RED Aircraft and Helix Launch Hybrid Generator for Aviation Applications
The RED A03 Series Hybrid Generator offers up to 380kW electrical output with a weight of 350kg, enhancing aviation efficiency. This technology aims to reduce fuel consumption and emissions significantly compared to traditional systems.

The RED A03 Series Hybrid Generator, developed by RED Aircraft and Helix, combines the RED A03 V12 diesel engine with the Helix SPX177-137D motor. This generator can deliver 380kW of peak electrical power with a dry weight of 350kg, revolutionizing aviation power generation.
The SPX177-137D motor weighs only 21.7kg and achieves a peak output of 420kW, demonstrating a power density unmatched in current auxiliary power units. Fuel efficiency is improved, yielding 50% savings compared to turbine engines and reducing CO2 emissions.
This innovation is particularly suited for eVTOLs and urban air taxis, addressing noise limitations at airports. Further variants using RED Aircraft's engines are anticipated.
