Airbus completes latest flight tests of high-altitude Zephyr UAS

Airbus Zephyr flight tests

Airbus has completed a new test flight campaign for its Zephyr High Altitude Platform Station (HAPS) in Arizona in the US.

The 2020 flight campaign focused on aircraft agility, control and operations to build upon previous campaigns, which Airbus said have proven the day and night stratospheric persistence of the unmanned aerial system (UAS) essential in commercial markets. 

This year’s campaign, held during the first three weeks of November, aimed to demonstrate operational flexibility and aircraft agility, particularly testing lower altitude flying and early stage transition to the stratosphere.

It also allowed the validation of a new flight planning tool suite and the development of operational concepts through multiple, varied flights in short succession.

“Having proven stratospheric flight, we continue to further mature the operational system with the objective to be more flexible and robust in order to meet our customer needs,” said Jana Rosenmann, Head of Unmanned Aerial Systems at Airbus.

“The outcome of this campaign is a valuable contribution to the full flight programme next year.”

The campaign team used a Zephyr aircraft, fitted with new software control systems and specific flight test instruments, plus associated lighter test aircraft to conduct multiple successful test flights during November. 

The flights demonstrated take-off, climb, cruise, upgraded flight control and descent phases, followed by successful landings. The objectives of the test campaign were all achieved showcasing a more resilient and capable aircraft.

Zephyr is a solar–electric, stratospheric UAS. It runs exclusively on solar power, above the weather and conventional air traffic, designed to fill a capability gap complementary to satellites, UAVs and manned aircraft to provide persistent local satellite-like services.

With the conclusion of this year’s successful test flight campaign, Zephyr has come another step closer to an operational reality, Airbus said in a statement.

“Zephyr will provide the potential to revolutionise disaster management, including monitoring the spread of wildfires or oil spills,” Airbus said. “It provides persistent surveillance, tracing the world’s changing environmental landscape and will be able to provide communications to the most unconnected parts of the world.”

In July 2018, the Zephyr team conducted a test flight campaign when Zephyr S flew in the stratosphere for nearly 26 days. It remains the longest flight duration of an aircraft ever made without refuelling.

The aircraft persisted in the stratosphere day and night, consistently achieved a dawn altitude of 60,000ft as well as its highest altitude of 71,140ft.
