PZL.54 Ryś
The PZL.48 Lampart (''leopard'') was a Polish heavy fighter-bomber design, that remained only a project, owing to the outbreak of World War II. Design and development The PZL.48 was a development of the heavy fighter-bomber PZL.38 Wilk, designed by Franciszek Misztal. Owing to problems with PZL.38's PZL Foka V8 engines and the excessive weight of the prototype it was decided in 1938 to build a variant of the plane using more powerful radial engines, named PZL.48 Lampart. Despite the new plane appearing almost identical to the PZL.38, apart from the engines, it was, in fact, redesigned in order to decrease weight. French 640 hp Gnome-Rhône 14M engines of small diameter were chosen. The building of a prototype started in 1939, but by the summer of 1939, only a wing had been made, while the fuselage was still under construction. It was planned to carry out static trials in Autumn 1939 and to fly the prototype in the first half of 1940. Further plans were to produce 110 Lamparts ...

Fighter-bomber
A fighter-bomber is a fighter aircraft that has been modified, or used primarily, as a light bomber or attack aircraft. It differs from bomber and attack aircraft primarily in its origins, as a fighter that has been adapted into other roles, whereas bombers and attack aircraft are developed specifically for bombing and attack roles. Although still used, the term fighter-bomber has less significance since the introduction of rockets and guided missiles into aerial warfare. Modern aircraft with similar duties are now typically called multirole combat aircraft or strike fighters. Development Prior to World War II, general limitations in available Aircraft engine, engine and Aerospace engineering, aeronautical technology required that each proposed military aircraft have its design tailored to a specific prescribed role. Reciprocating engine, Engine power grew dramatically during the early period of the war, roughly doubling between 1939 and 1943. The Bristol Blenheim, a typical ...

1930s Polish Fighter Aircraft
Year 193 ( CXCIII) was a common year starting on Monday 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.

Fw 187
The Focke-Wulf Fw 187 ''Falke'' ("Falcon") was a German aircraft designed in 1935. It was conceived by Kurt Tank as a twin-engine, high-performance fighter, but the ''Luftwaffe'' saw no role for the design, perceiving it as intermediate between the Messerschmitt Bf 109 and Bf 110. Later prototypes were adapted to two-seats to compete with the Bf 110 in the heavy fighter (''Zerstörer'') role, but only nine aircraft were built in total. Design and development In the early to mid-1930s, developments in airframe design outpaced available aircraft engine power. Consequently, some designs with two engines outperformed aircraft with just one engine. In European air races, the Dornier Do 17 - a military design concealed under the guise of civilian use - proved faster than single-engined fighters. Although the period of twin-engine superiority was brief, it sparked the idea in Nazi Germany of the "''schnellbomber''" (fast bomber), which defensive fighters could not catch. Other air forc ...

Kawasaki Ki-45
The Kawasaki Ki-45 ''Toryu'' (屠龍, "Dragonslayer") is a two-seat, twin-engine heavy fighter used by the Imperial Japanese Army in World War II. The army gave it the designation ; the Allied reporting name was "Nick". Originally serving as a long-range escort-fighter, the design — as with most heavy fighters of the period — fell prey to smaller, lighter, more agile single-engine fighters. As such, the Ki-45 instead served as a day and nighttime interceptor and strike fighter. Design and development In response to the rapid emergence in Europe of twin-engine heavy fighters such as the Messerschmitt Bf 110, the army ordered development of a twin-engine, two-seat fighter in 1937, and assigned the proposal by Kawasaki Shipbuilding the designation of ''Ki-38''. This only went as far as a mock up, but by December of that year the army ordered a working prototype as the ''Ki-45'', which first flew in January 1939. Results from the test flights, however, did not meet the arm ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |
Fokker G
Fokker (; ) was a Dutch aircraft manufacturer that operated from 1912 to 1996. The company was founded by the Dutch aviator Anthony Fokker and became famous during World War I for its fighter aircraft. During its most successful period in the 1920s and 1930s, Fokker dominated the civil aviation market. The company's fortunes declined over the course of the late 20th century; it declared bankruptcy in 1996, and its operations were sold to competitors. History Fokker in Germany At age 20, while studying in Germany, Anthony Fokker built his initial aircraft, the ''Spin'' (Spider)—the first Dutch-built plane to fly in his home country. Taking advantage of better opportunities in Germany, he moved to Berlin, where in 1912, he founded his first company, Fokker Aeroplanbau, later moving to the Görries suburb just southwest of Schwerin (at ), where the current company was founded, as Fokker Aviatik GmbH, on 12 February 1912. World War I Fokker capitalized on having sold several Fo ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |
Potez 630
The Potez 630 and its derivatives were a family of twin-engined, multirole aircraft developed for the French Air Force in the late 1930s. The design was a contemporary of the British Bristol Blenheim (which was larger and designed purely as a bomber) and the German Messerschmitt Bf 110 (which was designed purely as a fighter). The Potez 630 was in use by several operators during the Second World War. Following the Battle of France, both the Vichy French Air Force and Free French Air Forces used the type; a number of captured aircraft were operated by several air wings of the Axis powers. After the end of the conflict in 1945, a handful of aircraft were used for training purposes for some time. Development Origins On 31 October 1934, the French Ministry of Air issued a specification for a heavy fighter. The specification demanded the aircraft be capable of performing three principal roles: fighter direction, in which it was required to lead formations of single-engine fighters ...

