Beyond Aero has revealed the refined concept for its BYA-1 light jet, focusing on key engineering advancements in hydrogen propulsion and certification. The BYA-1 is the first electric light jet specifically crafted for hydrogen propulsion, with design improvements such as a battery-free hydrogen fuel cell system, gaseous hydrogen tank placement above the wing box, and a thermal management system for electric ducted fans. These enhancements not only enhance performance but also reduce maintenance and operational costs with an all-electric powertrain and modular engine swap system. The aircraft is expected to bring significant cost savings, with hydrogen fuel projected to cut fuel costs by 65% compared to Power-to-Liquid SAFs by 2025 and 17% compared to Jet A-1 by 2030. Beyond Aero has garnered support from an expert advisory committee of aerospace professionals, endorsing the technical viability of the aircraft and its readiness for certification and market acceptance. The BYA-1 boasts impressive specifications, with an operational range of 800 NM plus NBAA reserves, meeting the demands of over 80% of current European flight routes. Its design emphasizes operational flexibility, with features like elliptical windows, low-noise electric propulsion, and advanced acoustic insulation for enhanced passenger comfort. Beyond Aero is actively collaborating with EASA to ensure regulatory compliance and safety standards for its hydrogen-powered aircraft. The company is pioneering hydrogen-electric certification, working closely with EASA to establish specific conditions tailored to this innovative technology, setting a precedent for the aviation industry's future. The collaboration aims to enable the safe and efficient adoption of hydrogen propulsion in aviation, showcasing a positive sentiment towards the advancement of eco-friendly aviation solutions.
