Jetcruzer International has emerged as the first customer to purchase ZeroAvia's 600kW electric propulsion system (EPS) for the development of the Jetcruzer 500E, a six-seat hydrogen-electric aircraft. ZeroAvia, a pioneer in sustainable aviation, has already garnered significant interest with over 2,000 pre-orders for its hydrogen-electric powertrains, mainly from commercial airlines. The recent sale to Jetcruzer marks a crucial milestone in supporting the advancement of the all-electric Jetcruzer 500E, set to revolutionize sustainable aviation. Innovating in the field, ZeroAvia introduced a new component offering to meet the rising demand for innovative electric air transport solutions. The 600kW EPS, featuring proprietary inverter and electric motor technology, obtained a Federal Aviation Administration (FAA) G-1 issue paper, a vital step towards certification. This system is designed to offer highly efficient electric engines with exceptional fault tolerance. The 600kW EPS is destined to power the upcoming Jetcruzer 500E electric aircraft, scheduled for an entry into service by 2028, to be succeeded by the 1250E in 2030. With a strong emphasis on sustainability, the 500E is poised to be among the first aircraft to operate with an all-electric propulsion system, showcasing a commitment to eco-friendly aviation practices. Sergey Kiselev, ZeroAvia's chief business officer, expressed enthusiasm for the collaboration with Jetcruzer, highlighting the significance of the sale in supporting a project with a rich history and promising future. By focusing on deep vertical integration in powertrain technology development, ZeroAvia has accumulated valuable intellectual property and a portfolio of innovative fuel cell and electric propulsion components. ZeroAvia's dedication to advancing sustainable aviation is evident in its rigorous testing of hydrogen-electric engines, including successful flights of the ZA600 engine on a Dornier 228 aircraft and ground tests for the ZA2000 system tailored for larger planes. The Jetcruzer 500E project serves as a beacon of collaboration for sustainable aviation advancements in a rapidly evolving industry.
