UVa’s Sustinere design for a 50-seat jet eschews batteries in favor of a turboelectric distributed propulsion (TeDP) concept – two 2,500shp turboshaft engines under the wing generating electrical power to drive six 3,300lb-thrust fans arrayed in a duct that wraps around the upper fuselage.

The EADS IW concept uses a single large turbine engine to generate electricity to power six ducted fans that provide thrust. This allows propulsive and thermal efficiency to be optimized separately. The turbine engine can be optimized for thermal efficiency (turning fuel into shaft power) while the ducted fans increase effective bypass ratio and therefore propulsion efficient (turning shaft power into thrust).

Two years after Honeywell and Safran announced plans to develop an electric-drive system, the team is preparing to demonstrate a proof-of-concept system on an Airbus A320 at this year’s Paris air show.

The result of close collaborations with Finmeccanica companies – Selex ES, Ansaldo Breda, and Ansaldo Energia – and partner companies from Italy, UK, U.S. and Japan, the aircraft embeds some unuque features: aesthetically pleasing styling and aerodynamically unique tiltrotor configuration; carbon graphite exterior surfaces; High-Integrity Flight Control Computer and Actuator Control Unit; custom produced electric motor inverter and motor control algorithm; axial flux permanent magnet electric motors.
