Advancing the US Quest for a Solar-Powered UAV with Uninterrupted Yearlong Flight Capability
PHASA-35: A Revolutionary Solar-Powered Drone Redefining Aerospace Technology
In the realm of aerospace innovation, the PHASA-35 project stands out as a remarkable endeavor that showcases the potential of solar-powered drones. Spearheaded by defense and aerospace giant BAE Systems, this project has garnered attention for its cutting-edge approach to aerial capabilities, backed by funding from the US Army’s Space and Missile Defense Command Technical Center.
At the heart of PHASA-35 lies its ingenious utilization of solar energy to power its flight. By harnessing the sun’s rays, the drone not only propels itself through the skies but also charges a compact battery pack during daylight hours. This stored energy enables the drone to continue its operations even through the night, granting it an impressive operational span that can extend up to a full year.
Measuring an expansive 35 meters in wingspan and weighing 150 kilograms, this solar electric aircraft boasts a carrying capacity of 15 kilograms. Crafted from advanced composite materials, the drone houses an innovative energy management system, photovoltaic cells, photovoltaic panels, and rechargeable batteries. While its flight speed may not be particularly swift, hovering around 0.3 meters per second, PHASA-35’s true prowess lies in its ability to cruise through the stratosphere. Shielded from the effects of rain, wind, and civilian aircraft, it offers an unwavering vantage point for extended periods.
The potential applications of PHASA-35 are as diverse as they are impactful. From intelligence gathering to military reconnaissance and search and rescue operations, this drone showcases its versatility across various sectors. Beyond its sensor capabilities, the drone can serve as a vital component of communication networks, providing coverage for 4G, 5G, and other data transmission methods during emergencies. It could play a pivotal role in border patrol initiatives and even replace conventional satellite systems in commercial settings.
A recent milestone in this groundbreaking project involved a 24-hour test flight conducted at the White Sands test site in New Mexico. BAE Systems achieved a remarkable feat by successfully maneuvering the solar-powered aircraft to an altitude of 20,000 meters within the stratosphere. This accomplishment not only underscores the drone’s capabilities but also highlights the progress achieved in its development.
Anticipating the future, BAE Systems has announced plans for the commercial availability of the PHASA-35 model by the mid-2020s. This move promises to revolutionize the aerospace landscape, offering a game-changing solution that blends sustainability with advanced technology. As the project continues to evolve, the world watches with anticipation to witness the transformative impact of PHASA-35 on the future of aerial operations.
