Ju 87 Stuka
The Junkers Ju 87, popularly known as the "Stuka", is a German dive bomber and ground-attack aircraft. Designed by Hermann Pohlmann, it first flew in 1935. The Ju 87 made its combat debut in 1937 with the Luftwaffe's Condor Legion during the Spanish Civil War of 1936–1939 and served the Axis powers, Axis in World War II from beginning to end (1939–1945). The aircraft is easily recognisable by its inverted gull wings and fixed Aircraft fairing, spatted Landing gear, undercarriage. Upon the leading edges of its faired main gear legs were mounted ram-air Siren (alarm), sirens, officially called "Lärmgerät" (noise device), which became a propaganda symbol of German Aerial warfare, air power and of the so-called ''Blitzkrieg'' victories of 1939–1942, as well as providing Stuka pilots with audible feedback as to speed. The Stuka's design included several innovations, including automatic pull-up dive brakes under both wings to ensure that the aircraft recovered from its attac ...

Dive Bomber
A dive bomber is a bomber aircraft that dives directly at its targets in order to provide greater accuracy for the bomb it drops. Diving towards the target simplifies the bomb's trajectory and allows the pilot to keep visual contact throughout the bomb run. This allows attacks on point targets and ships, which were difficult to attack with conventional level bombers, even ''en masse''. Dive bombing was especially effective against vehicles when integrated into early instances of Blitzkrieg. After World War II, the rise of precision-guided munitions and improved anti-aircraft defences—both fixed gunnery positions and fighter interception—led to a fundamental change in dive bombing. New weapons, such as rockets, allowed for better accuracy from smaller dive angles and from greater distances. They could be fitted to almost any aircraft, including fighters, improving their effectiveness without the inherent vulnerabilities of dive bombers, which needed air superiority to ...

Gull Wing
The gull wing, also known as Polish wing or Puławski wing, is an aircraft wing configuration with a prominent bend in the wing inner section towards the wing root. Its name is derived from the seabirds which it resembles and from the Polish aircraft designer Zygmunt Puławski who started using this design in his planes. Numerous aircraft have incorporated such wings for a diverse range of purposes. The gull wing was commonly used to improve visibility in a high wing arrangement, because such wing could be thinnest by the fuselage, and in theory should limit pilot's view no more than A-pillars of a windscreen in a car body. Gliders were the first aircraft to feature the gull wing, starting with the Weltensegler in 1921; it was not until the record-breaking Fafnir at the end of that decade did the configuration gain popularity. Beyond becoming popular for the next three decades amongst high-performance gliders, various ground-based aircraft and flying boats also adopted var ...

Invasion Of Poland
The invasion of Poland, also known as the September Campaign, Polish Campaign, and Polish Defensive War of 1939 (1 September – 6 October 1939), was a joint attack on the Second Polish Republic, Republic of Poland by Nazi Germany, the Slovak Republic (1939–1945), Slovak Republic, and the Soviet Union, which marked the beginning of World War II. The German invasion began on 1 September 1939, one week after the signing of the Molotov–Ribbentrop Pact between Germany and the Soviet Union, and one day after the Supreme Soviet of the Soviet Union had approved the pact. The Soviet invasion of Poland, Soviets invaded Poland on 17 September. The campaign ended on 6 October with Germany and the Soviet Union dividing and annexing the whole of Poland under the terms of the German–Soviet Frontier Treaty. The aim of the invasion was to disestablish Poland as a sovereign country, with its citizens destined for The Holocaust, extermination. German and Field Army Bernolák, Slovak forces ...

Maritime Interdiction
Maritime Interception (or naval interdiction) operations (MIOs) are naval operations that aim to delay, disrupt, or destroy enemy forces or supplies en route to the battle area before they do any harm against friendly forces, similar to air interdiction. Maritime interdiction took place in both World Wars, the First World War and Second World War during the Battle of the Atlantic campaigns (1914–1918) and (1939–1945). In several other campaigns, such as the Norwegian Campaign and the Battle of the Mediterranean, naval interdiction campaigns took place. Naval interdiction took place in the Persian Gulf, during Operation Southern Watch. They took place between the end of Operation Desert Storm in 1991 and the beginning of the Iraq War in 2003. These operations were conducted to ensure Saddam Hussein was not smuggling his oil out of Iraq, in violation of United Nations sanctions against Iraq. The operations involved the stopping and boarding of any and all ships transitin ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |
Close Air Support
Close air support (CAS) is defined as aerial warfare actions—often air-to-ground actions such as strafes or airstrikes—by military aircraft against hostile targets in close proximity to friendly forces. A form of fire support, CAS requires detailed integration of each air mission with fire and movement of all forces involved. CAS may be conducted using aerial bombs, glide bombs, missiles, rockets, autocannons, machine guns, and even directed-energy weapons such as lasers.''Close Air Support''. United States Department of Defense, 2014. The requirement for detailed integration because of proximity, fires or movement is the determining factor. CAS may need to be conducted during shaping operations with special forces if the mission requires detailed integration with the fire and movement of those forces. A closely related subset of air interdiction, battlefield air interdiction, denotes interdiction against units with near-term effects on friendly units, but which does not ...

