ZeroAvia, a company based in Everett, Washington, has been selected by AFWERX for an SBIR grant to conduct a feasibility study on integrating hydrogen propulsion into Cessna Caravan aircraft, in conjunction with advanced aircraft automation technology. The study aims to address challenges faced by the Department of the Air Force (DAF) through innovative research. ZeroAvia plans to analyze the development of an autonomous aircraft using hydrogen-electric propulsion, which could reduce engine noise, thermal signature, and enhance the performance of electric unmanned aerial vehicles by improving their range, duration, and turnaround time. Hydrogen is highlighted as a promising aviation fuel due to its production simplicity and high energy density, offering the potential for extended flight ranges. To support their exploration of hydrogen propulsion, ZeroAvia will collaborate with Reliable Robotics from Mountain View, California, a specialist in remote operation of aircraft, to investigate relevant autonomous flight systems. ZeroAvia is also working on certifying a 600-kilowatt hydrogen-electric powertrain, ZA600, by converting hydrogen fuel into electricity for the Cessna Caravan, with recent progress marked by receiving FAA G-1 issue paper approval for the electric propulsion system. Val Miftakhov, the founder and CEO of ZeroAvia, expressed optimism about the study's potential benefits, including cost reduction, enhanced capabilities of autonomous air vehicles, and improved operational efficiency in challenging environments. The company's focus on advancing hydrogen propulsion technology aligns with its goal of creating innovative solutions for the aviation sector. The article also mentions the DAF's Open Topic SBIR/STTR program, which has widened the scope of innovations funded by the department, further supporting ZeroAvia's efforts in aviation research and development.
