Umbra Group is developing linear jam-tolerant actuators, which have a mechanism that can resolve a failure. Supernal is also working with Qarbon and GKN.

The five-seat Bell 505 has become the world’s first single engine helicopter to fly using 100 per cent sustainable aviation fuel.

GKN will design, build and integrate the EWIS for Lilium’s type-conforming aircraft and Aeronamic will make the fan for its jet propulsion system. Final assembly of the Lilium Jet is due to start later this year.
