NEWBORN focuses on development and demonstration of the TRL 4 ground demonstrator of the overall propulsion system using fuel cells technology for electricity generation. The fuel cell power source technology will consist of 1MW modules, which can be paralleled to exceed the 3 MW power levels defined by the CAJU call. The consortium plans to market the technology early aboard the CS-23 19-pax commuter aircraft – 2 systems, total system take-off power of ~2 MW.
The ambition of the project is to achieve an overall propulsion system efficiency of 50% by the end of the project, calculated as a ratio of energy on the propeller shaft to the hydrogen lower heating value.
The project will demonstrate widely scalable fuel cell power source technology with a power density of >1.2 kW/kg and high stack power density. Technologies will be adaptable to different maximum flight altitudes of ≤ FL250 and ≤FL450, scalable down and reusable for secondary power in SMR flying altitudes by the end of the project. An innovative cryogenic tank concept will be integrated, demonstrating a high gravimetric index for the CS-23 aircraft and scalable up to 50% for regional aircraft. The project will also address high power density high voltage energy conversion, propulsion systems, and the next generation microtube heat exchangers, along with an accurate digital twin of the overall system. NEWBORN will develop a technology demonstrator prepared for flight demonstration in the future.
