BMW IV
The BMW IV was a six-cylinder, water-cooled inline aircraft engine built in Germany in the 1920s. Power was in the 180 kW (250 hp) range. World record On 17 June 1919 Franz Zeno Diemer flew a DFW F37, powered by a BMW IV engine to an unofficial world record height of from Oberwiesenfeld, reaching that altitude in 89 minutes. Diemer stated at the time, "I could have gone much higher, but I didn't have enough oxygen."

Heinkel HD 39
The Heinkel HD 39 was a special-purpose cargo aircraft developed in Germany in the 1920s to distribute the Berlin newspaper '' B.Z.''. It was a conventional single-bay biplane with staggered wings of equal span, and a fuselage that nearly filled the interplane gap. The pilot sat in an open cockpit, and the undercarriage was of fixed, tailskid type with divided main units. The sole example of the type was built after Ernst Heinkel found out, by chance, that ''B.Z.'' required such an aircraft and had ordered two machines from Albatros. Heinkel convinced publisher Ullstein-Verlag to purchase a third aircraft from his firm. The design was based on the HD 27 mail plane, and had a specially-designed payload bay to carry newspapers in 50 kg (110 lb) bundles. 10 separate compartments in the bay could be individually opened in flight in order to air-drop newspapers in places where the HD 39 could not land. The HD 39 entered service alongside two Albatros L 72s in April 1926 ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |
Liberty L-6
The Liberty L-6 was a six-cylinder water-cooled inline aircraft engine developed in the United States during World War I. Design and development The Liberty L-6, which developed 200–215 hp, was built by the Thomas-Morse Aircraft Corp. and Wright Aeronautical Corp. Since it was based on the same engine design as the more successful Liberty L-12 V-12 liquid-cooled aviation engine, the L-6's resemblance to the Mercedes D.III German aviation engine, the source for the Liberty V-12's own cylinder and valvetrain design, resulted in the American L-6 engine design bearing a close visual resemblance to the German straight-six aviation powerplant in a number of respects, with at least one L-6 even being mounted postwar into a captured Fokker D.VII fighter for testing in the US. The Liberty L-6's smaller displacement of some 825 cu. in. (13.5 liters) versus the late-war German Mercedes D.IIIaü's 903 cubic inches (14.8 liters) do not seem to have handicapped the American straig ...

Type 95 Heavy Tank
The Type 95 heavy tank was the final result of Japanese multi-turreted tank design, and was in commission during the time period between World War I and World War II. Modeled on German and Italian tank designs, this tank featured 3 turrets. The main armament being a 70 mm cannon in a central turret, with its secondary front turret mounting a 37 mm gun and a 6.5 mm machine gun in the rear turret. Four prototypes were produced in 1934. History After World War I, major powers around the world quickly adopted the revolutionary design of French Renault FT light tank. One of the most successful features on the Renault FT was a 360 degree rotating turret. While developing new single-turreted tanks more closely based on the Renault FT, many countries, including Japan, also experimented with the possibility of multi-turreted designs. Design Forerunner Type 91 heavy tank The Imperial Japanese Army made the decision to develop heavy combat vehicles, which was prompted ...

Rohrbach 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 ...

Airco DH
The Aircraft Manufacturing Company Limited (Airco) was an early United Kingdom, British aircraft manufacturer. Established during 1912, it grew rapidly during the First World War, referring to itself as the largest aircraft company in the world by 1918. Airco produced many thousands of aircraft for both the British and Allied military air wings throughout the war, including fighter aircraft, fighters, trainer aircraft, trainers and medium bomber, bombers. The majority of the company's aircraft were designed in-house by Airco's chief designer Geoffrey de Havilland. Airco established the first airline in the United Kingdom, Aircraft Transport and Travel Limited, which operated as a subsidiary of Airco. On 25 August 1919, it commenced the world's first regular daily international service. Following the end of the war, the company's fortunes rapidly turned sour. The interwar period was unfavourable for aircraft manufacturers largely due to a glut of surplus aircraft from the war ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |
LFG V 60
The LFG V 60 was a small, single engine, tandem seat floatplane training aircraft, designed and built in Germany in the mid-1920s. About five were constructed. Design and development The LFG V 60 was a biplane floatplane, with wings of constant chord and with rounded wing tips; they were of approximately equal span and mounted with little stagger. It was a two bay biplane with pairs of parallel interplane struts, though the inner bay was quite narrow. There were ailerons on both upper and lower planes, externally connected. Its engine was a six cylinder inline, water cooled BMW IV, mounted with its cylinder heads exposed, which drove a two blade propeller. The fuselage was flat sided and accommodated the two crew in a continuous open, tandem cockpit. The tailplane was mounted on top of the fuselage and the vertical tail was tall and rounded, the rudder A rudder is a primary control surface used to steer a ship, boat, submarine, hovercraft, aircraft, or other vehicl ...

LFG V 59
The LFG V 59 and the LFG V 61 were single engine, twin float passenger seaplanes designed and built in Germany in 1926 by the Luft-Fahrzeug-Gesellschaft. They differed only in their engines. Design and development The V 59 and V 61 were both twin float seaplanes, essentially identical apart from their engines and designed to carry four or five passengers. The V 59 was powered by a BMW IV 6-cylinder water cooled inline and the V 61 by a much more powerful, Bristol Jupiter 9-cylinder radial. They were metal aircraft both in frame and covering, low wing monoplanes of the semi-cantilever kind with external bracing between the upper fuselage and wing and further support from below via the flat topped floats. The wings were straight tapered with rounded tips. The fuselage was flat sided and bottomed, with windows down the side and with a braced tailplane mounted on top of it. The rudder extended well below the keel. Operational history Both the V 59 and ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |
