Fly Like a Bird

Multinational aerospace corporation Airbus is investigating a new way for airliners to save fuel: by flying in formation, like a herd of migrating geese.

The manufacturers research incubator Airbus UpNext studied the aerodynamic efficiencies that arise out of flying in formation, CNN reports.

UpNext is planning to test the idea with two passenger jets as part of a demonstration project called fellofly. Early tests, involving two of the companys A350aircraft, already started in March 2020.

Its very, very different from what the military would call formation flight, Sandra Bour Schaeffer, CEO of Airbus UpNext, told CNN. Its really nothing to do with close formation.

By flying nearby each other, each bird or airplane benefits from the next objects wake. The tip of each birds wings creates a vortex, which can provide lift for the next bird behind it.

[The pilots] will be 1 1/2 to 2 nautical miles away from the leading aircraft, and slightly offset, which means they are on the side of the vortex, explained Bour Schaeffer, an experienced flight-test engineer, to CNN. Its no longer the vortex, its the smooth current of rotating air which is next to the vortex, and we use the updraft of this air.

According to Schaeffer, A350s could save anywhere between five and ten percent in fuel an enormous number.

Despite the fuel savings, having airliners fly closeby each other involves at least some level of risk. Before the technique could become mainstream, the team would have to convince service providers and government aviation agencies to change regulations to allow for airliners flying in formation.
