An Airbus plane flew a group of drones during a simulated autonomous refueling

Engineers from Airbus have demonstrated the ability to autonomously control a network of drones for...

refueling in the air. The system, installed on an A310 MRTT (Multi-Role Tanker) tanker aircraft, provided refueling guidance and drone flight control for six hours.

The test took place on March 21 over Cadizbay of the Atlantic Ocean off the coast of Spain. During the flight, engineers tested the Auto’Mate autonomous control system. During the test, an A310 MRTT aircraft flew four DT-25 drones, which simulated real-life aerial refueling.

During the six-hour flight, controlwas successfully transmitted from the ground station to the tanker by drones. The system used artificial intelligence and co-control algorithms to control the flight of four drones. During joint maneuvers, the devices approached the aircraft at a distance of up to 45 m and took up a position for refueling. 

During testing Auto’Matemonitored the aircraft's relative navigation, communicated between ships to enhance autonomy, and provided precise control to avoid collisions and other problems.

Air refueling is one of the keytechnologies that provide the ability to increase the duration of the drone mission indefinitely. However, transferring fuel from one aircraft to another with very different flight characteristics is a difficult task requiring a high degree of control precision.
