Hybrid systems in aviation

HYBRID in aviation is the combination of conventional engines and electric drive systems.

If the conventional side is SAF capable, the result is a “net-zero” solution optimised for the mission profile.

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

Ampaire Inc. had it’s maidenflight with such a system in November 2022. Please feel free to ask for 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. This also is the solution for fast turn-around missions.
  2. 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. 
  3. 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. This is the maximum payload and airspeed mission.
