EVERETT, Wash. - magniX, an electric aviation company in Everett, Wash., has unveiled its HeliStorm electric engine series, which is designed specifically for helicopters. The lightweight, high-speed engines are suited for a range of rotorcraft, from light single-engine helicopters to larger hybrid-electric twin-engine models and airborne power generation applications.
Combined with magniX’s Samson battery system, the HeliStorm series provides a comprehensive electric propulsion solution for rotorcraft. The first model in the lineup delivers peak power of 330kW while weighing just 75 kilograms.
The HeliStorm engines are engineered to operate at speeds of 6,000 to 7,000 RPM. They offer a significantly lighter alternative to turbine engines in similar aircraft. The system is designed with scalable power output ranges. It features industry-leading fault handling capabilities. Additionally, the engines provide airborne power generation, which extends the range of hybrid-electric platforms.
Launching the Electric Helicopter Age
magniX has drawn on its extensive flight test experience, including two separate integrations with Robinson R44 helicopters, to develop the HeliStorm engines. The first electric R44 helicopter powered by a magniX motor took flight on June 4, 2022, at Los Alamitos Army Airfield in California. This milestone marked a major step forward in electric aviation, leading to the world’s first point-to-point flight of an electric helicopter.
