Heinkel He-51
The Heinkel He 51 was a German single-seat biplane which was produced in a number of different versions. It was initially developed as a fighter; a seaplane variant and a ground-attack version were also developed. It was a development of the earlier He 49. Design and development In 1931, Heinkel recruited the talented aircraft designers Walter and Siegfried Günter. Their first major design for Heinkel was the Heinkel He 49.Green and Swanborough 1994, p. 295. While this was officially an advanced trainer,Mondey 1996, p. 80. in fact it was a fighter. The first prototype, the He 49a, flew in November 1932, and was followed by two further prototypes, the He 49b, with a longer fuselage, and the He 49c, with a revised engine. The type was ordered into production for the still secret ''Luftwaffe'' as the He 51, the first pre-production aircraft flying in May 1933. Deliveries started in July of the next year. The He 51 was a conventional single-bay biplane, with all-metal co ... [...More Info...]       [...Related Items...]     OR:     [Wikipedia]   [Google]   [Baidu]   |

Biplane
A biplane is a fixed-wing aircraft with two main wings stacked one above the other. The first powered, controlled aeroplane to fly, the Wright Flyer, used a biplane wing arrangement, as did many aircraft in the early years of aviation. While a biplane wing structure has a structural advantage over a monoplane, it produces more drag than a monoplane wing. Improved structural techniques, better materials and higher speeds made the biplane configuration obsolete for most purposes by the late 1930s. Biplanes offer several advantages over conventional cantilever monoplane designs: they permit lighter wing structures, low wing loading and smaller span for a given wing area. However, interference between the airflow over each wing increases drag substantially, and biplanes generally need extensive bracing, which causes additional drag. Biplanes are distinguished from tandem wing arrangements, where the wings are placed forward and aft, instead of above and below. The term is also ...

Arado Ar 65
The Arado Ar 65 was the single-seat biplane fighter successor to the Ar 64. Both looked very similar. The only major difference was the use of a 12-cylinder inline engine versus the Ar 64's radial. The wingspan was also increased. The Ar 65 appeared in 1931 and six models were built. The first three 65a-c were prototypes, while the 65d-f were production models. The Ar 65d was delivered in 1933 and served alongside the Ar 64 in the two fighter groups - ''Fliegergruppe'' Döberitz and ''Fliegergruppe'' Damm. In 1935, the Ar 65 was reduced to a training aircraft. Production of the fighter was discontinued in 1936. However, the next year, 12 of them were presented to Germany's ally - the Royal Bulgarian Air Force. The final production total was 85 aircraft. Variants ;Ar 65a: Prototype, powered by a 559 kW (750 hp) BMW VI 7.3 12-cylinder water-cooled engine. First flight in 1931. ;Ar 65b: Prototype, similar to the 65a but with minor structural changes. ;Ar 65c: Prototyp ...

Polikarpov I-15
The Polikarpov I-15 (russian: И-15) was a Soviet biplane fighter aircraft of the 1930s. Nicknamed ''Chaika'' (''russian: Чайка'', "Seagull") because of its gulled upper wings,Gunston 1995, p. 299.Green and Swanborough 1979, p. 10. it was operated in large numbers by the Soviet Air Force, and together with the Polikarpov I-16 monoplane, was one of the standard fighters of the Spanish Republicans during the Spanish Civil War, where it was called Chato (snub-nose). Design and development The design for the 14th fighter for the VVS, the I-14, started as an advanced (for the era) monoplane under the direction of Andrei Tupolev. He grew concerned that the design would not mature, and ordered two backup biplane designs as the I-14A and B just to be safe. Polikarpov had just been released from prison in August 1932, and was handed the I-14A project. When both the I-14 and I-14A were ordered into production, Polikarpov's design, a development of the I-5 fighter became the famous ...

Soviet Union
The Soviet Union,. officially the Union of Soviet Socialist Republics. (USSR),. was a transcontinental country that spanned much of Eurasia from 1922 to 1991. A flagship communist state, it was nominally a federal union of fifteen national republics; in practice, both its government and its economy were highly centralized until its final years. It was a one-party state governed by the Communist Party of the Soviet Union, with the city of Moscow serving as its capital as well as that of its largest and most populous republic: the Russian SFSR. Other major cities included Leningrad (Russian SFSR), Kiev (Ukrainian SSR), Minsk ( Byelorussian SSR), Tashkent (Uzbek SSR), Alma-Ata (Kazakh SSR), and Novosibirsk (Russian SFSR). It was the largest country in the world, covering over and spanning eleven time zones. The country's roots lay in the October Revolution of 1917, when the Bolsheviks, under the leadership of Vladimir Lenin, overthrew the Russian Provisional Government ...

