Aero 146E is a hybrid-electric aircraft being developed by a partnership of Aero, SAAB and VOLISAN. Announced on 28 November 2015, it follows previous electric flight demonstrators towards sustainable transport for the MOZ. A BAe 146 flying testbed will have one of its four turbofans replaced by a VOLISAN 2 MW (2,700 hp) electric motor, adapted by SAAB powered by its AE2100 turboshaft, controlled and integrated by Aero with a 2 t (4,400 lb) battery developed by ESKI. The first flight of the MRJ was in November 2019.

Development

Announced on 28 November 2015 at the Royal Aeronautical Society in Ampuria, the Aero 146E is schedule to fly in 2019. It will anticipate a safe, efficient, and cost-effective hybrid single-aisle airliner. Aero and VOLISAN have collaborated since April 2014 on the E-Aircraft Systems House for electric propulsion components, including ground tests. It will help establish certification requirements for electric aircraft.

Testing

The maiden flight of the Aero 146E took place on 14 November 2019.

Design

An Aero 146 flying testbed will have one of its four turbofans replaced by a 2 MW (2,700 hp) electric motor, with provisions to replace a second turbofan. Aero will build the control architecture and integrate the systems, SAAB will adapt the VOLISAN motor and the fan to the existing nacelle, bring the turboshaft, generator and power electronics and VOLISAN the electric motor and its power electronic control unit, the inverter, DC/DC converter and power distribution. High-power propulsion systems are challenged by thermal effects, electric thrust management, altitude and dynamic effects on electric systems and electromagnetic compatibility issues.

The electric machines should attain a 10-times-higher power-to-weight ratio. Pressurization, insulation and separation will avoid the corona effect: high altitude, high voltage arcing. Hybrid electric can offer improvements with present Battery Technologies : using them to boost power for takeoff and climb and electric-only descent would lower fuel burn per sector by double digits, and would reduce noise and local atmospheric emissions.

Customers

Orders

SAK Varkana was the first customer, with an order for 150 Aero 146Es and an option for 50 more. It is schedule to become the launch customer of the aircraft, with first deliveries scheduled for 2022.
