According to NASM: During World War II, Bruno Nagler designed this sole prototype as a backpack portable helicopter. Although intended for sport or commercial courier duties, the German Air Ministry funded the project for military purposes with specifications for one-hour endurance and a 50-km (31-mile) operational radius. The blade-mounted engines proved unreliable because the tremendous centrifugal forces of rotation interfered with carburation. The NR 54 V2 underwent ground testing at the end of the war, but it never flew. It is on display at the Smithsonian Institution's National Air and Space Museum (NASM) Steven F. Udvar-Hazy Center in Chantilly, Virginia. The photo was taken on Sept. 1, 2025, by Mike Hirschberg. CC BY-SA 4.0
