Isamu Mochizuki
was an officer and ace fighter pilot in the Imperial Japanese Navy (IJN) during the Second Sino-Japanese War and the Pacific theater of World War II. He was officially credited with destroying ten enemy aircraft over China and the Pacific. He is famous for inventing the hineri-komi half-loop-and-roll technique that was employed in dogfighting by many Japanese fighter pilots. Career Mochizuki enlisted in IJN in 1925 and completed its pilot training program in November 1926. He first served on carrier ''Kaga'' and then on carrier ''Hōshō'', before he was transferred to a fighter squadron based at Ōmura Naval Air Station in Nagasaki Prefecture on Kyushu. In November 1932, he was transferred to Yokosuka Air Group, which was at the time considered an elite unit consisting of the very best fighter pilots in IJN. In November 1936, Mochizuki was promoted to Warrant Officer. At the outbreak of Second Sino-Japanese War he was transferred to the 13th Air Group that operated from S ...

Aircraft Principal Axes
An aircraft in flight is free to rotate in three dimensions: '' yaw'', nose left or right about an axis running up and down; ''pitch'', nose up or down about an axis running from wing to wing; and ''roll'', rotation about an axis running from nose to tail. The axes are alternatively designated as ''vertical'', ''lateral'' (or ''transverse''), and ''longitudinal'' respectively. These axes move with the vehicle and rotate relative to the Earth along with the craft. These definitions were analogously applied to spacecraft when the first manned spacecraft were designed in the late 1950s. These rotations are produced by torques (or moments) about the principal axes. On an aircraft, these are intentionally produced by means of moving control surfaces, which vary the distribution of the net aerodynamic force about the vehicle's center of gravity. Elevators (moving flaps on the horizontal tail) produce pitch, a rudder on the vertical tail produces yaw, and ailerons (flaps on the win ...

Rudder
A rudder is a primary control surface used to steer a ship, boat, submarine, hovercraft, aircraft, or other vehicle that moves through a fluid medium (generally aircraft, air or watercraft, water). On an aircraft the rudder is used primarily to counter adverse yaw and p-factor and is not the primary control used to turn the airplane. A rudder operates by redirecting the fluid past the hull (watercraft), hull or fuselage, thus imparting a turning or yaw (rotation), yawing motion to the craft. In basic form, a rudder is a flat plane or sheet of material attached with hinges to the craft's stern, tail, or after end. Often rudders are shaped so as to minimize Drag (physics), hydrodynamic or aerodynamic drag. On simple watercraft, a tiller—essentially, a stick or pole acting as a lever arm—may be attached to the top of the rudder to allow it to be turned by a helmsman. In larger vessels, cables, pushrods, or hydraulics may be used to link rudders to steering wheels. In typical air ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |
Dogfight
A dogfight, or dog fight, is an aerial battle between fighter aircraft conducted at close range. Dogfighting first occurred in Mexico in 1913, shortly after the invention of the airplane. Until at least 1992, it was a component in every major war, though with steadily declining frequency. Since then, longer-range weapons have made dogfighting largely obsolete. Modern terminology for air-to-air combat is air combat maneuvering (ACM), which refers to tactical situations requiring the use of individual basic fighter maneuvers (BFM) to attack or evade one or more opponents. This differs from aerial warfare, which deals with the strategy involved in planning and executing various missions. Etymology The term ''dogfight'' has been used for centuries to describe a melee: a fierce, fast-paced close quarters battle between two or more opponents. The term gained popularity during World War II, although its origin in air combat can be traced to the latter years of World War I. One of ...

