What is it about?
Airships, once common in early aviation, are being re-examined as a clean and efficient way to move goods. This study explores how large, rigid airships could be designed more accurately by updating century-old weight estimation methods using modern computational tools and historical data. The new framework predicts how much different parts of a rigid airship would weigh and helps guide future design studies. The research also compared the environmental impact of a historical U.S. Navy airship with today’s aircraft, ships, and trucks. Results show that a modernized airship could cut carbon emissions by 35 % to 84 % compared with conventional airplanes, while delivering goods faster than ships and more sustainably than trucks. The work highlights how improving old design methods with new analysis can help make future transportation greener and more efficient.

Why is it important?
Cargo transport faces a major challenge: meeting growing demand while cutting greenhouse gas emissions. This research is timely because it revisits a proven but overlooked technology—rigid airships—using modern design tools and sustainability goals. Unlike most studies that focus on airplanes or hybrid blimps, this work establishes one of the first modern frameworks for designing large rigid airships. By blending historical data with current engineering methods, it shows that airships could become a viable, low-carbon option for moving heavy goods to remote areas. The findings also help fill a century-long research gap in airship design and demonstrate that improving old engineering concepts with today’s tools can directly contribute to cleaner global logistics
Perspectives
This paper grew from my curiosity about whether historic airship designs could meet today’s sustainability needs, and from the realization that modern researchers rarely explore the design and engineering of rigid airships that once proved successful in cargo and passenger transport. I hope readers see that innovation does not always mean starting from scratch—sometimes it means rediscovering and improving what once worked well. I also hope this study encourages young engineers to look at past technologies through a modern lens and to explore creative, data-driven ways to make aviation more sustainable.
