AV-8 Harrier
The McDonnell Douglas (now Boeing) AV-8B Harrier II is a single-engine ground-attack aircraft that constitutes the second generation of the Harrier family, capable of vertical or short takeoff and landing (V/STOL). The aircraft is primarily employed on light attack or multi-role missions, ranging from close air support of ground troops to armed reconnaissance. The AV-8B is used by the United States Marine Corps (USMC), the Spanish Navy, and the Italian Navy. A variant of the AV-8B, the British Aerospace Harrier II, was developed for the British armed forces, while another, the TAV-8B, is a dedicated two-seat trainer. The project that eventually led to the AV-8B's creation started in the early 1970s as a cooperative effort between the United States and United Kingdom, aimed at addressing the operational shortcomings of the first-generation Hawker Siddeley Harrier. Early efforts centered on a larger, more powerful Pegasus engine to dramatically improve the capabilities of t ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |
WikiProject Aircraft
A WikiProject, or Wikiproject, is an affinity group for contributors with shared goals within the Wikimedia movement. WikiProjects are prevalent within the largest wiki, Wikipedia, and exist to varying degrees within Wikimedia project, sibling projects such as Wiktionary, Wikiquote, Wikidata, and Wikisource. They also exist in different languages, and translation of articles is a form of their collaboration. During the COVID-19 pandemic, CBS News noted the role of Wikipedia's WikiProject Medicine in maintaining the accuracy of articles related to the disease. Another WikiProject that has drawn attention is WikiProject Women Scientists, which was profiled by ''Smithsonian Magazine, Smithsonian'' for its efforts to improve coverage of women scientists which the profile noted had "helped increase the number of female scientists on Wikipedia from around 1,600 to over 5,000".

Trainer Aircraft
A trainer is a class of aircraft designed specifically to facilitate flight training of pilots and aircrews. The use of a dedicated trainer aircraft with additional safety features—such as tandem flight controls, forgiving flight characteristics and a simplified cockpit arrangement—allows pilots-in-training to safely advance their skills in a more forgiving aircraft. Civilian pilots are normally trained in a light aircraft, with two or more seats to allow for a student and instructor. Tandem and side by side The two seating configurations for trainer aircraft are: pilot and instructor side by side, or in tandem, usually with the pilot in front and the instructor behind. The side-by-side seating configuration has the advantage that the pilot and instructor can see each other's actions, allowing the pilot to learn from the instructor and the instructor to correct the student pilot. The tandem configuration has the advantage of being closer to the normal working environment th ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |
Norman Schwarzkopf Jr
Herbert Norman Schwarzkopf Jr. ( ; 22 August 1934 – 27 December 2012) was a United States Army general. While serving as the commander of United States Central Command, he led all Coalition of the Gulf War, coalition forces in the Gulf War against Ba'athist Iraq. Born in Trenton, New Jersey, Schwarzkopf grew up in the United States and later in Iran. He was accepted by the United States Military Academy and was commissioned as a Second Lieutenant#United States, second lieutenant in the United States Army in 1956. After a number of initial training programs, Schwarzkopf interrupted a stint as an academy teacher and served in the Vietnam War, first as an adviser to the South Vietnamese Army and then as a battalion commander. Schwarzkopf was highly decorated in Vietnam and was awarded three Silver Stars, two Purple Hearts, and the Legion of Merit. Rising through the ranks after the Vietnam war, he later commanded the 24th Mechanized Infantry Division and was one of the commande ...

United States Army
The United States Army (USA) is the primary Land warfare, land service branch of the United States Department of Defense. It is designated as the Army of the United States in the United States Constitution.Article II, section 2, clause 1 of the United States Constitution (1789).See alsTitle 10, Subtitle B, Chapter 301, Section 3001 It operates under the authority, direction, and control of the United States Secretary of Defense, United States secretary of defense. It is one of the six armed forces and one of the eight uniformed services of the United States. The Army is the most senior branch in order of precedence amongst the armed services. It has its roots in the Continental Army, formed on 14 June 1775 to fight against the British for independence during the American Revolutionary War (1775–1783). After the Revolutionary War, the Congress of the Confederation created the United States Army on 3 June 1784 to replace the disbanded Continental Army.Library of CongressJournals ...

