Skydweller drone achieves historic 90-day flight milestone

Aerospace experts have revealed a groundbreaking solar-powered drone capable of flying for 90 days.

Solar-powered Skydweller aircraft achieves remarkable 90 days of continuous flight

The Skydweller, a solar-powered surveillance drone created by Skydweller Aero and Thales, can remain airborne for up to 90 days without needing to land. Designed with carbon fiber and featuring a wingspan of 236 feet, it harnesses energy from over 17,000 solar cells. This allows it to fly continuously in ideal conditions, outperforming previous records held by aircraft such as the British jet Zephyr, which flew for 67 days. The drone operates at altitudes between 24,600 and 34,400 feet, reducing altitude at night to conserve power, and utilizes batteries for nighttime flying. It has advanced systems in place to manage potential mid-air failures and turbulence, making it a promising innovation in drone technology.

The Skydweller's extended flight capability marks a significant advancement in drone technology. This could redefine surveillance operations, particularly in maritime contexts, where continuous monitoring is essential. However, the reliance on solar energy and batteries raises questions about operational reliability during adverse weather conditions. The potential for failures in mid-air remains a concern as seen in other lightweight drones, making the design of the Skydweller crucial for its success.