Messerschmitt Bf 110
The Messerschmitt Bf 110, often known unofficially as the Me 110,Because it was built before ''Bayerische Flugzeugwerke'' became Messerschmitt AG in July 1938, the Bf 110 was never officially given the designation Me 110. is a twin-engined (destroyer, heavy fighter), fighter-bomber (''Jagdbomber'' or ''Jabo''), and night fighter (''Nachtjäger'') designed by the German aircraft company Bayerische Flugzeugwerke (BFW) and produced by successor company Messerschmitt. It was primarily operated by the ''Luftwaffe'' and was active throughout the Second World War. Development of the Bf 110 commenced during the first half of the 1930s; one early proponent of the type was Hermann Göring, who believed its heavy armament, speed, and range would make it the premier offensive fighter of the ''Luftwaffe''. Early variants were armed with a pair of MG FF 20 mm cannon, four 7.92 mm (.323 in) MG 17 machine guns, and one 7.92 mm (.323 in) MG 15 machine gun for defence (late ...

Horsepower
Horsepower (hp) is a unit of measurement of power, or the rate at which work is done, usually in reference to the output of engines or motors. There are many different standards and types of horsepower. Two common definitions used today are the imperial horsepower as in "hp" or "bhp" which is about , and the metric horsepower as in "cv" or "PS" which is approximately . The electric horsepower "hpE" is exactly , while the boiler horsepower is 9809.5 or 9811 watts, depending on the exact year. The term was adopted in the late 18th century by Scottish engineer James Watt to compare the output of steam engines with the power of draft horses. It was later expanded to include the output power of other power-generating machinery such as piston engines, turbines, and electric motors. The definition of the unit varied among geographical regions. Most countries now use the SI unit watt for measurement of power. With the implementation of the EU Directive 80/181/EEC on 1 January 201 ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |
Duraluminium
Duralumin (also called duraluminum, duraluminium, duralum, dural(l)ium, or dural) is a trade name for one of the earliest types of age-hardenable aluminium–copper alloys. The term is a combination of ''Düren'' and ''aluminium'' . Its use as a trade name is obsolete. Today the term mainly refers to aluminium-copper alloys, designated as the 2000 series by the international alloy designation system (IADS), as with 2014 and 2024 alloys used in airframe fabrication. Duralumin was developed in 1909 in Germany. Duralumin is known for its strength and hardness, making it suitable for various applications, especially in the aviation and aerospace industry. However, it is susceptible to corrosion, which can be mitigated by using alclad-duralum materials. History Duralumin was developed by the German metallurgist Alfred Wilm at private military-industrial laboratory (Center for Scientific-Technical Research) in Neubabelsberg. In 1903, Wilm discovered that after quenching, an alumi ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |
Polish Army
The Land Forces () are the Army, land forces of the Polish Armed Forces. They currently contain some 110,000 active personnel and form many components of the European Union and NATO deployments around the world. Poland's recorded military history stretches back a millennium – since the 10th century (see List of Polish wars and History of the Polish Army). Poland's modern army was formed after Poland Partitions of Poland, regained independence following World War I in 1918. History 1918–1938 When Poland History of Poland (1918–1939), regained independence in 1918, it recreated its military which participated in the Polish–Soviet War of 1919–1921, and in the two smaller conflicts ( Polish–Ukrainian War (1918–1919) and the Polish–Lithuanian War (1919–1920)). Initially, right after the First World War, Poland had five military districts (1918–1921): * Poznań Military District (Poznański Okręg Wojskowy), HQ in Poznań * Kraków Military District (Krakowski ...

Hispano Suiza 12Z
The 12Z, designated Type 89 by the company, was the final production evolution of the series of Hispano-Suiza V-12 aircraft engines. The Z model was in the middle of development when France fell to the Germans during World War II. A small number were produced before and during the war but following the occupation of Vichy France, the German occupation government did not allow full-scale production to start. After the war development would resume and small numbers were built to equip new designs, but the rapid introduction of the jet engine ended further development. Design and development The 12Z differed from the earlier 12Y primarily in the use of four valves per cylinder operated by dual overhead cams, as opposed to two valves operated by a single camshaft. This gave the cylinders considerably better volumetric efficiency and faster operation, raising the RPM from 2,400 to 2,700. As with the later variants of the 12Y, the engine was designed to run on 100 octane fuel as well ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |
