In 1917 Dr. Ing. Rudolf Wagner submitted a design for a steam powered "R-Flugzeug" to the "Inspektion
der Fliegertruppen" (Technical Service of the Imperial German Airforce). Wagner was already quite well
known for maritime developments, including light-weight steam turbine plants and proposed to used such
a propulsion for a large aircraft. The intended powerplant with 1000 hp would have been placed in the
fuselage would have powered large diameter contra-props, pilot and part of the crew would have been
placed in the upper cabin, bombload and the rest of the crew in the lower compartment.
No estimated data are known, span seems to have been around 40 m, similar to other then current "R-
Flugzeuge"
The reconstruction, using patent files and mentions in contemporary literature was done by Peter Garnatz and
Günter Kusch and published in Luftfahrt International N°24 1977.
