Piasecki Aircraft is set to modify an ultralight helicopter to incorporate a hydrogen-electric propulsion system for testing purposes. The aircraft chosen for this innovation is the German-built EDM Aerotech Coax 2D, known for its two-seat coaxial-rotor design. The objective of this project is to showcase the viability and efficiency of hydrogen-electric technology in aviation. By aiming to have the piloted technology demonstrator operational by the end of the year, Piasecki is taking a significant step towards advancing eco-friendly propulsion systems in the aerospace industry. This initiative is crucial not only for the company but also for the broader aviation, aerospace, and defense sectors, as it highlights the potential of hydrogen in driving future technological advancements.
