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 featured a cantilever low-wing, a two-seat side-by-side configuration enclosed cockpit under a bubble canopy, fixed tricycle landing gear, and a single engine in tractor configuration.The aircraft was made from composites. The power train consisted of a Siemens SP55D electric motor which was intended to 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, was intended to recharge the batteries in flight for extended range.
