  • Publication number: 20250206458
    Abstract: A dual fuel propulsion system is disclosed. The aircraft is capable of performing a flight mission during which the first or the second selectively useable. The aircraft comprises: at least one internal combustion engine capable of generating propulsive thrust using selectively a first kerosene based jet fuel and a second liquid hydrogen fuel, and two independent sets of fuel systems, including a first fuel system feeding the first fuel from a first set of fuel storage tanks to the internal combustion engine and a second fuel system feeding the second fuel from a second set of fuel storage tanks to the internal combustion engine. Both sets of fuel storage tanks host the required fuel for the flight mission plus reserve fuel.

  • Publication number: 20230348081
    Abstract: The invention relates to a hybrid electric drive system (10) for multi-motor aircraft (20). The hybrid electric drive system comprises at least a first and a second hybrid electric drive unit (31, 32), each of which comprises: an internal combustion engine (41, 42), a motor-generator unit (71, 72) and a gear box (51, 52) for transmitting drive power to a propeller (61, 62). In order to supply the motor-generator units (71, 72) with electrical energy, the drive system (10) has a fuel cell (73), which in turn is supplied with hydrogen by means of a fuel tank (74). In the fuel cell (73), hydrogen is converted into electricity, which then supplies the motor-generator unit (71, 72) with electrical power by means of the transmission device (80) and power converters (81) and (82), in order to drive the propellers (61, 62).
