According to foreign media reports, the persistent high-altitude solar aircraft (PHASA-35) built by BAE Systems subsidiary Prismatic conducted the first fully integrated flight test over the Woomera test range of the Royal Australian Air Force (RAAF). The aircraft supported by the British Defense Science and Technology Laboratory (DSTL) and the Australian Defense Science and Technology Group (DSTG) is a high-altitude long-endurance (HALE) aircraft designed to fill the gap between aircraft and satellites.
According to BAE Systems, it completed the work from design to first test flight within 20 months, and built two full-size prototypes in 2019.
Compared with satellites, PHASA-35 is cheaper to build and operate, and it is also a durable, stable aerial platform with military and civilian applications including surveillance, communications, security, remote sensing, environmental science, forest fire detection, and maritime surveillance.

It is understood that the PHASA-35 has a wingspan of 35 meters, uses a dedicated carbon composite monolithic bearing structure, and weighs 150 kg. Thanks to the gallium arsenide solar cell array and lithium-ion battery system, the aircraft can continue to fly in the air for up to one year time. In addition, PHASA-35 can fly to an altitude of 70,000 feet (21,000 meters), achieve a flight speed of 50-78 knots (93km / h-145km / h), and can fly upwind.
Ian Muldowney, Director of Engineering at BAE Systems, said: "This is an outstanding early result, and it shows that we can make such rapid progress when we bring together the best people in the UK. It took less than two years to complete The design-to-flight work shows that we are able to meet the challenge set by the British government for the industry to deliver a future combat air system within the next 10 years. "
It is reported that BAE Systems plans to launch more flight tests in 2020.
