Mitsubishi Ki-2
The was a light bomber built by Mitsubishi for the Imperial Japanese Army Air Service (IJAAS) in the 1930s. Its Allies of World War II, Allied World War II Allied names for Japanese aircraft, nickname was "Louise". Despite its antiquated appearance, the Ki-2 was successfully used in Manchukuo and in North China during the early stages of the Second Sino-Japanese War, in areas where danger from enemy fighter aircraft was minimal. It was later used in a Flight training, training role. Design and development The Ki-2 was a low-wing Cantilever#Aircraft, cantilever monoplane with corrugated metal alloy decking, twin Vertical stabilizer, fins with rudders, fixed divided landing gear and was powered by two Nakajima Kotobuki radial engines. Maximum speed was , normal range and maximum take-off weight . Single machine guns were mounted in a semi-enclosed nose and dorsal positions and it could carry a maximum bomb load of . The Ki-2 was, like its stable mate the Mitsubishi Ki-1, an ada ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |

Vertical Stabilizer
A vertical stabilizer or tail fin is the static part of the vertical tail of an aircraft. The term is commonly applied to the assembly of both this fixed surface and one or more movable rudders hinged to it. Their role is to provide control, stability and trim in yaw (also known as directional or weathercock stability). It is part of the aircraft empennage, specifically of its stabilizers. The vertical tail is typically mounted on top of the rear fuselage, with the horizontal stabilizers mounted on the side of the fuselage (a configuration termed "conventional tail"). Other configurations, such as T-tail or twin tail, are sometimes used instead. Vertical stabilizers have occasionally been used in motor sports, with for example in Le Mans Prototype racing. Function Principle The vertical tail of an aircraft typically consists of a fixed vertical stabilizer or fin on which a movable rudder is mounted. A trim tab may similarly be mounted on the rudder. Together, their role ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |
Manchurian Incident
The Mukden Incident, or Manchurian Incident, known in Chinese as the 9.18 Incident (九・一八), was a false flag event staged by Japanese military personnel as a pretext for the 1931 Japanese invasion of Manchuria. On September 18, 1931, Lieutenant Suemori Kawamoto of the Independent Garrison Unit of the 29th Japanese Infantry Regiment () detonated a small quantity of dynamite close to a railway line owned by Japan's South Manchuria Railway near Mukden (now Shenyang). The explosion was so weak that it failed to destroy the track, and a train passed over it minutes later. The Imperial Japanese Army accused Chinese dissidents of the act and responded with a full invasion that led to the occupation of Manchuria, in which Japan established its puppet state of Manchukuo six months later. The deception was exposed by the Lytton Report of 1932, leading Japan to diplomatic isolation and its March 1933 withdrawal from the League of Nations. The bombing act is known as the Liutiao ...

Prototype
A prototype is an early sample, model, or release of a product built to test a concept or process. It is a term used in a variety of contexts, including semantics, design, electronics, and Software prototyping, software programming. A prototype is generally used to evaluate a new design to enhance precision by system analysts and users. Prototyping serves to provide specifications for a real, working system rather than a theoretical one. In some design workflow models, creating a prototype (a process sometimes called materialization) is the step between the Formal specification, formalization and the evaluation of an idea. A prototype can also mean a typical example of something such as in the use of the derivation 'prototypical'. This is a useful term in identifying objects, behaviours and concepts which are considered the accepted norm and is analogous with terms such as stereotypes and archetypes. The word ''wikt:prototype, prototype'' derives from the Greek language, Greek ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |
Bristol Bulldog
The Bristol Bulldog is a British Royal Air Force single-seat biplane fighter designed during the 1920s by the Bristol Aeroplane Company. More than 400 Bulldogs were produced for the RAF and overseas customers, and it was one of the most famous aircraft used by the RAF during the inter-war period. Background The design of the Bulldog was the outcome of a series of design studies for fighters undertaken by Frank Barnwell during the 1920s. In 1924 Barnwell had started work on a fighter powered by the Rolls-Royce Falcon to meet the requirements of specification F.17/24. The project was shelved since Bristol preferred to use its own engine designs, but was revived in 1926 when Barnwell started work on a design, designated the Bristol 102, to meet either F.9/26 for a day-and-night fighter or N.21/26 for a shipborne fighter. The Type 105 designation was first applied to a subsequent proposal for another aircraft to meet F.9/26 powered by the Mercury engine then under develo ...

Malmö
Malmö (, ; da, Malmø ) is the largest city in the Swedish county (län) of Scania (Skåne). It is the third-largest city in Sweden, after Stockholm and Gothenburg, and the sixth-largest city in the Nordic region, with a municipal population of 350,647 in 2021. The Malmö Metropolitan Region is home to over 700,000 people, and the Øresund Region, which includes Malmö and Copenhagen, is home to 4 million people. Malmö was one of the earliest and most industrialised towns in Scandinavia, but it struggled to adapt to post-industrialism. Since the 2000 completion of the Öresund Bridge, Malmö has undergone a major transformation, producing new architectural developments, supporting new biotech and IT companies, and attracting students through Malmö University and other higher education facilities. Over time, Malmö's demographics have changed and by the turn of the 2020s almost half the municipal population had a foreign background. The city contains many histori ...

