The Facebook Aquila is an experimental solar-powered drone developed by Facebook for use as an atmospheric satellite, intended to act as relay stations for providing internet access to remote areas.

Design and development

Aquila was developed by Facebook's Connectivity Lab[1] and the prototype was constructed by Ascenta, a Somerset, England-based company acquired by Facebook in 2014.[2] The drone has a wingspan roughly the same as a Boeing 737,[2] but weighs only 880 pounds (400 kg).[1] Aquila is of flying wing configuration, the upper surface of the wing being covered in solar cells to power the aircraft's four electric motors; batteries, composing half the aircraft's weight, provide power storage for night flight.[2] Aquila is claimed to use the same amount of power as three blow dryers.[3] While the prototype used a launch trolley to become airborne, production Aquilas are intended to be launched using helium balloons, carrying the aircraft to their operational height and releasing them;[1] landings would take place on grassy surfaces.[2]

Aquila is intended to fly at altitudes of up to 90,000 feet (27,000 m) during the day,[2] dropping to 60,000 feet (18,000 m) at night, with an endurance of up to three months, providing Internet service to a 50 miles (80 km)-radius area below its flight path;[1] if communications spectrum was assigned for the project, it would allow the 66% of Earth's surface that has poor or no internet access to be connected.[4]

In November 2017, a partnership with Airbus was announced to further development of the Aquila and the "high altitude platform station broadband connectivity system" (HAPS) project.[4]

Operational history

Scale models of the Aquila were built and flown to prove the concept prior to the prototype being built.[1] Following construction at Ascenta's factory in Bridgwater, England, the Aquila prototype was disassembled and shipped to Arizona, where it was first flown on 28 June 2016.[2] The 96-minute flight was considered successful, however in landing the aircraft touched down short of the runway and was damaged;[2][5] the National Transportation Safety Board conducted an investigation into the accident,[6] as the drone suffered a structural failure just before touching down.[5]

Following the crash, the prototype Aquila was modified with spoilers, provision for feathering the propellers, and refinement of the exterior surface of the aircraft; the second flight took place on 22 May 2017, with the one-hour, 46-minute flight being considered successful.[3]

In November 2017, it was announced that Aquila would be displayed at the Victoria and Albert Museum's spring "The Future Starts here" exhibition in 2018.[7]
