Airbus has acquired former Cello Aviation Avro RJ100 G-ILLR (msn E3379) for use as its E-Fan X demonstrator. Under the project, which is being undertaken in partnership with Rolls-Royce and Siemens, the RJ100’s number three engine will be replaced by a 2-megawatt electric-driven fan supplied by Siemens, fitted inside a standard 146/RJ engine pod. Rolls-Royce will provide an AE2100 engine driving a 2.5-megawatt generator, to be mounted in the rear cabin, and a battery sufficient to produce 2 megawatts of power for takeoff and cruise will be installed in the cargo holds. The modified 146 could fly in 2020. G-ILLR has been stored at Cranfield since Cello ceased operations in October.