Limhamn
Limhamn () is, in an administrative sense, the southern district of Malmö Municipality in Sweden. Before 1915, Limhamn was (briefly) a town of its own. The population of Limhamn-Bunkeflo (including suburbs) is 31,000, of which 7,000 live in the southern suburbs Tygelsjö and Bunkeflostrand, and some live in neighbourhoods that are not usually counted to Limhamn proper. History Archeological findings revealed a stoneage village from the Ertebølle culture at Limhamn. The interpretation of Limhamn's fate in later times diverge. Limhamn is by some held to have been one of the more important fishing villages in Scania, with a population living of the sea and relatively stable in size through the centuries, but this opinion is not undisputed. Limestone has been quarried in Limhamns kalkbrott since the early 16th century or earlier, which can be inferred from the fact that king Christian II of Denmark (1513–1523) forbade the trade on the illegal harbour Limhamn. But only sin ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |
Junkers K 37
The Junkers S 36 was a twin-engine mail plane developed in Germany in the late 1920s that was further developed in Sweden as a multi-role military aircraft, albeit unsuccessfully, under the designation K 37. The design itself was a low-wing cantilever monoplane of largely conventional design, featuring twin tails and fixed, tailwheel undercarriage. Construction was metal throughout and skinned, in typical Junkers fashion, with corrugated duralumin. The engines were mounted in nacelles on the wings, and the crew was accommodated in three open cockpits, including one in the very nose of the aircraft. Design and development This design lent itself readily to military applications, and the open cockpit in the nose offered an ideal position for a crewman to act as an observer, bombardier and/or nose gunner. The ''S 36'' prototype was flown to Sweden, where it was militarised by Junkers subsidiary AB Flygindustri at Limhamn. Proposed as a fighter or reconnaissance-bomber, the K 37 cou ...

Mitsubishi Ki-1
The Mitsubishi Ki-1, also known as Mitsubishi Army Type 93 Heavy Bomber, was a bomber built by Mitsubishi for the Imperial Japanese Army in the 1930s. The Ki-1 design was heavily based on the Junkers K 37 and a mockup was ready in August 1932, with the first prototype being finished in March 1933. Despite its antiquated appearance, the Ki-1 was used in Manchukuo and in north China during the early stages of the Second Sino-Japanese War, in areas where danger from enemy fighter aircraft was minimal. Design and development The Mitsubishi Ki-1 was a low-wing, cantilever monoplane with fixed landing gear, twin fins and rudders, and was powered by two Mitsubishi Ha2-II water-cooled V-12 engines, giving a maximum speed of . The pilot and co-pilot were seated in tandem under an enclosed canopy, while gunners sat in semi-enclosed nose and dorsal gun turrets, each armed with a single machine gun. The usable bomb load was up to . The Ki-1 shared a similar configuration with the Junkers ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |
Machine Gun
A machine gun is a fully automatic, rifled autoloading firearm designed for sustained direct fire with rifle cartridges. Other automatic firearms such as automatic shotguns and automatic rifles (including assault rifles and battle rifles) are typically designed more for firing short bursts rather than continuous firepower, and are not considered true machine guns. As a class of military kinetic projectile weapon, machine guns are designed to be mainly used as infantry support weapons and generally used when attached to a bipod or tripod, a fixed mount or a heavy weapons platform for stability against recoils. Many machine guns also use belt feeding and open bolt operation, features not normally found on other infantry firearms. Machine guns can be further categorized as light machine guns, medium machine guns, heavy machine guns, general purpose machine guns and squad automatic weapons. Similar automatic firearms of caliber or more are classified as autocannons, rat ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |
Radial Engine
The radial engine is a reciprocating type internal combustion engine configuration in which the cylinders "radiate" outward from a central crankcase like the spokes of a wheel. It resembles a stylized star when viewed from the front, and is called a "star engine" in some other languages. The radial configuration was commonly used for aircraft engines before gas turbine engines became predominant. Engine operation Since the axes of the cylinders are coplanar, the connecting rods cannot all be directly attached to the crankshaft unless mechanically complex forked connecting rods are used, none of which have been successful. Instead, the pistons are connected to the crankshaft with a master-and-articulating-rod assembly. One piston, the uppermost one in the animation, has a master rod with a direct attachment to the crankshaft. The remaining pistons pin their connecting rods' attachments to rings around the edge of the master rod. Extra "rows" of radial cylinders can be added i ...
