The Hansa-Brandenburg W.20 was a German submarine-launched reconnaissance flying boat of the World War I era, designed and built by Hansa-Brandenburg.[1]
Design and development
Due to the need to be stored and launched from a submarine aircraft carrier, the W.20 was a small single-seat biplane flying boat that was designed to be assembled and dismantled quickly.[1] It had a slender hull on which was mounted a biplane wing and a conventional braced tailplane.[1] It was powered by a seven-cylinder, 80 PS Oberursel U.0 rotary engine — basically a German-made near-clone of the Gnome Lambda pre-war French rotary — mounted on struts between the wings driving a pusher propeller.[1] The pilot had an open cockpit just forward of the lower wing.[1] Because of the slender hull stabilising floats were fitted below and at the end of the lower wings.[1] The submarine intended to carry the W.20 was not built and only three W.20s were built.[1]