Target Fixation
Target fixation is an attentional phenomenon observed in humans in which an individual becomes so focused on an observed object (be it a target or hazard) that they inadvertently increase their risk of colliding with the object. It is associated with scenarios in which the operator is in control of a high-speed vehicle or other mode of transportation, such as motorists, fighter pilots, race-car drivers, paragliders, and motorcyclists. In such cases, the observer may fixate so intently on the target that they steer in the direction of their gaze, which is often the ultimate cause of a collision. The term target fixation was originally used in World War II fighter-bomber pilot training to describe pilots flying into targets during a strafing or bombing run. In Season 10 Episode 6 of Frasier ''Frasier'' () is an American television sitcom that was broadcast on NBC for 11 seasons from September 16, 1993, to May 13, 2004.

G-force
The g-force or gravitational force equivalent is a Specific force, mass-specific force (force per unit mass), expressed in Unit of measurement, units of standard gravity (symbol ''g'' or ''g''0, not to be confused with "g", the symbol for grams). It is used for sustained accelerations that cause a perception of weight. For example, an object at rest on Earth's surface is subject to 1 ''g'', equaling the conventional value of gravitational acceleration on Earth, about . More transient acceleration, accompanied with significant jerk (physics), jerk, is called Shock (mechanics), ''shock''. When the g-force is produced by the surface of one object being pushed by the surface of another object, the reaction force to this push produces an equal and opposite force for every unit of each object's mass. The types of forces involved are transmitted through objects by interior Stress (mechanics), mechanical stresses. Gravitational acceleration is one cause of an object's accelera ...

G-LOC
g-force induced loss of consciousness (abbreviated as G-LOC, pronounced "JEE-lock") is a term generally used in aerospace physiology to describe a loss of consciousness occurring from excessive and sustained g-forces draining blood away from the brain causing cerebral hypoxia. The condition is most likely to affect pilots of high performance fighter and aerobatic aircraft or astronauts, but is possible on some extreme amusement park rides. G-LOC incidents have caused fatal accidents in high performance aircraft capable of sustaining high ''g'' for extended periods. High-g training for pilots of high performance aircraft or spacecraft often includes ground training for G-LOC in special centrifuges, with some profiles exposing pilots to 9 ''g''s for a sustained length of time. Effects of ''g''-forces Under increasing positive ''g''-force, blood in the body will tend to move from the head toward the feet. For higher intensity or longer duration, this can manifest progress ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |
Dive Brake
Dive brakes or dive flaps are deployed to slow down an aircraft when in a dive. They often consist of a metal flap that is lowered against the air flow, thus creating drag and reducing dive speed.Crane, Dale: ''Dictionary of Aeronautical Terms, third edition'', page 168. Aviation Supplies & Academics, 1997. In the past, dive brakes were mostly used on dive bombers, which needed to dive very steeply, but without exceeding their red line speed, in order to drop their bombs accurately. The airbrakes or spoilers fitted to gliders often function both as landing aids, to adjust the approach angle, and to keep the aircraft's speed below its maximum permissible indicated airspeed in a vertical dive. Most modern combat aircraft are equipped with air brakes, which perform the same function as dive brakes.

Blitzkrieg
''Blitzkrieg'(Lightning/Flash Warfare)'' is a word used to describe a combined arms surprise attack, using a rapid, overwhelming force concentration that may consist of armored and motorized or mechanized infantry formations, together with artillery, air assault, and close air support. The intent is to break through an opponent's lines of defense, dislocate the defenders, confuse the enemy by making it difficult to respond to the continuously changing front, and defeat them in a decisive : a battle of annihilation. During the interwar period, aircraft and tank technologies matured and were combined with the systematic application of the traditional German tactic of (maneuver warfare), involving the deep penetrations and the bypassing of enemy strong points to encircle and destroy opposing forces in a (cauldron battle/battle of encirclement). During the invasion of Poland, Western journalists adopted the term ''blitzkrieg'' to describe that form of armored warfare. The ...

Propaganda
Propaganda is communication that is primarily used to influence or persuade an audience to further an agenda, which may not be objective and may be selectively presenting facts to encourage a particular synthesis or perception, or using loaded language to produce an emotional rather than a rational response to the information that is being presented. Propaganda can be found in a wide variety of different contexts. Beginning in the twentieth century, the English term ''propaganda'' became associated with a Psychological manipulation, manipulative approach, but historically, propaganda had been a neutral descriptive term of any material that promotes certain opinions or ideology, ideologies. A wide range of materials and media are used for conveying propaganda messages, which changed as new technologies were invented, including paintings, cartoons, posters, pamphlets, films, radio shows, TV shows, and websites. More recently, the digital age has given rise to new ways of dissemina ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |
