Rohrbach Metall-Flugzeugbau
Rohrbach Metall-Flugzeugbau was an airplane factory located in Berlin, Germany and founded in 1922 by Dr.-Ing Adolf Rohrbach. Rohrbach was a pioneer in building airplanes based on the metal stressed skin principle. At the time of the early aircraft production the Versailles Treaty forbade the construction and export of large aircraft in Germany, so Rohrbach set up a Danish company, the 'Rohrbach-Metall-Aeroplan Co. A/S', to build the early Rohrbach aircraft. The strict regulation of the aircraft industry was relaxed in 1926 allowing the Rohrbach series to be built at the Rohrbach Metall-Flugzeugbau GmbH factory in Berlin. The company enjoyed only limited commercial success, with the Rohrbach Roland ten-seat airliner as its only model built in any quantity. By 1934 the company was taken over by Weser Flugzeugbau, where Adolf Rohrbach became technical director.

Rohrbach Ro IV Inverness
The Rohrbach Ro IV, also known as the Beardmore BeRo.2 Inverness was an all-metal monoplane flying boat of the 1920s. Designed by the German company Rohrbach for the British Royal Air Force, two were ordered, one completed by Rohrbach's Danish subsidiary and the second by the British licensees, William Beardmore and Company, but the type performed poorly during testing and was abandoned. Design and development Dr.-Ing. Adolf Rohrbach, formerly of Zeppelin-Staaken, set up Rohrbach Metall-Flugzeugbau in 1922 to design and build large all-metal aircraft, with stressed skin structures, unusual for the time. In order to evade the restrictions of the Treaty of Versailles, Rohrbach set up a Danish subsidiary, Rohrbach Metal-Aeroplan Co A/S to assemble aircraft.Stroud ''Aeroplane Monthly'', January 1991, p. 51.

Rohrbach Ro XI Rostra
The Rohrbach Ro XI Rostra was a flying boat built in Germany in 1928 for use as a transatlantic mail plane. Design and development The Ro XI shared the same general configuration its predecessor, the Ro V Rocco: a conventional, high-wing flying boat with cruciform empennage and two engines mounted tractor-fashion in nacelles mounted on struts above the wing. The flight deck and cabin were fully enclosed. However, while the Rocco's wings had been braced by struts, the Rostra's wings were a fully cantilever design. The aircraft featured a set of masts and sails that could be deployed for extended travel on water in the event of a forced landing. By late 1928, Philadelphia journalist Mildred Johnson was organising an east-to-west transatlantic flight aboard the Rostra, initially with three other passengers, but later as the sole passenger. In middle of 1929, the Rostra made a preliminary round trip between Travemünde and Stockholm carrying ten passengers, and a longer-range flig ...

Rohrbach Ro X Romar
The Rohrbach Ro X Romar was a German long-range commercial flying-boat and the last aircraft designed and built by Rohrbach Metall Flugzeugbau GmbH. Development The Romar was the final production aircraft from Rohrbach and was a monoplane flying-boat with a crew of four or five and two cabins for a total of 12 passengers. The revised Romar II could accommodate 16 passengers. It had three BMW VIUZ Vee piston engines strut mounted above the wing. The first aircraft flew on 7 August 1928 and was unveiled at the Berlin Aviation Exhibition in October 1928. Only four aircraft were built, three were used on Baltic services by Deutsche Luft Hansa and one was supplied to the French Navy.

Rohrbach Ro IX Rofix
The Rohrbach Ro IX "Rofix" was a German all-metal monoplane fighter aircraft designed in February 1924 by Kurt Tank for Rohrbach. History The initial order for the aircraft was for two test aircraft, with a view of producing 50. Construction began in April 1926, and by the summer, the first prototype, with serial number 22, was complete. The prototype was tested in Denmark due to aircraft building restrictions on Germany at the time. However twice the prototype crashed, first in January 1927, and again 15 July 1927 killing the pilot Paul Bäumer. Despite good characteristics in flight and landing, some problems led to modifications. It was powered by a 600 hp BMW VI engine, and two synchronized rifle calibre machine guns in the fuselage. Two more guns in the wings were planned.

