Linke-Hofmann R.II

02/28/2011. Of the firms that designed and constructed large, multi-engined Riesenflugzeuge (giant aircraft) during WW I, those created by the Abteilung Flugzeugbau (aircraft section) of the railway stock producer Linke-Hofmann-Werke Breslauer Aktiengesellschaft für Eisenbahnwagen-, Lokomotiv- und Maschinenbau at Breslau, Germany (now Wroclaw, Poland) attracted special attention, not only by their size, but also by the non-stereotype design.

The R.II was designed and constructed under the direction of chief engineer Paul Stumpf, who was formerly chief engineer to the Allgemeine Elektricitäts Gesellschaft (A.E.G.). The chief feature was a single large tractor airscrew turning at only 545 rpm, driven through a central drive by four 260 hp Mercedes engines placed in the fuselage. The 22 ft 7.65 in (6.90 m) Garuda propeller was the largest ever to fly.

In 1917 the Idflieg (Inspektion der Fliegertruppen, Inspectorate of Flying Troops) ordered two examples (s/n 55/17, 56/17) for delivery in July 1918, however, the first was not flown until January 1919. Intended as a bomber, the aircraft was flown as a twelve-passenger aircraft operated by a crew of six. The biplane with wings of unequal span proved to be very stable, could be flown with one hand and even with only two engines running the aircraft flew well.
