In a recent article Airbus (Helicopters) CEO Guillaume Faury spoke of a back-up electric motor which is going into production:
Depending on just how much energy this motor will deliver, one imagines that it would indeed be welcome in various emergency scenarios.
One wonders though what sort of battery array will be employed to store this energy. Presumably they've come-up with something 'reasonably' light in terms of weight?
One concept demonstrator now being developed into a product is the electric backup motor. It was tested on an AS350 Ecureuil single in 2011.
Improvements in motors and electric energy storage have made a sound business case for such hybrid power, Faury said.
While not powerful enough to serve as a second engine, the system would make autorotation safer by countering any rpm drop and providing some power in the flare.
