The Rumpler G.I was a bomber aircraft produced in Germany during World War I, together with refined versions known as the G.II and G.III.[1]
Design and development
[edit]Based on a prototype with the factory designation 4A15, the G.I and its successors were built to a conventional bomber design for their time, two-bay biplanes with unstaggered wings of unequal span.[2] The pilot sat in an open cockpit just forward of the wings, and open positions were provided in the nose and amidships for a gunner and observer. The engines were mounted pusher-fashion in nacelles atop the lower wings and enclosed in streamlined cowlings.[2] Fixed tricycle undercarriage was fitted, with dual wheels on each unit.[2]
The G.II version was almost identical, but featured more powerful engines and carried a second 7.92 mm (.312 in) machine gun and increased bombload.[2] The G.III was again similar, but had engine nacelles that were now mounted on short struts clear of the lower wing.[2]
