Swiss business jet manufacturer Sirius has undergone a significant transformation by rebranding itself as Stellar Aircraft and moving its headquarters to the USA, specifically Delaware. The company's strategic pivot towards hydrogen-powered aviation is evident with the introduction of the Stellar Jet, a clean-sheet eVTOL design. Stellar Aircraft aims to showcase its commitment to innovation and sustainability by developing cutting-edge technologies like the hydrogen-electric powertrain for the Stellar Jet. The CEO, Alexey Popov, highlighted the immense potential in the US market and the company's vision to lead the aviation industry with transformative solutions. The Stellar Jet's performance projections, including its cruise altitude of 25,000 feet, speed of 280 knots, and low noise emissions, signify a promising future in eco-friendly aviation. Stellar Aircraft is set to disclose the results of performance validation tests for its proprietary hydrogen fuel tank in February, further solidifying its position as a pioneering force in the hydrogen aviation sector.
