World War I

The history of Junkers aircraft production begins with the Junkers J1. Research for this aircraft began in 1914 and was interrupted by the start of the First World War. The prototype aircraft was completed in 1915 after the outbreak of the war. This aircraft is significant in that it was the first airplane to utilize an all-metal fuselage design. Contemporary aircraft were built around wooden frames constructed in a rib-and-stringer fashion, reinforced with wires, and covered with a stretched fabric. The J1 was a semi-monocoque design, using steel ribs and sheeting that formed both the stringers and the skin. At the time aluminum was still fairly expensive, so the J1 was made of sheet steel. It was quite heavy as a result, which translated into poor climb and maneuverability, yet its clean monoplane layout had very low drag, and the J1 was one of the fastest planes of its day, reaching speeds of 170km/hr. 1914 (MCMXIV) was a common year starting on Thursday (see link for calendar). ... Ypres, 1917, in the vicinity of the Battle of Passchendaele. ... 1915 (MCMXV) was a common year starting on Friday (link will display the full calendar). ... Monocoque (French for single shell) or unibody is a construction technique that uses the external skin of an object to support some or most of the load on the structure. ... Aluminum is a soft and lightweight metal with a dull silvery appearance, due to a thin layer of oxidation that forms quickly when it is exposed to air. ... A monoplane is an aircraft with one main set of wing surfaces, in contrast to a biplane or triplane. ...


Following the J-1, a series of "J-designated" aircraft followed, each advancing the state of the art in terms of strength and weight, but no single design progressed much beyond the prototype stage in terms of production potential. The J2 was an extensively "cleaned up" J1, while the J3 was to replace the steel sheeting with corrugated duralumin. IDFLIEG, in charge of aircraft evaluation, was unconvinced of the monoplane layout of these designs, and ordered a biplane version as the J4. Junkers took this opportunity to produce the entire aircraft of corrugated duralumin (except for some fabric on the rear fuselage) in order to lower weight. The J4 became Junkers' first design to enter production, with orders totalling 283, of which about 184 were delivered to operational units. Confusingly, these were referred to as the J1 in service. fuck u Duralumin (also called duraluminum, duraluminium or dural) is the name of one of the earliest types of age-hardenable aluminium alloys. ...


Junkers continued to believe in the monoplane layout, and continued the J-series with a number of newer monoplane designs. One of the most successful was the J7, which was later stretched to form the two-seat J8. The J8 was the first cantilever monoplane design, and looked extremely "modern" when compared to contemporary wire-braced biplane designs. The J8 was put into limited production by Fokker as the J10, a small number of which saw service on the Eastern Front just before the war ended. Fokkers first airplane, the Spin (1910) Fokker was a Dutch aircraft manufacturer named after its founder, Anthony Fokker. ...


The corrugated duralumin wing and fuselage "skin" introduced in the J-series became a trademark of Junkers aircraft built in the 1920s and 30s. Development continued during the course of World War I, including a growing partnership with Fokker. Several Junkers designs were licensed to Fokker during this period. The visual similarity of Junkers and Fokker aircraft during the next decade is attributable to this early affiliation. The Great War ended with German Navy trials of model J11 which was an all metal floatplane prototype. “The Great War ” redirects here. ...


Interbellum

In the immediate post-war era, Junkers used their J8 layout as the basis for the F-13, first flown on 25 June 1919 and certified airworthy in July of the same year. This four passenger monoplane was the world's first all-metal airliner. Of note, in addition to significant European sales, some twenty-five of these airplanes were delivered to North American customers under the Junkers-Larsen affiliate and were used primarily as airmail planes.

Year 1919 (MCMXIX) was a common year starting on Wednesday (link will display the full calendar). ...


