The Zeppelin-Staaken R.V was one of a series of large bombers called Riesenflugzeugen, intended to be less vulnerable than the rigid airships in use at the time.

Bomber Military aircraft for attack of ground targets with bombs or other heavy ordnance

A bomber is a combat aircraft designed to attack ground and naval targets by dropping air-to-ground weaponry, firing torpedoes and bullets, or deploying air-launched cruise missiles.

Riesenflugzeug

A Riesenflugzeug, sometimes colloquially referred to in English as an R-plane, was a large World War I German bomber, possessing at least three aircraft engines, more usually being powered by four or more engines, sometimes of more than one make, model or power level. These were large multi-engine aircraft capable of flying several hours with larger bomb loads than the smaller Grossflugzeug bombers such as the Gotha G.V. Some of the earliest Riesenflugzeuge were given G-type designations before being redesignated, but a major distinction was that the requirements for the R-type specified that the engines had to be serviceable in flight. As a result, designs fell into two groups - those with the engines mounted centrally inside the fuselage using gearboxes and driveshafts to transfer the power to propellers mounted between the wings, and those with conventional powerplant installations mounted in large nacelles or the nose of the aircraft where engineers would be stationed for each group of engines. The transmission of power from the centrally mounted engines to the remote, most often wing-mounted propellers proved troublesome in practice and most operational examples of Riesenflugzeug-class aircraft were of the second type, as with the all-direct-drive Zeppelin-Staaken R.VI.

Development

In 1916, Zeppelin moved development of large bombers to Staaken, Germany. The R.V was co-developed alongside the R.VI and R.VII. The R.V had two engine pods, each with two engines paired in tandem, driving single propellers through clutches, gearboxes and shafts. An additional tractor engine was also fitted in the nose of the fuselage. The pods were large enough for some inflight maintenance. The Model R.IV was selected for production, rather than the R.V, because the geared and clutched engines posed a higher developmental risk. Each R-series aircraft required a ground-crew of 50.

Staaken  is a locality at the western rim of Berlin within the borough of Spandau.

Zeppelin-Staaken R.VI

The Zeppelin-Staaken R.VI was a four-engined German biplane strategic bomber of World War I, and the only Riesenflugzeug design built in any quantity.

The Zeppelin-Staaken R.VII was six-engined large bomber - a Riesenflugzeug - of Imperial Germany, intended to be less vulnerable than the airships in use at the time.

Operational history

The sole R.V (R.V 13/15) was accepted into service with Rfa 501 (Riesenflugzeug Abteilung 501) on 23 December 1917, after a protracted development period, due to teething troubles with the engine transmission systems. After an initial operational mission on 25 January 1918, fifteen further operational missions were flown in eight months of service, before an emergency landing in fog ended its career on 18 October 1918.

General characteristics

Maybach Mb.IVa I-6 piston aircraft engine

The Maybach Mb.IVa was a water-cooled aircraft and airship straight-six engine developed in Germany during World War I by Maybach-Motorenbau GmbH, a subsidiary of Zeppelin. It was one of the world's first series-produced engines designed specifically for high-altitude use. It was quite different engine design than the previous Maybach Mb.IV, not just a simple modification.

The Siemens-Schuckert Forssman was a prototype bomber aircraft designed and built in Germany in 1914 and 1915. When its performance proved inadequate for its intended role, even after numerous modifications, the German Inspectorate of Flying Troops eventually accepted it into service as a trainer. Shortly after its acceptance into military service, the aircraft's fuselage fractured while on the ground, ending its career.

Siemens-Schuckert R.II

The Siemens-Schuckert R.II was a prototype bomber aircraft built in Germany during World War I. It was one of six aircraft based on the Siemens-Schuckert R.I that were originally intended to be identical, but which each developed in a different direction and were designated as different aircraft types by the German Inspectorate of Flying Troops. Although the R.II was the first of the batch to be completed, it was the last accepted into military service, and then only as a trainer.

The Siemens-Schuckert R.IV was a bomber aircraft built in Germany during World War I. It was one of six aircraft based on the Siemens-Schuckert R.I that were originally intended to be identical, but which each developed in a different direction and were designated as different aircraft types by the German Inspectorate of Flying Troops. The Maybach HS engines specified by the Idflieg proved unreliable, but with these engines were replaced by Benz Bz.IV engines, the R.IV saw service on the Eastern Front before being relegated to training duties.

It was one of six aircraft based on the Siemens-Schuckert R.I that were originally intended to be identical, but which each developed in a different direction and were designated as different aircraft types by the German Inspectorate of Flying Troops. Development of the R.V benefited from the experience that Siemens-Schuckert and the Idflieg had gained with the R.II, R.III, and R.IV, particularly in its choice of powerplants, where the R.V was spared from the troublesome Maybach HS engine. Between September 1916 and February 1917, the aircraft saw service on the Eastern Front before it was damaged in an accident and dismantled for spare parts.