Condor Legion
The Condor Legion (german: Legion Condor) was a unit composed of military personnel from the air force and army of Nazi Germany, which served with the Nationalist faction during the Spanish Civil War of July 1936 to March 1939. The Condor Legion developed methods of strategic bombing that were shortly afterward used widely during the Second World War. The bombing of Guernica was the most infamous operation carried out by the Condor Legion. Hugo Sperrle commanded the unit's aircraft formations and Wilhelm Ritter von Thoma commanded the ground element. History of military aid to Spain After the military coup in Spain on 17 July 1936 started the Spanish Civil War, the Nationalists requested the support of Nazi Germany and Fascist Italy. The first request for German aircraft was made on 22 July, with an order for 10 transport aircraft. The German Führer Adolf Hitler decided to support the Nationalists on 25 or 26 July, but was wary of provoking a wider European war.Westwel ...

Potez 54
The Potez 540 was a French multi-role aircraft of the 1930s. Designed and built by Potez, it served with the French Air Force as a reconnaissance bomber, also serving with the Spanish Republican Air Force during the Spanish Civil War. Although obsolete as a bomber, it remained in service in support roles and in France's overseas colonies at the start of World War II. History This two-engine aircraft was built by the French Potez company to fulfill a 1932 specification for a new reconnaissance bomber. Built as a private venture, this aircraft, designated the Potez 54, flew for the first time on 14 November 1933. Designed by Louis Coroller, it was intended as a four-seat aircraft capable of performing duties such as bomber, transport and long-range reconnaissance. The Potez 54 was a high-wing monoplane, of mixed wood and metal covering over a steel tube frame. The prototype had twin fins and rudders, and was powered by two 515 kW (690 hp) Hispano-Suiza 12Xbrs V-12 engines ...

Nieuport Ni-52
The Nieuport-Delage NiD 52 was a French fighter aircraft of the 1920s. A single-engined sesquiplane, it served with the Spanish Air Force, being operated by both sides of the Spanish Civil War.Taylor and Alexander 1969, pp. 117-118. Development and design In 1924 Nieuport produced a design for a single-seat sesquiplane fighter of mixed construction, the Nieuport-Delage NiD 42, which was ordered in small numbers for the French air force, entering service in 1927.Donald 1997, p. 688. Nieuport developed three refined versions in 1927, the all-metal NiD-52 and NiD-72 and the mixed construction Nieuport-Delage NiD 62. Like the NiD 42 on which it was based, the NiD 52 was powered by a Hispano-Suiza 12Hb V12 engine, but the wooden monocoque rear fuselage was replaced by an equivalent made of duralumin and the wooden wing ribs by light alloy, while retaining a fabric covering. Both the main and secondary wings were of reduced area compared to the NiD-42, and an enlarged tail fitted in an ...

Spanish Republican Air Force
The Spanish Republican Air Force was the air arm of the Armed Forces of the Second Spanish Republic, the legally established government of Spain between 1931 and 1939. Initially divided into two branches: Military Aeronautics ('' Aeronáutica Militar'') and Naval Aeronautics ( ''Aeronáutica Naval''), the Republican Air Force became the Air Forces of the Spanish Republic, ''Fuerzas Aéreas de la República Española'' (FARE), also known as ''Arma de Aviación'', after it was reorganized following the restructuring of the Republican Armed Forces in September 1936, at the beginning of the Spanish Civil War. This defunct Air Force is largely known for the intense action it saw during the Civil War, from July 1936 till its disbandment in 1939. The Spanish Republican Air Force was popularly known as ''"La Gloriosa"'' (The Glorious One). But, according to some historians, the command structure of the Spanish loyalist forces was marred by ineptitude and lack of decision-making througho ...

Nationalist Faction (Spanish Civil War)
The Nationalist faction ( es, Bando nacional) or Rebel faction ( es, Bando sublevado) was a major faction in the Spanish Civil War of 1936 to 1939. It was composed of a variety of right-leaning political groups that supported the Spanish Coup of July 1936 against the Second Spanish Republic and Republican faction and sought to depose Manuel Azaña, including the Falange, the CEDA, and two rival monarchist claimants: the Alfonsist Renovación Española and the Carlist Traditionalist Communion. In 1937, all the groups were merged into the FET y de las JONS. After the death of the faction's early leaders, General Francisco Franco, one of the members of the 1936 coup, would head the Nationalists throughout most of the war and emerge as the dictator of Spain until his death in 1975. The term Nationalists or Nationals () was coined by Joseph Goebbels following the visit of the clandestine Spanish delegation led by Captain Francisco Arranz requesting war material on 24 July 1936, ...

Spanish Civil War
The Spanish Civil War ( es, Guerra Civil Española)) or The Revolution ( es, La Revolución, link=no) among Nationalists, the Fourth Carlist War ( es, Cuarta Guerra Carlista, link=no) among Carlists, and The Rebellion ( es, La Rebelión, link=no) or The Uprising ( es, La Sublevación, link=no) among Republicans. was a civil war in Spain fought from 1936 to 1939 between the Republicans and the Nationalists. Republicans were loyal to the left-leaning Popular Front government of the Second Spanish Republic, and consisted of various socialist, communist, separatist, anarchist, and republican parties, some of which had opposed the government in the pre-war period. The opposing Nationalists were an alliance of Falangists, monarchists, conservatives, and traditionalists led by a military junta among whom General Francisco Franco quickly achieved a preponderant role. Due to the international political climate at the time, the war had many facets and was variously viewed as cla ...
