Diamond HK36 Super Dimona — Other Documents

This document is a technical thesis focused on the design and performance of hydrogen fuel cell aircraft, specifically targeting regional travel. It discusses the challenges and methodologies involved in conceptualizing and simulating aircraft powered by hydrogen fuel cells. The author, Christian Svensson, presents findings from various studies, including the integration of fuel cell systems into existing aircraft designs, such as the Diamond HK36 Super Dimona. The thesis emphasizes the potential of hydrogen as a sustainable aviation fuel and explores the implications for future aircraft designs, particularly in the context of increasing passenger demand and environmental concerns. The document is intended for engineers, researchers, and aviation enthusiasts interested in the future of aviation technology and sustainable practices.

• The Diamond HK36 Super Dimona was successfully flown using a hydrogen fuel cell system, demonstrating the feasibility of this technology in aviation.
• The maximum take-off weight (MTOW) of the modified HK36 Super Dimona was increased to 870 kg due to the new propulsion system.
• The fuel cell system used in the HK36 Super Dimona had a maximum power output of 24 kW, powered by hydrogen from a 350 bar tank.
• Hydrogen fuel cells offer a higher efficiency (45-60%) compared to traditional turboprop engines (20-30%).
• Cryogenic storage of hydrogen is essential for maximizing energy density, requiring specialized insulated pressure vessels.
