Problem
Current long‑range aviation relies on fossil fuels, leading to high emissions and limited endurance for missions that require continuous, high‑altitude flight. Existing solar‑powered aircraft have not demonstrated the capability to sustain nonstop global circumnavigation, leaving a gap in proven, sustainable long‑duration air travel.
Solution
Halos is engineering a solar‑powered aircraft that uses NASA’s Prandtl Wing technology to achieve continuous, high‑altitude flight without refueling. The design integrates ultra‑lightweight composite structures with high‑efficiency photovoltaic cells to harvest solar energy during daylight and store it in advanced battery systems for night operation. By optimizing aerodynamic efficiency and energy management, the aircraft aims to maintain nonstop flight around the globe, showcasing the feasibility of solar energy for long‑range commercial and research missions. Successful demonstration would provide a platform for emissions‑free cargo transport, atmospheric data collection, and other high‑altitude applications.
Target Audience
Primary customers include aerospace operators seeking zero‑emission long‑range transport solutions and research organizations requiring persistent high‑altitude platforms for atmospheric or remote‑sensing missions.