The Treaty of Versailles signed only days after the F-13 flew, initially forbade any aircraft construction in Germany for several months. After that span of time only the design of civilian aircraft was permitted to Germany. Junkers developed a series of progressively larger civil aircraft including the single engined G.24 and three engined G.31. Neither aircraft was a commercial success. With the expiration treaty restrictions in 1926, Junkers introduced the Junkers W33 and Junkers W34 series which did find significant commercial success via large production orders in passenger, freight hauling, and, somewhat later, military configurations. The W-33/W-34 series also set multiple aviation "firsts" including records for flight duration, flight distance, altitude, rocket assisted take-off and inflight refueling between 1926 and 1930. The Treaty of Versailles (1919) was the peace treaty which officially ended World War I between the Allied and Associated Powers and Germany. ... 1926 (MCMXXVI) was a common year starting on Friday (link will display the full calendar). ... 1930 (MCMXXX) was a common year starting on Wednesday (link is to a full 1930 calendar). ...


Junkers' produced a design study in 1924 for a visit to the United States. The study outlined a four engined 80 passenger seaplane, incorporating a forward canard wing as well as a main wing, both of which were fitted above twin catamaran hulls. Passenger seating was to be provided both in the main wing and the hull sections of the craft. This Junkers design, including a scale model, was intended to illustrate an aircraft capable of trans-Atlantic operations of 8 to 10 hours and was completely revolutionary for its day.


The basic principles outlined in this design were later introduced in the Junkers G.38, which was introduced and put into regular service by Lufthansa. At the time of its introduction, this four engined transport was the largest landplane in the world carrying thirty-four passengers and seven crew members. The G.38 sat some of its passengers in the wing area outboard of the fuselage, the front of which was covered with windows.

Financial troubles

Around 1931 the company suffered from a series of financial difficulties that led to the collapse of the group of companies. The existing shareholders pressured Hugo to leave the company. Hugo, however, was the patent holder on a wide variety of the technologies used in most of the existing Junkers designs, including many of their engines. A patent is a set of exclusive rights granted by a state to a patentee (the inventor or assignee) for a fixed period of time in exchange for the regulated, public disclosure of certain details of a device, method, process or composition of matter (substance) (known as an invention) which...


A plan was started to solve both problems by "buying out" Hugo's engine patent portfolio and placing it into the hands of a new company, the Junkers Motoren-Patentstelle GmbH, which was eventually formed in November 1932.[1] The new company would then license the technologies back to the various companies, most notably what was then Junkers Motorenbau (one of many "Jumo" companies). However, before Junkers actually transferred his patents to the Patentstelle, the collapse of the Junkers consortium was solved by the sale of the Junkers Thermo Technik GmbH to Robert Bosch who still uses the brand name to the present. Robert Bosch at the age of 27 Robert Bosch (September 23, 1861 - March 12, 1942), German industrialist and philanthropist, born in Albeck near Ulm as the 11th child of Servatius and Margarete Bosch, themselves children of wealthy farmers. ...


Nazi takeover

Unfortunately for Junkers, both the company and the man, the Nazi party came to power in Germany in 1933 and all German aviation development was shifted away from long-range civil aircraft types. Hugo Junkers himself was forced to transfer all his patents to the Nazis, who doubted that Junkers would comply with their plans. Shortly after, his holdings were expropriated and he was placed under house arrest. The company that had pioneered commercial aviation development for at least a decade was relegated to relatively small one- and two-engined military design competitions issued by the Reichsluftfahrtministerium (RLM) the "Reich Aviation Ministry". Two exceptions to this were the legendary Ju 52 and the Ju 90. The Nazi Party (German: , or NSDAP, English: National Socialist German Workers Party), was a far-right, racist political party in Germany between 1920 and 1945. ... 1933 (MCMXXXIII) was a common year starting on Sunday. ...

Ju 52 development had started in 1928 as a single-engined commercial transport and evolved, initially to a two-engined, later into the classic "trimotor" design for which the Tante Ju became world famous. The Ju 52 was a bona fide commercial success, with over 400 airplanes delivered to various airlines around the world prior to the outbreak of World War II, including the countries of: Finland, Sweden, Argentina, Brazil, Uruguay, Ecuador, Peru, Mexico, South Africa, Denmark, Norway, Italy, UK, Belgium, Hungary, Estonia, Greece, Spain, and of course, Germany. Amazingly, and in tribute to its rugged design, both Spain and France resumed Ju 52 production after cessation of the Second World War.

