Praga E-39
Praga E-39/BH-39 was a Czechoslovak trainer aircraft. History This aircraft was designed by Pavel Beneš and Miroslav Hajn, engineers at the Czech aviation company ČKD-Praga in 1931. It flew for the first time in June of that year. The biplane, standard configuration for that era, was an immediate success and orders were placed by the Czechoslovak Air Force that used them as elementary training aircraft at its flight schools throughout the 1930s. Pre-World War II production of the machine was 139 units. In 1939 following the German occupation of Bohemia and Moravia, Slovakia became an independent country. It was a German ally and its small air force was placed under Luftwaffe control. Ten of the Praga E-39s were initially used as trainers by the Slovak Air Force. During the German invasion of the Soviet Union they were transferred to the Soviet front where they were employed by the Slovaks as reconnaissance platforms in support of German ground forces. Other E-39s were used by ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |
ČKD-Praga
ČKD-Praga (Českomoravská-Kolben-Daněk Prague) was a Czechoslovakian aircraft manufacturer. The company was founded in 1915 as an engine manufacturing company, under the designation Praga. The company started designing aircraft in 1930–31 when the designers Pavel Beneš and Miroslav Hajn came to ČKD-Praga from Avia. Their first aircraft was the Praga E-39 from 1931. It was a military trainer, with a production run of 139 aircraft. ČKD-Praga developed several aircraft over the following years, but none exceeded prototype stage. Jaroslav Šlechta became chief designer in 1934 and designed the Praga E-114 Air Baby aircraft, which became a commercial success. The aircraft was sold to France, Iran, Romania and to Britain. Most of the British aircraft were manufactured locally in Manchester under a licence, by F. Hills & Sons as the Hillson Praga. 126 aircraft were ordered until 1946. Šlechta remained with Praga post war, designing the E-55 general purpose aircraft. ČKD-Praga ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |

Biplanes
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 als ...

1930s Czechoslovakian Military Trainer Aircraft
Year 193 ( CXCIII) was a common year starting on Monday (link will display the full calendar) of the Julian calendar. At the time, it was known as the Year of the Consulship of Sosius and Ericius (or, less frequently, year 946 ''Ab urbe condita''). The denomination 193 for this year has been used since the early medieval period, when the Anno Domini calendar era became the prevalent method in Europe for naming years.

Praga Aircraft
Praga is a district of Warsaw, Poland. It is on the east bank of the river Vistula. First mentioned in 1432, until 1791 it formed a separate town with its own city charter. History The historical Praga was a small settlement located at the eastern bank of the Vistula river, directly opposite the towns of Old Warsaw and Mariensztat, both being parts of Warsaw now. First mentioned in 1432, it derived its name from the Polish verb ''prażyć'', meaning ''to burn'' or ''to roast'', as it occupied a forested area that was burnt out to make place for the village. Separated from Warsaw by a wide river, it developed independently of the nearby city, and on 10 February 1648 king Władysław IV of Poland granted Praga with a city charter. However, as it was mostly a suburb and most buildings were wooden, the town was repeatedly destroyed by fires, floods and foreign armies. Currently the only surviving historical monument from that epoch is the Church of Our Lady of Loreto. Altho ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |

Slovak Insurgent Air Force
The Slovak Resistance Air Force (in Slovak: ''Slovenské povstalecké letectvo'') was an Allied air unit which fought against Axis forces in Slovakia and participated in the Slovak National Uprising in August–October 1944. History The Slovak National Uprising, organized by Slovak military resistance, began in unfavourable conditions on 29 August 1944. In the first few days the resistance lost major airfields in Piešťany, Spišská Nová Ves, Poprad, Vajnory near Bratislava and Trenčín, but they kept a large area in central Slovakia with Tri Duby airfield (today called Sliač Airport) and a temporary airstrip near Zolná. All military aircraft of the resistance air force formed a reconnaissance-bomber unit, called the Combined Squadron. It consisted of four Avia B-534 biplane fighters, three older Letov Š-328 light bombers, and two obsolete Bf 109E-4. They were later reinforced by two other Bf 109G-6s and one Focke-Wulf Fw 189, which escaped from eastern Slovakia t ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |
Royal Hungarian Air Force
The Hungarian Air Force ( hu, Magyar Légierő), is the air force branch of the Hungarian Defence Forces. The task of the current Hungarian Air Force is primarily defensive purposes. The flying units of the air force are organised into a single command; under the Air Command and Control Centre. History 1918 to pre–World War II Following the dissolution of the Austro-Hungarian Monarchy in 1918, a small air arm was established operating surviving aircraft from Hungarian factories and training schools. This air arm became the Hungarian Red Air Force under the short-lived Hungarian Soviet Republic, but was disbanded upon its downfall. World War II Under the Treaty of Trianon (1920), Hungary was forbidden from owning military aircraft. However, a secret air arm was gradually established under the cover of civilian flying clubs. During 1938, as a result of the Bled agreement, the existence of the Royal Hungarian Air Force ( hu, Magyar Királyi Honvéd Légierő (MKHL)), was ...

Czechoslovakian Air Force
The Czechoslovak Air Force (''Československé letectvo'') or the Czechoslovak Army Air Force (''Československé vojenské letectvo'') was the air force branch of the Czechoslovak Army formed in October 1918. The armed forces of Czechoslovakia ceased to exist on 31 December 1992. By the end of the year, all aircraft of the Czechoslovak Air Force were divided between the Czech Air Force and the Slovak Air Force. Organization On 30 October 1918, the establishment of Aviation Corps (''Letecký sbor'') marked the beginning of the Czechoslovak Air Force. Under the First Republic, the air force was an integral service of the Czechoslovak army. During peacetime, the army aviation was a subordinate agency of the Ministry of National Defence within its 3rd Department of Aviation (''III. odbor (letecký) Ministerstva národní obrany'') under the command of divisional general Jaroslav Fajfr (as of October 1938). It was anticipated that individual squadrons and flights would be attache ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |
