Humu
The VL Humu (Whirlwind) is a Finnish fighter aircraft, designed by Valtion lentokonetehdas in 1944, and based on the American Brewster F2A Buffalo. Design and development The Finnish Air Force had acquired 40+ surplus B-239 naval variants of the Brewster Buffalo and put them to good use during the Winter War, so it was decided in 1942 to produce a copy due to aircraft shortages. Chief designer Martti Vainio, along with designers Torsti Verkkola, Arvo Ylinen at Valtion Lentokonetehdas were tasked with designing the new aircraft as well as a replacement wing made of wood instead of metal. The Humu was largely constructed out of wood due to scarcity of metals, but the frame was made from steel and its design followed closely that of the Brewster. It was planned that captured Soviet engines and instrument panels would be used. It was powered by a 930hp Shvetsov M-63 engine, previously tested on a Brewster. The wooden wing added 250 kg of extra weight and moving the fuels tanks from ... [...More Info...]       [...Related Items...]     OR:     [Wikipedia]   [Google]   [Baidu]   |

Brewster F2A Buffalo
The Brewster F2A Buffalo is an American fighter aircraft which saw service early in World War II. Designed and built by the Brewster Aeronautical Corporation, it was one of the first U.S. monoplanes with an arrestor hook and other modifications for aircraft carriers. The Buffalo won a competition against the Grumman F4F Wildcat in 1939 to become the U.S. Navy's first monoplane fighter aircraft. Although superior to the Grumman F3F biplane it replaced, and the early F4Fs,Wheeler 1992, p. 58. the Buffalo was largely obsolete when the United States entered the war, being unstable and overweight, especially when compared to the Japanese Mitsubishi A6M Zero. Several nations, including Finland, Belgium, Britain and the Netherlands, ordered the Buffalo. The Finns were the most successful with their Buffalos, flying them in combat against early Soviet fighters with excellent results.Ethell 1995, p. 212. During the Continuation War of 1941–1944, the B-239s (de-navalized F2A-1s) operate ... [...More Info...]       [...Related Items...]     OR:     [Wikipedia]   [Google]   [Baidu]   |

Valtion Lentokonetehdas
''Valtion lentokonetehdas'' (State aircraft factory) was a Finnish aircraft manufacturing company that was founded on 23 February 1928 from the IVL or I.V.L. factory (Ilmailuvoimien lentokonetehdas, Finnish Air Force Aircraft Factory), founded in 1921. The company was transferred from being subordinate to the Finnish Air Force to being subordinate to the Ministry of Defence. The company, and its products were named with the prefix VL. Island factory The company began its production at Suomenlinna and Santahamina in Helsinki. The factory did not have an airport, only the sea and sea ice could be used for take-off and landing. Most of the aircraft built in Helsinki were seaplanes. In Helsinki the aircraft built were small compared to the Bristol Blenheim bombers built under licence in the late 1930s. Much of the final assembly was done outdoors. The company was looking for a new production facility further away from the Soviet Union. Helsinki was seen as a bad location for an arm ...

LKk/42 Machine Gun
Browning Aircraft Machine Gun - F.N. Caliber 13.2 mm (french: Mitrailleuse d'Avion Browning - F.N. Calibre 13,2 mm), more commonly known as the ''13.2 mm FN Browning'', but also ''13.2 mm Browning-F.N.'', ''F.N. Caliber 13.2 mm'', ''FN Browning M.1939'' and the like, was a caliber, shell-firing, heavy machine gun for aircraft use, designed by Fabrique Nationale (F.N.) in Herstal, Belgium, as a private export venture during the final years prior to World War II. Even though it gained great interest during its limited time on the export market, it only managed to be exported to the air forces of Romania and Sweden prior to the German invasion of Belgium in 1940, later also being pirate produced in Finland with the help from Sweden. Development and description The 13.2 mm FN Browning was developed by FN as an improved version of the Browning air-cooled MG53 aircraft machine gun. Improvements to the original design included: making the weapon lighter, ... [...More Info...]       [...Related Items...]     OR:     [Wikipedia]   [Google]   [Baidu]   |

WikiProject Aircraft
A WikiProject, or Wikiproject, is a Wikimedia movement affinity group for contributors with shared goals. WikiProjects are prevalent within the largest wiki, Wikipedia, and exist to varying degrees within sister projects such as Wiktionary, Wikiquote, Wikidata, and Wikisource. They also exist in different languages, and translation of articles is a form of their collaboration. During the COVID-19 pandemic, CBS News noted the role of Wikipedia's WikiProject Medicine in maintaining the accuracy of articles related to the disease. Another WikiProject that has drawn attention is WikiProject Women Scientists, which was profiled by '' Smithsonian'' for its efforts to improve coverage of women scientists which the profile noted had "helped increase the number of female scientists on Wikipedia from around 1,600 to over 5,000".

Low-wing Aircraft
A monoplane is a fixed-wing aircraft configuration with a single mainplane, in contrast to a biplane or other types of multiplanes, which have multiple planes. A monoplane has inherently the highest efficiency and lowest drag of any wing configuration and is the simplest to build. However, during the early years of flight, these advantages were offset by its greater weight and lower manoeuvrability, making it relatively rare until the 1930s. Since then, the monoplane has been the most common form for a fixed-wing aircraft. Characteristics Support and weight The inherent efficiency of the monoplane is best achieved in the cantilever wing, which carries all structural forces internally. However, to fly at practical speeds the wing must be made thin, which requires a heavy structure to make it strong and stiff enough. External bracing can be used to improve structural efficiency, reducing weight and cost. For a wing of a given size, the weight reduction allows it to fly slower ...

Grumman F4F Wildcat
The Grumman F4F Wildcat is an American carrier-based fighter aircraft that entered service in 1940 with the United States Navy, and the British Royal Navy where it was initially known as the Martlet. First used by the British in the North Atlantic, the Wildcat was the only effective fighter available to the United States Navy and Marine Corps in the Pacific Theater during the early part of the Second World War. The disappointing Brewster Buffalo was withdrawn in favor of the Wildcat and replaced as aircraft became available. With a top speed of , the Wildcat was outperformed by the faster (), more maneuverable, and longer-ranged Mitsubishi A6M Zero. US Navy pilots, including John "Jimmy" Thach, a pioneer of fighter tactics to deal with the A6M Zero, were greatly dissatisfied with the Wildcat's inferior performance against the Zero in the battles of the Coral Sea and Midway. The Wildcat has a claimed air combat kill-to-loss ratio of 5.9:1 in 1942 and 6.9:1 for the entire war.Po ...