Humanitarian Intervention
Humanitarian intervention is the Use of force in international law, use or threat of military force by a state (or states) across borders with the intent of ending severe and widespread human rights violations in a state which has not given permission for the use of force. Humanitarian interventions are aimed at ending human rights violations of individuals other than the citizens of the intervening state. Humanitarian interventions are only intended to prevent human rights violations in extreme circumstances. Attempts to establish institutions and political systems to achieve positive outcomes in the medium- to long-run, such as peacekeeping, peace-building and development aid, do not fall under this definition of a humanitarian intervention. There is not one standard or legal definition of humanitarian intervention; the field of analysis (such as law, ethics or politics) often influences the definition that is chosen. Differences in definition include variations in whether huma ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |
Forward Operating Base
A forward operating base (FOB) is any secured forward operational level military position, commonly a military base, that is used to support strategic goals and tactical objectives. A FOB may contain an airbase, hospital, machine shop, and other logistical facilities. The base may be used for an extended period of time. FOBs are traditionally supported by main operating bases that are required to provide backup support to them. A FOB also improves reaction time to local areas as opposed to having all troops on the main operating base. Description In its most basic form, a forward operating base consists of a ring of barbed wire around a position with a fortified entry control point, or ECP. An ECP is a controlled entry and exit point of the FOB and typically has positions to protect personnel against personnel-borne improvised explosive devices ( PBIED) and vehicle-borne improvised explosive devices ( VBIED), plus blast mitigation with standoff protection. More advanced FOBs ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |
Amphibious Assault Ship
An amphibious assault ship is a type of warship employed to land and support ground forces on enemy territory during an armed conflict. The design evolved from aircraft carriers converted for use as helicopter carriers (which, as a result, are often mistaken for conventional fixed-wing aircraft carriers). Modern designs support amphibious landing craft, with most designs including a well deck. Like the aircraft carriers they were developed from, some amphibious assault ships also support V/STOL fixed-wing aircraft and have a secondary role as aircraft carriers. The role of the amphibious assault ship is fundamentally different from that of a standard aircraft carrier: its aviation facilities have the primary role of hosting helicopters to support forces ashore rather than to support strike aircraft. However, some are capable of serving in the sea-control role, embarking aircraft like Harrier or the new F-35B variant of the Lightning II fighters for combat air patrol and ...

Aircraft Carrier
An aircraft carrier is a warship that serves as a seagoing airbase, equipped with a full-length flight deck and hangar facilities for supporting, arming, deploying and recovering carrier-based aircraft, shipborne aircraft. Typically it is the capital ship of a naval fleet, fleet (known as a carrier battle group), as it allows a naval force to power projection, project seaborne naval aviation, air power far from homeland without depending on local airfields for staging area, staging aerial warfare, aircraft operations. Since their inception in the early 20th century, aircraft carriers have evolved from wooden vessels used to deploy individual tethered reconnaissance balloons, to nuclear marine propulsion, nuclear-powered supercarriers that carry dozens of fighter aircraft, fighters, strike aircraft, military helicopters, airborne early warning and control, AEW&Cs and other types of aircraft such as unmanned combat aerial vehicle, UCAVs. While heavier fixed-wing aircraft such as a ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |
Maiden Flight
The maiden flight, also known as first flight, of an aircraft is the first occasion on which it leaves the ground under its own power. The same term is also used for the first launch of rockets. In the early days of aviation it could be dangerous, because the exact handling characteristics of the aircraft were generally unknown. The maiden flight of a new type is almost invariably flown by a highly experienced test pilot. Maiden flights are usually accompanied by a chase plane, to verify items like altitude, airspeed, and general airworthiness. A maiden flight is only one stage in the development of an aircraft type. Unless the type is a pure research aircraft (such as the X-15), the aircraft must be tested extensively to ensure that it delivers the desired performance with an acceptable margin of safety. In the case of civilian aircraft, a new type must be certified by a governing agency (such as the Federal Aviation Administration in the United States) before it can enter ...

Aerodynamics
Aerodynamics () is the study of the motion of atmosphere of Earth, air, particularly when affected by a solid object, such as an airplane wing. It involves topics covered in the field of fluid dynamics and its subfield of gas dynamics, and is an important domain of study in aeronautics. The term ''aerodynamics'' is often used synonymously with gas dynamics, the difference being that "gas dynamics" applies to the study of the motion of all gases, and is not limited to air. The formal study of aerodynamics began in the modern sense in the eighteenth century, although observations of fundamental concepts such as aerodynamic drag were recorded much earlier. Most of the early efforts in aerodynamics were directed toward achieving Aircraft#Heavier-than-air – aerodynes, heavier-than-air flight, which was first demonstrated by Otto Lilienthal in 1891. Since then, the use of aerodynamics through mathematical analysis, empirical approximations, wind tunnel experimentation, and computer si ...

Fuselage
The fuselage (; from the French language, French ''fuselé'' "spindle-shaped") is an aircraft's main body section. It holds Aircrew, crew, passengers, or cargo. In single-engine aircraft, it will usually contain an Aircraft engine, engine as well, although in some amphibious aircraft the single engine is mounted on a hardpoint, pylon attached to the fuselage, which in turn is used as a floating Hull (watercraft), hull. The fuselage also serves to position the Flight control surfaces, control and Stabilizer (aeronautics), stabilization surfaces in specific relationships to Wing, lifting surfaces, which is required for aircraft stability and maneuverability. Types of structures Truss structure This type of structure is still in use in many lightweight aircraft using welding, welded steel tube trusses. A box truss fuselage structure can also be built out of wood—often covered with plywood. Simple box structures may be rounded by the addition of supported lightweight strin ...

Cockpit
A cockpit or flight deck is the area, on the front part of an aircraft, spacecraft, or submersible, from which a pilot controls the vehicle. The cockpit of an aircraft contains flight instruments on an instrument panel, and the controls that enable the pilot to fly the aircraft. In most airliners, a door separates the cockpit from the aircraft cabin. After the September 11, 2001 attacks, all major airlines fortified their cockpits against access by hijackers. Etymology The word cockpit seems to have been used as a nautical term in the 17th century, without reference to cock fighting. It referred to an area in the rear of a ship where the cockswain's station was located, the cockswain being the pilot of a smaller "boat" that could be dispatched from the ship to board another ship or to bring people ashore. The word "cockswain" in turn derives from the old English terms for "boat-servant" (''coque'' is the French word for "shell"; and ''swain'' was old English for boy ...
