Rolls-Royce Reveals Turbogenerator

In an announcement at the ILA Berlin Air Show on June 22, Rolls-Royce revealed a design for a turbogenerator for hybrid-electric applications, namely eVTOL and eSTOL aircraft. The turbogenerator will be scaled to serve a power range of between 500 and 1,200 kW and be capable of either recharging batteries after take-off or providing power directly to propellers, allowing aircraft to switch between electric or sustainable fuel power sources in flight. The company expects to begin initial tests of the turbogenerator this year and hopes to introduce it for service in 2027. The German Ministry of Economic Affairs and Climate Action is providing funding for the development of the project.
