Airbus’ fello’fly project aims to demonstrate the technical, operational and commercial viability of two aircraft flying together for long-haul flights.
Through fello’fly, 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. This provides lift to the follower aircraft allowing it to decrease engine thrust and therefore reduce fuel consumption in the range of 5-10% per trip.
The technical solution that Airbus is working on involves pilot assistance functions necessary to ensure the aircraft they are flying remains safely positioned in the updraft of air of the aircraft they are following, maintaining the same distance, at a steady altitude.
In terms of the operational solution, Airbus is working, in collaboration with airlines and Air Traffic Control (ATC) providers, to identify the operational needs and suitable solutions for planning and executing fello’fly operations. This highlights the importance Airbus places on driving industry-wide activities to achieve emissions reductions targets defined by the International Civil Aviation Organisation (ICAO) and the Committee on Aviation Environmental Protection (CAEP).
Airbus is due to commence flight tests with two of its A350 aircraft in 2020. Given the high potential for a positive environmental impact for the industry, Airbus is targeting an ambitious timeline for a controlled Entry-Into-Service (EIS), which is expected before the middle of the next decade.
This new demonstrator project for optimized aircraft operation, strengthens Airbus’ position in a field where it is already heavily investing and focusing its research efforts on developing, innovating and leveraging emerging technologies, directly contributing to the sustainable offset of emissions reducing the environmental footprint of the aviation industry as a whole.
