Ukraine has, for the primary time, despatched into fight a hybrid drone powered by hydrogen gas. In keeping with the builder Skyeton, a variant of its Raybird was deployed for full-scale fight responsibility with the Ukrainian Armed Forces in an energetic warfare zone.
Hydrogen-powered drones aren’t precisely new. They have been round for nearly 20 years, although earlier examples have been primarily expertise demonstrators and experimental prototypes. Normally, these have been meant as long-endurance, high-altitude craft, although an Israeli-US system known as Heven AeroTech Z1 is meant for front-line missions, however this has but to be deployed.
In keeping with Skyeton, the hydrogen variant of the Raybird has been modified to accommodate the brand new gas system and to supply sufficient room and distribute weight for the hydrogen tanks, that are bigger than their hydrocarbon gas equivalents for inside combustion engines.

As a result of the Raybird is a hybrid, the hydrogen is used to generate electrical energy whereas electrical motors present thrust. With a takeoff weight of 51 lb (23 kg), a wingspan of as much as 15 ft (4.7 m) and a payload of as much as 22 lb (10 kg), the Raybird has a cruising velocity of 68 mph (110 km/h) and an endurance of 12 hours. The hybrid system signifies that craft is quieter in comparison with a four-stroke engine and has a negligible warmth signature, although its altitude is restricted to 18,000 ft (5,500 m).
In keeping with the corporate, the Raybird is just not armed. As a substitute, it carries radar and different sensors for long-range reconnaissance missions. As well as, the design lends itself to mass manufacturing. Hydrogen is supplied by interchangeable cartridges or subject producing items.
“We have now transformed two years of laboratory testing into a brand new plane idea: it’s the identical class and weight, however a very redesigned idea based mostly on electrical propulsion,” mentioned Roman Knyazhenko, CEO of Skyeton. “Hydrogen gas is an answer that permits us to mix all the benefits of an electrical motor – excessive reliability, energy, and ease of upkeep – with the long-duration steady flight that may be a hallmark of our UAV. Sustaining a steadiness of those traits is important for us, because the Raybird performs complicated deep reconnaissance duties utilizing high-tech payloads, and the typical length of such missions exceeds 10 hours.”
