Hybrid-Electric Propulsion – The Reason Why
In early March, Dufour Aerospace put the hybrid unit, consisting of a two-cylinder engine from Suter Industries, a generator from Plettenberg and our own digital control hardware, into operation for the first time on its own test bench. Some further optimisation and testing work still remains to be done before the drive can then be installed on the Aero2 X2.3 prototype. Continue reading

Propeller Advance Paves Way for Quiet, Efficient Electric Aviation
Electrification is seen as having an important role to play in the fossil-free aviation of tomorrow. But electric aviation is battling a dilemma: the more energy-efficient an electric aircraft is, the noisier it gets. Now, researchers at Chalmers University of Technology, Sweden, have developed a propeller design optimisation method that paves the way for quiet, efficient electric aviation. Continue reading
