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. The Aquila first flew on 28 June 2016 with a second aircraft successfully flying in 2017. Internal development of the Aquila aircraft was stopped in June 2018.

Development

Aquila was developed by Facebook's Connectivity Lab. [3] The prototype airframe design and construction was led by Ascenta, a Somerset, England-based company acquired by Facebook in 2014. [1] Several scale models of the Aquila were built and flown to prove the concept prior to the full-scale prototype being built. [3]

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. [1] The 96-minute flight was considered successful. However, during landing, the aircraft touched down short of the intended landing zone and was damaged; [1] [4] the National Transportation Safety Board conducted an investigation into the accident, [5] as the drone suffered a structural failure just before touching down. [4] The aircraft was designed such that a production version would be able to support continuous flight in the stratosphere for 90 days. [6]

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. [7] 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. [8] The same month, it was announced that Aquila would be displayed at the Victoria and Albert Museum's spring "The Future Starts here" exhibition in 2018. [9]

In June 2018, as aerospace manufacturers start designing and building HAPS, Facebook decided to stop its program to work with partners like Airbus on HAPS connectivity and their technologies like flight control and high-density batteries. [2] In 2018, it was reported that Facebook and Airbus have scheduled test flights in Australia using the latter's Zephyr drone technology. [10] Zephyr share the same blueprint with Aquila as it also uses solar power. [10]

Design

The drone has a wingspan roughly the same as a Boeing 737, [1] but weighs only 880 pounds (400 kg). [3] 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. [1] Aquila is claimed to use the same amount of power as three blow dryers. [7] 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; [3] landings would take place on grassy surfaces. [1]

Aquila is intended to fly at altitudes of up to 90,000 feet (27,000 m) during the day, [1] 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; [3] 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. [8] The technology, which used high-bandwidth lasers to beam the Internet to remote locations, [11] was intended to provide access to 4 billion users, particularly in sub-Saharan Africa. [12]

The company is the US military's top supplier of small drones —notably the Raven, Switchblade, Wasp and Puma models.

<span class="mw-page-title-main">History of unmanned aerial vehicles</span>

Unmanned Aerial Vehicles (UAVs) include both autonomous drones and remotely piloted vehicles (RPVs). A UAV is capable of controlled, sustained level flight and is powered by a jet, reciprocating, or electric engine. In the twenty-first century, technology reached a point of sophistication that the UAV is now being given a greatly expanded role in many areas of aviation.

An electric aircraft is an aircraft powered by electricity. Electric aircraft are seen as a way to reduce the environmental effects of aviation, providing zero emissions and quieter flights. Electricity may be supplied by a variety of methods, the most common being batteries. Most have electric motors driving propellers or turbines.

A hydrogen-powered aircraft is an aeroplane that uses hydrogen fuel as a power source. Hydrogen can either be burned in a jet engine or another kind of internal combustion engine, or can be used to power a fuel cell to generate electricity to power an electric propulsor. It cannot be stored in a traditional wet wing, and hydrogen tanks have to be housed in the fuselage or be supported by the wing.

<span class="mw-page-title-main">Flight endurance record</span> Length of time an aircraft of a particular category spent in flight without landing

The flight endurance record is the longest amount of time an aircraft of a particular category spent in flight without landing. It can be a solo event, or multiple people can take turns piloting the aircraft, as long as all pilots remain in the aircraft. The limit initially was the amount of fuel that could be stored for the flight, but aerial refueling extended that parameter. Due to safety concerns, the Fédération Aéronautique Internationale (FAI) no longer recognizes new records for the duration of crewed airplane or glider flights and has never recognized any duration records for helicopters.

Urban Air Mobility (UAM) is the use of small, highly automated aircraft to carry passengers or cargo at lower altitudes in urban and suburban areas which have been developed in response to traffic congestion. It usually refers to existing and emerging technologies such as traditional helicopters, vertical-takeoff-and-landing aircraft (VTOL), electrically propelled, vertical-takeoff-and-landing aircraft (eVTOL), and unmanned aerial vehicles (UAVs). These aircraft are characterized by the use of multiple electric-powered rotors or fans for lift and propulsion, along with fly-by-wire systems to control them. Inventors have explored urban air mobility concepts since the early days of powered flight. However, advances in materials, computerized flight controls, batteries and electric motors improved innovation and designs beginning in the late 2010s. Most UAM proponents envision that the aircraft will be owned and operated by professional operators, as with taxis, rather than by private individuals.
