UAVOS Successfully Completes Next ApusDuo Solar HAPS Test Flight

UAVOS announced another successful test flight of the ApusDuo solar-powered high-altitude platform system (HAPS) that took place at one of the Flight Centers in Europe. The test flight was conducted continuously for 11 hours, reaching altitudes of 15,000 meters. The ApusDuo successfully achieved more than two dozen test points, including energy balance validation, power and propulsion performance, and propellers RPM (Revolutions per minute) evaluation. The team also tested aircraft motor control efficiency which has had a number of refinements.

After operations in Europe, UAVOS plans to transport ApusDuo to Argentina and is accelerating preparations to perform the next phase of test flights in the stratosphere.   

“This was our consecutive successful test flight in which ApusDuo flew steadily across greater turbulence at higher altitudes. We achieved important program objectives and demonstrated UAVOS’s unique solar HAPS capabilities and experience. We’ll carefully verify the data from this test and move forward with
preparations to conduct the next stage of stratospheric flight tests,” –  commented Aliaksei Stratsilatau, CEO at UAVOS.

ApusDuo is a stratospheric UAV running on solar power, and is meant to provide persistent local satellite-like services. Built with carbon fibre composites, it can be landed, re-equipped with multitask payloads and re-deployed. It is also capable of flying autonomously from takeoff to landing and can be remotely operated from its ground control station.
