New Airbus Project to Evaluate Wake Energy Retrieval Conops

The Airbus “fello’fly” project will evaluate the use of Wake Energy Retrieval (WER) flying, where a follower aircraft will retrieve the energy lost by the wake of a leader aircraft, by flying in the smooth updraft of air it creates. (Airbus)

Under new agreements signed with two airlines and several air navigation service providers (ANSPs), Airbus will evaluate the use of Wake Energy Retrieval (WER) to reduce aircraft emissions.

The company confirmed agreements with Frenchbee and SAS Scandinavian Airlines, as well as France’s Direction des Services de la Navigation Aérienne (DSNA), the UK’s NATS and Eurocontrol for their new “fello’fly” project in a Sept. 9 press release.

“WER replicates the behavior of birds, which fly together to reduce their energy consumption. The technique of a follower aircraft retrieving energy lost by a leader, by flying in the smooth updraft of air the wake creates, reduces fuel consumption in the range of 5-10 percent per trip,” Airbus said.

Flight testing will take place throughout 2020 using two Airbus A350 aircraft, with the involvement of the airlines and ANSPs as early as 2021 in an oceanic airspace.
