Siemens-FlyEco Magnus eFusion


The Siemens-FlyEco Magnus eFusion is a German hybrid diesel-electric aircraft that was designed by Siemens and FlyEco, introduced at the AERO Friedrichshafen show in 2018. The aircraft is intended for series production as a ready-to-fly design.
The design was first flown on 11 April 2018 in Hungary. On 31 May 2018, the prototype crashed in Hungary, while on a training flight, killing its two occupants.

Design and development

The aircraft features a cantilever low-wing, a two-seats-in-side-by-side configuration enclosed cockpit under a bubble canopy, fixed tricycle landing gear and a single engine in tractor configuration.
The aircraft is made from composites. The power train consists of a Siemens SP55D electric motor which will be powered by batteries for take-off and landing. A FlyEco three-cylinder diesel engine, derived from a Smart Car engine, with common rail injection and electronic controls, will recharge the batteries in flight for extended range.

Accidents and incidents

The prototype crashed in Hungary on 31 May 2018 killing both occupants. The aircraft was on a training flight at the time. No cause of the accident has been determined, but investigation revealed that it was not due to an in-flight battery fire, although there was a post-crash fire.
