Aerospace & Mobility
Traveling and transporting goods, be it on land, on water or in the air, should be efficient and resource-saving, and in the future without CO2 emissions. B&B-AGEMA works with well-known international partners on the development of hydrogen-powered jet engines. Safe and low-emission hydrogen combustion is a core technology in the development of such engines, for which B&B-AGEMA has the competence, experience and knowledge. Hybrid drive systems with electric motors using hydrogen gas turbines to generate electricity can play an important role in the future, especially for flight applications such as air taxis (e.g. electric-driven Vertical Take-Off and Landing aircrafts, eVTOLs) and transport drones.
Lightweight Hydrogen Power Unit (PUMAc)
For eVTOL applications B&B-AGEMA has performed a comprehensive concept study for a lightweight gas turbine power unit with a target power-to-weight ratio of 4 kW/kg and dual fuel technology. Besides conventional kerosene combustion, the power unit is intended to be powered with 100% Hydrogen for CO2-free operation based on an experienced Hydrogen combustion technology. The power unit is set to combine high efficient turbomachinery concepts with new materials (e.g. Ti-Al blades/vanes) and advanced manufacturing technologies, e.g. additive manufacturing for a most efficient cooled first turbine stage by realizing new coling concepts.
Hydrogen Fueled Aircraft Engines
B&B-AGEMA collaborates with the Aerospace Company of Kawasaki Heavy Industries on the combustor development of Hydrogen-fueled aircraft engines.
At the International Gas Turbine Congress (IGTC) 2023 in Kyoto Kawasaki Heavy Industries and B&B-AGEMA presented the first results of numerical investigations based on high level LES combustion simulations for an aeroengine MicroMix combustor (Abstract).
