Chu XP-0
The Chu XP-0, also known as the Chu (AFAMF) XP-0, was a Chinese fighter prototype in the Second World War. Development Designed by the Chief of the Air Force Technical Bureau, Major General Chu Chia-Jen, in 1941, the XP-0 was a single-seat fighter monoplane, the single prototype of which was produced by AFAMF in 1943. Based largely on the Curtiss Hawk 75, it was of mixed construction with wooden three-spar wings, welded steel tube fuselage and plywood skinning. It could carry up to four 20 mm cannons underwing, and had capacity to carry bombs via a centreline bomb rack, allowing it to function as a dive bomber. Operational history It was anticipated that the XP-0 would be produced in series at AFAMF No. 1 factory at Kunming, however the prototype was flown for the first time in 1943, at Yangling. After circling the airfield, the XP-0 landed too fast, ground-looped and was written off. In the meantime, the American entry into World War II meant that American fighters wer ...

Republic Of China (1912–1949)
The Republic of China (ROC), between 1912 and 1949, was a sovereign state recognised as the official designation of China when it was based on Mainland China, prior to the Retreat of the government of the Republic of China to Taiwan, relocation of Government of the Republic of China, its central government to Taiwan as a result of the Chinese Civil War. At a Population history of China, population of 541 million in 1949, it was the List of countries and dependencies by population, world's most populous country. Covering , it consisted of 35 provinces of China, provinces, 1 Special administrative regions of China#ROC special administrative regions, special administrative region, 2 regions, 12 special municipality (Republic of China), special municipalities, 14 leagues, and 4 special banners. The China, People's Republic of China (PRC), which rules mainland China today, considers ROC as a country that ceased to exist since 1949; thus, the history of ROC before 1949 is often ...

Major General
Major general (abbreviated MG, maj. gen. and similar) is a military rank used in many countries. It is derived from the older rank of sergeant major general. The disappearance of the "sergeant" in the title explains the apparent confusion of a lieutenant general outranking a major general, whereas a major outranks a lieutenant. In the Commonwealth of Nations, Commonwealth and in the United States, when appointed to a field command, a major general is typically in command of a Division (military), division consisting of around 6,000 to 25,000 troops (several regiments or brigades). It is a two-star general, two-star rank that is subordinate to the rank of lieutenant general and senior to the rank of brigadier or brigadier general. In the Commonwealth, major general is equivalent to the navy rank of rear admiral. In air forces with a separate rank structure (Commonwealth), major general is equivalent to air vice-marshal. In some countries including much of Eastern Europe, major ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |
Curtiss Hawk 75
The Curtiss P-36 Hawk, also known as the Curtiss Hawk Model 75, is an American-designed and built fighter aircraft of the 1930s and 40s. A contemporary of the Hawker Hurricane and Messerschmitt Bf 109, it was one of the first of a new generation of combat aircraft—a sleek monoplane design with a retractable undercarriage making extensive use of metal in its construction. Perhaps best known as the predecessor of the Curtiss P-40 Warhawk, the P-36 saw little combat with the United States Army Air Forces during World War II. It was the fighter used most extensively and successfully by the French Air Force during the Battle of France. The P-36 was also ordered by the governments of the Netherlands and Norway but did not arrive in time to see action before both were occupied by Nazi Germany. The type was also manufactured under license in China, for the Republic of China Air Force, as well as in British India, for the Royal Air Force (RAF) and Royal Indian Air Force (RIAF). Axis ...

Kunming
Kunming (; ), also known as Yunnan-Fu, is the capital and largest city of Yunnan province, China. It is the political, economic, communications and cultural centre of the province as well as the seat of the provincial government. The headquarters of many of Yunnan's large businesses are in Kunming. It was important during World War II as a Chinese military center, American air base, and transport terminus for the Burma Road. In the middle of the Yunnan–Guizhou Plateau, Kunming is at an altitude of above sea level and a latitude just north of the Tropic of Cancer. As of 2020 census, Kunming had a total population of 8,460,088 inhabitants, of whom 5,604,310 lived in its built-up (or metro) area made of all urban districts but Jinning, not conurbated yet. It is at the northern edge of Dian Lake, surrounded by temples and lake-and-limestone hill landscapes. Kunming consists of an old, previously walled city, a modern commercial district, residential zones and university areas. ...

Ground Loop (aviation)
In aviation, a ground loop is a rapid rotation of a fixed-wing aircraft in the horizontal plane ( yawing) while on the ground. Aerodynamic forces may cause the advancing wing to rise, which may then cause the other wingtip to touch the ground. In severe cases (particularly if the ground surface is soft), the inside wing can dig in, causing the aircraft to swing violently or even cartwheel. In their early gliding experiments, the Wright Brothers referred to this action as ''well-digging''. Looping phenomenon In powered aeroplanes, the ground loop phenomenon is predominantly associated with aircraft that have conventional landing gear, due to the centre of gravity being positioned behind the main wheels. It may also occur with tricycle landing gear if excessive load is applied to the nosewheel, a condition known as wheel-barrowing. If the aircraft heading is different from the aircraft's direction of motion, a sideways force is exerted on the wheels. If this force is in front of t ...

World War II
World War II or the Second World War, often abbreviated as WWII or WW2, was a world war that lasted from 1939 to 1945. It involved the vast majority of the world's countries—including all of the great powers—forming two opposing military alliances: the Allies and the Axis powers. World War II was a total war that directly involved more than 100 million personnel from more than 30 countries. The major participants in the war threw their entire economic, industrial, and scientific capabilities behind the war effort, blurring the distinction between civilian and military resources. Aircraft played a major role in the conflict, enabling the strategic bombing of population centres and deploying the only two nuclear weapons ever used in war. World War II was by far the deadliest conflict in human history; it resulted in 70 to 85 million fatalities, mostly among civilians. Tens of millions died due to genocides (including the Holocaust), starvation, ma ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |
Republic Of China Air Force
The Republic of China Air Force, retroactively known by its historical name the Chinese Air Force and unofficially referred to as the Taiwanese Air Force, is the military aviation branch of the Republic of China Armed Forces, currently based in Taiwan. The ROCAF was founded in 1920 by the Kuomintang. While its historical name is sometimes used especially in domestic circles, it is not used as often internationally due to the current ambiguous political status of Taiwan and to avoid confusion with the People's Liberation Army Air Force of the People's Republic of China (PRC). Its primary mission is the defense of the airspace over and around the Taiwan area. Priorities of the ROCAF include the development of long range reconnaissance and surveillance networks, integrating C4ISTAR systems to increase battle effectiveness, procuring counterstrike weapons, next generation fighters, and hardening airfields and other facilities to survive a surprise attack. In May 2005, the Minist ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |
Pratt & Whitney R-1830-S1C3-G
The Pratt & Whitney R-1830 Twin Wasp is an American air-cooled radial aircraft engine. It displaces and its bore and stroke are both . The design traces its history to 1929 experiments at Pratt & Whitney on twin-row designs. Production began in 1932 and it was widely used during the 1930s. It was selected as the power plant for both the four-engined Consolidated B-24 Liberator heavy bomber and the twin-engined Douglas DC-3 transport, two of the most-produced aircraft. The production run of 173,618 R-1830 examples makes it the most-produced aviation engine in history. A further developed version, the R-2000, was produced starting in 1942. The R-2000 was "bored-out" to and had a number of other minor changes to improve fuel economy and allow it to run at higher power ratings on lower-octane fuel. The primary user of the R-2000 was the Douglas DC-4. Mostly retired today, the R-1830 is still used on Douglas DC-3 and various museum aircraft and warbirds seen at airshows. I ...

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 ...
