Junkers Ju 87
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 known as Jericho trumpets, 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 attack dive even if the pilo ...

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''. 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 operate effectively. Method A dive bomber dives at a steep angle, normally between 45 and 60 degrees or ev ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |
Gull Wing
The gull wing is an aircraft wing configuration, known also as ''Pulaski wings'', with a prominent bend in the wing inner section towards the wing root. Its name is derived from the seabirds which it resembles. 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 various forms of gull wings. It rose to particular prominence in Poland, where the Polish aviation designer Zygmunt P ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |
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 transiting the ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |
Close Air Support
In military tactics, close air support (CAS) is defined as air action such as air strikes by fixed or rotary-winged aircraft against hostile targets near friendly forces and require detailed integration of each air mission with fire and movement of these forces and attacks with 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 Operations Forces (SOF) if the mission requires detailed integration with the fire and movement of those forces. A closely related subset of air interdiction (AI), battlefield air interdiction, denotes interdiction against units with near-term effects on friendly units, but which does not require integration with friendly troop movements.

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 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. Cause and effect Target fixation is caused by becoming focused on one thing that is usually distracting, dangerous, or rewarding. Focus can be caused by "anticipated success", such as when trying to arrive at a destination in a certain am ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |
G-force
The gravitational force equivalent, or, more commonly, g-force, is a measurement of the type of force per unit mass – typically acceleration – that causes a perception of weight, with a g-force of 1 g (not gram in mass measurement) equal to the conventional value of gravitational acceleration on Earth, ''g'', of about . Since g-forces indirectly produce weight, any g-force can be described as a "weight per unit mass" (see the synonym specific weight). 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 weight for every unit of each object's mass. The types of forces involved are transmitted through objects by interior mechanical stresses. Gravitational acceleration (except certain electromagnetic force influences) is the cause of an object's acceleration in relation to free fall. The g-force experienced by an object is due to the vector sum of all ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |
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 period. 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 progressively as: * ... [...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 air speed in a vertical dive. Most modern combat aircraft are equipped with air brakes, which perform the same function as dive brakes.

Blitzkrieg
Blitzkrieg ( , ; from 'lightning' + 'war') is a word used to describe a surprise attack using a rapid, overwhelming force concentration that may consist of armored and motorized or mechanized infantry formations, together with close air support, that has the intent to break through the opponent's lines of defense, then dislocate the defenders, unbalance 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 systematic application of the traditional German tactic of (maneuver warfare), deep penetrations and the bypassing of enemy strong points to encircle and destroy enemy forces in a (cauldron battle). During the Invasion of Poland, Western journalists adopted the term ''blitzkrieg'' to describe this form of armored warfare. The term had appeared in 1935, in a German military periodical (German Defen ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |

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 news and journalism, government, advertising, entertainment, education, and activism and is often associated with material which is prepared by governments as part of war efforts, political campaigns, health campaigns, revolutionaries, big businesses, ultra-religious organizations, the media, and certain individuals such as soapboxers. In the 20th century, the English term ''propaganda'' was often associated with a manipulative approach, but historically, propaganda has been a neutral descriptive term of any material that promotes certain opinions or ideologies. Equivalent non-English terms have also la ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |
