. The round, stubby shape allows it to be flown in any weather or for altitudes up to 7000ft. 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. 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 expensive. Because Helikites utilize wind lift, they only need to be a fraction of the size of traditional aerostats in order to operate in high winds. Helikites fly at many times higher altitudes 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, so Helikites use far less helium. Helikites do not need ballonets and so are simpler in construction than traditional aerostats, as Helikites do not need constant electrical power to keep them airborne. Helikites are also extremely stable and so are good aerial platforms for cameras or scientific instruments. Tiny 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 higher altitudes. Helikites are one of the most popular aerostat designs and are widely used by the scientific community, military, photographers, geographers, police, and first responders. Helikites are used by telecom companies to lift 4G and 5G base stations for areas without