Rohrbach Ro VIII Roland
The Rohrbach Ro VIII Roland was an airliner produced in Germany during the 1920s. It was a conventional strut-braced, high-wing monoplane, based loosely on the Zeppelin-Staaken E-4/20 that Adolf Rohrbach designed in 1920. It had a fully enclosed flight deck and passenger cabin, and featured fixed, tailskid undercarriage. Power was supplied by three engines, one in the nose, and two mounted in nacelles on the wings. Construction was of metal throughout. Design and development In 1926 Deutsche Luft Hansa purchased the prototype Roland, followed by five production examples over that year and the next.Munson 1982, p.138 The production machines were built with open flight decks, although they were later enclosed, as on the prototype. These were put to work servicing a route between Berlin and London via Hanover and Amsterdam. In July 1927 the Roland held the world endurance record for a payload of 1,000 kg with a flight of 14 hours 23 minutes, and the world distance record for a ...

Rohrbach Ro VII Robbe
The Rohrbach Ro VII Robbe ( en, Seal) was an all-metal, twin engine flying boat built in Germany in the 1920s. It could be adapted to commercial or military rôles. Design and development As the full company name (Rohrbach Metall-Flugzeugbau) makes clear, all Rohrbach aircraft were all-metal, including their duralumin skinning. The Robbe was a monoplane with a high wing described at the time as a semi-cantilever structure, meaning that there were no rigid wing struts but that it retained external bracing with flying wires to the wings from the lower fuselage. The wings were mounted with 5° of dihedral. In plan they were straight tapered, with unswept leading edges and blunt tips. Internally the wings were built around single box spars, assisted by leading edge and trailing edge boxes. The edge boxes also served as fuel tanks. At this time there were still doubts about the repairability of metal aircraft, so the Robbe's two-part wing was designed to be easy to inspect internall ...

William Beardmore & Co
William Beardmore and Company was a British engineering and shipbuilding conglomerate based in Glasgow and the surrounding Clydeside area. It was active from 1886 to the mid-1930s and at its peak employed about 40,000 people. It was founded and owned by William Beardmore, later Lord Invernairn, after whom the Beardmore Glacier was named. History Forged steel castings, armour plate and naval guns The Parkhead Forge, in the east end of Glasgow, became the core of the company. It was established by Reoch Brothers & Co in 1837 and was later acquired by Robert Napier in 1841 to make forgings and iron plates for his new shipyard in Govan. Napier was given the contract to build , sister ship to the Royal Navy's first true ironclad warship, . Parkead was contracted to make the armour for her, but failed, so the manager, William Rigby called in William Beardmore Snr, who at the time was superintendent of the General Steam Navigation Company in Deptford, to help.

Beardmore Inflexible
The Beardmore Inflexible, also known as the Rohrbach Ro VI, was a three-engined all-metal prototype bomber aircraft built by William Beardmore and Company at Dalmuir, Scotland. Design and development William Beardmore and Company had acquired a licence for the use of the Rohrbach principle for stressed-skin construction. Using these principles and drawings supplied by Rohrbach for the RoVI, the Beardmore company built a massive all-metal three-engined transport, the ''Beardmore Inflexible''. The aircraft was built in sections at Dalmuir between 1925 and 1927 which were shipped by sea to Felixstowe and from there delivered by road to the Aeroplane & Armament Experimental Establishment (A&AEE) at Martlesham Heath Airfield where it first flew on 5 March 1928. It appeared at the Hendon RAF Display later in the year. The aircraft was structurally advanced for its time and had good flying qualities. It was also a very large aircraft for the time, having a wingspan of - around great ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |

Rohrbach Ro IIIa Rodra
The Rohrbach Ro III was a twin-engined, all-metal flying boat built in Germany in the mid-1920s. A development of the Ro II, it could be configured either as an airliner or a reconnaissance aircraft. It was developed into the similar but more powerful Ro IIIa Rodra (Ro + dr(ei) + a), intended only as a military reconnaissance/bomber. Four Ro IIIs were bought by Japan and two Rodras by Turkey. Design and development Dr.-Ing. Adolf Rohrbach gained his initial experience with light-alloy structures for aircraft with Zeppelin at Staaken but in 1922 he founded the Rohrbach Metall-Flugzeugbau GmbH in Berlin. At that time powered aircraft construction was banned in Germany by the Versailles Treaty, so he established a second factory in Copenhagen. His first completed design, the all-metal Rohrbach Ro II was built there, as was the Ro III but the Ro IIIa Rodra was built in Berlin after the Versailles conditions were relaxed in 1926. Completion and flight testing were nonetheless done i ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |
