Stralis Aircraft has achieved a significant milestone in the realm of aviation by successfully conducting the Southern Hemisphere's first hydrogen-electric propeller spin test at Brisbane Airport. The ground-demonstrator aircraft, affectionately known as 'Clyde,' underwent this test, marking a crucial step towards emission-free flight. The test, powered by hydrogen-electric propulsion, resulted in the emission of only water vapor, demonstrating the environmental benefits of this technology. Stralis' CEO, Bob Criner, expressed pride in this accomplishment, highlighting the collaborative efforts and upskilling involved. This achievement not only sets the foundation for future hydrogen-electric flights but also signifies progress towards sustainable aviation practices. Skytrans Airlines, a key partner, applauded Stralis for this advancement, emphasizing the importance of emission-free aviation. Brisbane Airport, where the test took place, also played a pivotal role in enabling this groundbreaking test, showcasing the safety and viability of hydrogen as a propulsion method. With grant support from the Australian government, Stralis aims to continue its innovative work in the aviation sector, with plans to conduct Australia's first hydrogen-electric flight next year. This successful test not only signifies technological progress but also underscores the industry's commitment to sustainability and green energy in aviation.