Minoru Genda
was a Japanese military aviator and politician. He is best known for helping to plan the attack on Pearl Harbor. He was also the third Chief of Staff of the Japan Air Self-Defense Force. Early life Minoru Genda was the second son of a farmer from Kake, Hiroshima Prefecture, north of the city of Hiroshima. Two brothers were graduates of Tokyo University, another brother graduated from Chiba Medical College, and his youngest brother entered the Army Academy. Genda graduated from the Imperial Japanese Naval Academy in 1924 and took flight training for 11 months in 1928–1929, graduating with honors to become a fighter pilot. Early military service Genda was assigned to the aircraft carrier in 1931. He was well known in the navy, and in 1932 Genda formed a demonstration team at Yokosuka, leading a division of biplanes around the country, conducting aerobatic demonstrations. Known as "Genda's Flying Circus", the team, consisting of Genda, Yoshita Kobayashi and Motoharu Okamu ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |
Fixed-wing Aircraft
A fixed-wing aircraft is a heavier-than-air flying machine, such as an airplane, which is capable of flight using wings that generate lift caused by the aircraft's forward airspeed and the shape of the wings. Fixed-wing aircraft are distinct from rotary-wing aircraft (in which the wings form a rotor mounted on a spinning shaft or "mast"), and ornithopters (in which the wings flap in a manner similar to that of a bird). The wings of a fixed-wing aircraft are not necessarily rigid; kites, hang gliders, variable-sweep wing aircraft and airplanes that use wing morphing are all examples of fixed-wing aircraft. Gliding fixed-wing aircraft, including free-flying gliders of various kinds and tethered kites, can use moving air to gain altitude. Powered fixed-wing aircraft (airplanes) that gain forward thrust from an engine include powered paragliders, powered hang gliders and some ground effect vehicles. Most fixed-wing aircraft are flown by a pilot on board the craft, but some ar ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |
Battle Of Kwajalein
The Battle of Kwajalein was fought as part of the Pacific campaign of World War II. It took place from 31 January – 3 February 1944, on Kwajalein Atoll in the Marshall Islands. Employing the hard-learned lessons of the Battle of Tarawa, the United States launched a successful twin assault on the main islands of Kwajalein in the south and Roi-Namur in the north. The Japanese defenders put up stiff resistance, although outnumbered and under-prepared. The determined defense of Roi-Namur left only 51 survivors of an original garrison of 3,500. For the US, the battle represented both the next step in its island-hopping march to Japan and a significant morale victory because it was the first time the Americans had penetrated the "outer ring" of the Japanese Pacific sphere. For the Japanese, the battle represented the failure of the beach-line defense. Japanese defenses became prepared in depth, and the Battles of Peleliu, Guam, and the Marianas proved far more costly to the US. Back ...

Kuril Islands
The Kuril Islands or Kurile Islands (; rus, Кури́льские острова́, r=Kuril'skiye ostrova, p=kʊˈrʲilʲskʲɪjə ɐstrɐˈva; Japanese: or ) are a volcanic archipelago currently administered as part of Sakhalin Oblast in the Russian Far East. It stretches approximately northeast from Hokkaido in Japan to Kamchatka Peninsula in Russia separating the Sea of Okhotsk from the north Pacific Ocean. There are 56 islands and many minor rocks. The Kuril Islands consist of the Greater Kuril Chain and the Lesser Kuril Chain. They cover an area of around , with a population of roughly 20,000. The islands have been under Russian administration since their 1945 invasion as the Soviet Union towards the end of World War II. Japan claims the four southernmost islands, including two of the three largest ( Iturup and Kunashir), as part of its territory, as well as Shikotan and the Habomai islets, which has led to the ongoing Kuril Islands dispute. The disputed islands are k ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |
Ensign
An ensign is the national flag flown on a vessel to indicate nationality. The ensign is the largest flag, generally flown at the stern (rear) of the ship while in port. The naval ensign (also known as war ensign), used on warships, may be different from the civil ensign (merchant ships) or the yacht ensign (recreational boats). Large versions of naval ensigns called battle ensigns are used when a warship goes into battle. The ensign differs from the jack, which is flown from a jackstaff at the bow of a vessel. In its widest sense, an ensign is just a flag or other standard. The European military rank of ensign, once responsible for bearing a unit's standard (whether national or regimental), derives from it (in the cavalry, the equivalent rank was cornet, named after a type of flag). Ensigns, such as the ancient Roman ensigns in the Arch of Constantine, are not always flags. National ensigns In nautical use, the ensign is flown on a ship or boat to indicate its organizational ...
