Hybrid

HYBRID in aviation is the combination of conventional engines, piston or turbine, with an electric drive systems.

If the conventional engine is SAF (Sustainable Aviation fuel) capable, the result is a “net-zero” CO2 solution optimised for the mission profile.

The key to success is the software combining the control abilities of the conventional engine with the requirements of the electric drive and the battery management.

RED worked closely with US based company Ampaire Inc. to realize the first RED A03 hybrid system, where Ampaire is responsible for the electrical integration of the hybrid side.

Ampaire Inc. sucessfully made the maidenflight with a RED A03 Hybrid System in November 2022. Please feel free to contact us for further details.

The electric side of the concept provides the extrapower required for take-off. Three ground infrastructure scenarios are dominating the options:

    1. There is no charging infrastructure on the target airport. In this scenario the batteries are recharged during cruise flight and the hybrid aircraft may take-off from the airport combining electric and conventional power.

    1. There is limited charging infrastructure on the target airport or the mission requires extra energy. The inflight charging may be reduced and the batteries are charged on the ground. 

    1. The target airport offers perfect charging infrastructure. The hybrid aircraft is landing with the batteries discharged. Ground infrastructure allows charging until the hybrid aircraft is ready to go again.
