This solar powered drone can fly for 90 days and has self-healing code. See all amazing technical features

US tech company Skydweller Aero has partnered with French defense firm Thales to develop a new solar-powered drone for maritime surveillance. The aircraft is expected to stay in the air for up to 90 days.

Maritime Surveillance Drone

Skydweller Aero and Thales have announced their collaboration on a maritime surveillance drone. The drone is powered completely by solar energy and is designed to fly continuously without refueling. The first goal is to achieve a flight duration of 90 days.

The drone has been created for extended defense surveillance missions. Thales will provide radar systems tailored for maritime operations. This partnership aims to improve monitoring over long ocean routes.

Drone’s Technical Features

The drone collects energy from over 17,000 solar cells. These are spread across 2,900 square feet of wing area. The wingspan of the drone is 236 feet, which is 25 feet longer than a Boeing 747.

Under good conditions, these solar cells can generate up to 100 kilowatts of power. The drone's batteries store energy for night flight, although capacity loss over time could affect endurance.

The aircraft is made from carbon fiber and can carry 800 pounds of payload. This allows it to transport radar and other systems necessary for maritime patrol.

Focus on Mid-Altitude Performance

Many previous solar-powered aircraft have failed due to structural stress at mid-altitudes. These failures happened when aircraft climbed or descended through altitudes between 6,500 to 32,800 feet.

The Skydweller drone is designed to function within that same altitude range. It uses software to reduce turbulence-related stress. The gust-load alleviation system is built into its flight controls to avoid damage.

To stay airborne for 90 days, the drone must operate without failure. It is equipped with a quadruple-redundant flight control system. If one system fails, another takes over.

Its vehicle management system uses self-healing code. If any software string fails, it is shut down, fixed, and restored mid-flight. This ensures the drone remains operational at all times.

These technologies aim to prevent mission disruption and ensure full system recovery while in the air.

Limitations and Future Plans

While the drone can fly at night using stored solar energy, battery life will reduce over time. This limits the potential maximum patrol time. Also, because it relies on sunlight, it cannot be used in polar regions during winter.

Future test flights will assess the full capability of the drone. The team will focus on expanding the maximum duration and testing the radar integration.

Despite these limitations, the project marks progress in renewable energy and surveillance.

FAQs

What makes the Skydweller drone different from earlier solar aircraft?
Skydweller is built to fly at mid-altitudes safely, using gust-load control and self-healing systems for uninterrupted long-duration surveillance missions.

How will Skydweller manage flight at night or in low-light areas?
It uses charged onboard batteries to fly at night but avoids low-light zones like polar regions in winter to maintain energy levels.
