Periodic Reporting for period 2 - HEAVEN (High powEr density FC System for Aerial Passenger VEhicle fueled by liquid HydrogeN)
Reporting period: 2020-07-01 to 2021-06-30
This FC based powertrain will be developed and used for in-flight demonstrations on the experimental aircraft HY4 (2-4 PAX) to showcase aircraft relevant power density and range of the powertrain. The core value of HEAVEN is to transfer FC and cryogenic hydrogen storage technology from automotive and space technology to aircraft application, to advance it further and to build up technological know-how and use flight test data to validate the performance, range, efficiency and emission reduction capabilities of above technologies. This will allow making conclusions about the suitability of these solutions towards Air taxi and regional aircraft scale zero-emission hydrogen-FC-powered solutions.
While HEAVEN high power and energy density FC-hybrid propulsion solution can be adapted to larger aircraft, testing the technology on large aircraft would first require massive investments in megawatt class ultra-lightweight engines, bringing delays to this perspective development.
By implementing the technological solutions first on small aircraft, which have favorable power-demands to conduct flight testing now, this narrows the horizon of commercial exploitation of the technology to years 2020-2030. Moreover, the scalability of the fuel cell system and the powertrain into small and bigger aircrafts as well as the extrapolation of the technology to UAV applications will be analyzed by using simulations during the execution of the project, providing inputs to the design activities to design towards the full modularity.