With the introduction of the Junkers Ju 86 bomber of 1934, Junkers abandoned the corrugated sheeting of his earlier designs. The basic layout was used in the four-engine Junkers Ju 89 heavy bomber, but this program ended with the death of Walter Weber, and his Ural bomber program along with him. Junkers then adapted the Ju 89 to passenger use, introducing the Junkers Ju 90, one of the first planes specifically designed for scheduled trans-Atlantic flights to the US. Developed in 1937, the aircraft suffered multiple setbacks with crashes of prototypes in 1937 and 1938. Further refinements enabled certification in 1939 and spurred South African Airways to make an initial order for two aircraft fitted with US-built Pratt & Whitney engines. Just as the aircraft was being readied for its first commercial flights, World War II began. With the outbreak of hostilities, all models were requisitioned by the Luftwaffe for military air transport roles, and later, long-range maritime patrol.

World War II

Military aircraft production was begun by the company in the 1930s and eventually monopolized all its resources. Perhaps the most notable design was the Junkers Ju 87 Stuka dive bomber, one of the Luftwaffe's most effective aerial weapons and continually used for bombing attacks as an integral part of the Blitzkrieg strategy. The Stuka was used for both precision tactical bombing and the strafing of enemy positions, acting as a sort of "airborne artillery" that was able to keep up with the fast-moving tanks and attack defended points long before traditional artillery could be brought into range. Later in the war it was fitted with a large cannon and employed in a "tank busting" role against Soviet armour. It gained much notoriety for its use at both Dunkirk and later Stalingrad, where it caused enormous destruction under Field Marshal Wolfram von Richthofen's VIII Air Corps.

Perhaps even more successful was the Junkers Ju 88, the primary light bomber of the German forces. It was used in practically every role imaginable; level bomber, shallow-angle dive bomber, night fighter and bomber destroyer and in anti-shipping raids. A variety of improved versions were also produced over the course of the war, including the Ju 188 and Ju 388 which included numerous features for better performance, but never replaced the Ju 88 outright. A much more formidable aircraft was also planned, the Junkers Ju 288, but the required high-power engines never worked and the effort was eventually abandoned.

A total of 4,845 Ju 52s were produced before and during the war. The wide availability of Ju 52s enabled their immediate utilization for the German war effort as a transport aircraft for delivering men and supplies. They were additionally used, with minor modification, to carry out bombing raids. Prior to WWII, the Ju 52 was utilized in the Spanish Civil War, where it took part in the Condor Legion's destructive raids on Durango and Guernica in 1937 which illustrated to the world - for the first time - the destructive potential and horror of strategic bombing. Unfortunately for its pilots and military passengers, by the outbreak of WWII, the Ju 52 was a thoroughly obsolete military design and unlike many other famous Luftwaffe aircraft, the Tante Ju was cumbersome, slow and therefore vulnerable to attack.

Junkers also ran an engine factory, and in 1923 they separated it from the parent to form its own company, Junkers Motoren, or Jumo. This company expanded greatly in the 1920s and 30s, with factories spread across Germany. Jumo was the first German company to offer a truly modern engine suitable for aviation in the form of the 650hp Jumo 210. But with the rapid advances in airframes, after a few short years this engine was considered to be underpowered causing Jumo to respond with the much larger Jumo 211. Perhaps unsurprisingly the 211 saw widespread use in Junkers bombers, but was little used otherwise, due largely to the better power output of the competing Daimler-Benz DB 601. Further development of the 211 led to the superb Jumo 213, which was in high demand for practically every late-war piston-engined aircraft. Their Jumo 004 jet engine was the first to be considered production quality and used in the then revolutionary Me 262 jet fighter. Jumo 210 The Jumo 210 was Junkers Motorens first production gasoline aircraft engine, produced just before the start of World War II. It produced about 650hp in common versions, and can be considered a counterpart of the Rolls-Royce Kestrel in many ways. ...

The Junkers company survived the Second World War and was reconstituted as Junkers GmbH and was eventually merged into the MBB consortium. Within West Germany, Junkers GmbH was engaged in research on the future of aerospace transportation during the fifties and early-1960s.
