NBMR-3
NBMR-3 or NATO Basic Military Requirement 3 was a document produced by a North Atlantic Treaty Organisation (NATO) committee in the early 1960s detailing the specification of future combat aircraft designs. The requirement was for aircraft in two performance groups, supersonic fighter aircraft (NBMR-3a) and subsonic fighter-bomber aircraft (NBMR-3b). Both requirements specifically stated the need for V/STOL performance as the contemporary fear was that airfields could be overrun or disabled through Eastern Bloc hostile actions and that dispersed operating bases would be needed. Germany was planning replacements for the Fiat G.91 and Lockheed F-104G Starfighter using the new aircraft types. Aircraft manufacturing companies of European countries were invited to submit designs, from a short-list of 10 supersonic fighter designs two were chosen as the joint winners, the Hawker Siddeley P.1154 and Dassault Mirage IIIV. Disagreement over the balance between best performance aircraft an ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |
Dassault Mirage IIIV
The Dassault Mirage IIIV, also spelled Mirage III V, was a French vertical take-off and landing (VTOL) prototype fighter aircraft of the mid-1960s developed and produced by Dassault Aviation. The Mirage IIIV was a VTOL derivative of an existing conventional fighter, the Dassault Mirage III; the principal difference between the two types was the addition of eight small vertical lift jets which straddled the main engine. These lift jets would have been used during vertical takeoffs and landings, but would have been inactive during horizontal flight. The Mirage IIIV had come about as a response to the issuing of a NATO specification, NATO Basic Military Requirement 3 (NBMR-3), which sought a supersonic-capable VTOL strike fighter. The Mirage IIIV was a competitor with Hawker Siddeley's P.1154 VTOL fighter, a cousin of the Hawker Siddeley Harrier. Both aircraft competed to be selected to meet the NBMR-3 requirement. While the Mirage IIIV is commonly viewed as being more politicall ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |
VFW VAK 191B
The VFW VAK 191B was an experimental German vertical take-off and landing (VTOL) strike fighter of the early 1970s. VAK was the abbreviation for ''Vertikalstartendes Aufklärungs- und Kampfflugzeug'' (Vertical Take-off Reconnaissance and Strike Aircraft). Designed and built by the Vereinigte Flugtechnische Werke (VFW), it was developed with the purpose of eventually serving as a replacement for the Italian Fiat G.91 then in service with the German Air Force. Operationally, it was intended to have been armed with nuclear weapons as a deterrent against aggression from the Soviet Union and, in the event of a major war breaking out, to survive the first wave of attacks by deploying to dispersed locations, rather than conventional airfields, and to retaliate against targets behind enemy lines. The VAK 191B suffered from a protracted development cycle, spanning ten years between inception and flight, in part due to changing requirements, changing partnerships and the difficulties inhe ...

Fokker/Republic D-24 Alliance
The Fokker/Republic D.24 was a supersonic variable-sweep wing concept aircraft designed from 1962 to 1968 by the Fokker-Republic Alliance, a coalition between Fokker and Republic Aviation. The project was based out of Schiphol, Netherlands, and led by Alexander Wadkowski of Republic Aviation. Design The D.24 was designed to be capable of vertical take-off and landing (VTOL) and was designed in accordance with NATO Basic Military Requirement 3 and competed in NATO's BMR-3 military project bidding. Only a scale model was built and is now located at the Luchtvaartmuseum Aviodrome in Lelystad, Netherlands. Specifications See also *List of VTOL aircraft This is a list of fixed-wing aircraft capable of vertical take-off and landing arranged under manufacturer.

Nuclear Weapon
A nuclear weapon is an explosive device that derives its destructive force from nuclear reactions, either fission (fission bomb) or a combination of fission and fusion reactions ( thermonuclear bomb), producing a nuclear explosion. Both bomb types release large quantities of energy from relatively small amounts of matter. The first test of a fission ("atomic") bomb released an amount of energy approximately equal to . The first thermonuclear ("hydrogen") bomb test released energy approximately equal to . Nuclear bombs have had yields between 10 tons TNT (the W54) and 50 megatons for the Tsar Bomba (see TNT equivalent). A thermonuclear weapon weighing as little as can release energy equal to more than . A nuclear device no larger than a conventional bomb can devastate an entire city by blast, fire, and radiation. Since they are weapons of mass destruction, the proliferation of nuclear weapons is a focus of international relations policy. Nuclear weapons have been d ...

Altitude
Altitude or height (also sometimes known as depth) is a distance measurement, usually in the vertical or "up" direction, between a reference datum and a point or object. The exact definition and reference datum varies according to the context (e.g., aviation, geometry, geographical survey, sport, or atmospheric pressure). Although the term ''altitude'' is commonly used to mean the height above sea level of a location, in geography the term elevation is often preferred for this usage. Vertical distance measurements in the "down" direction are commonly referred to as depth. In aviation In aviation, the term altitude can have several meanings, and is always qualified by explicitly adding a modifier (e.g. "true altitude"), or implicitly through the context of the communication. Parties exchanging altitude information must be clear which definition is being used. Aviation altitude is measured using either mean sea level (MSL) or local ground level (above ground level, or ...

Nautical Miles
A nautical mile is a unit of length used in air, marine, and space navigation, and for the definition of territorial waters. Historically, it was defined as the meridian arc length corresponding to one minute ( of a degree) of latitude. Today the international nautical mile is defined as exactly . The derived unit of speed is the knot, one nautical mile per hour. Unit symbol There is no single internationally agreed symbol, with several symbols in use. * M is used as the abbreviation for the nautical mile by the International Hydrographic Organization. * NM is used by the International Civil Aviation Organization. * nmi is used by the Institute of Electrical and Electronics Engineers and the United States Government Publishing Office. * nm is a non-standard abbreviation used in many maritime applications and texts, including U.S. Government Coast Pilots and Sailing Directions. It conflicts with the SI symbol for nanometre. History The word mile is from the Latin word for ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |
Dassault Balzac V
The Dassault Balzac V was a French vertical takeoff and landing (VTOL) testbed of the early 1960s. It was built by Dassault Aviation from a prototype Mirage III aircraft to test the configuration for the Mirage IIIV. The sole example was badly damaged during an accident that occurred during its second flight test and was not repaired. Design and development Since the Rolls-Royce RB162 lift engines specified for the Mirage IIIV were not expected to be available before 1963, Dassault modified the first Mirage III prototype to serve as an interim VTOL testbed. Eight Rolls-Royce RB108 lift engines were installed, each with an average maximum takeoff thrust of 9.83 kN (2,210 lbf). The Mirage III's Snecma Atar G.2 propulsion engine was replaced with an unreheated (non-afterburning) Bristol Siddeley Orpheus BOr 3 with a thrust of 21.57 kN (4,850 lbf). The lift engines were grouped in tandem pairs around the aircraft's center of gravity on either side of the propul ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |
Vickers 585
Vickers was a British engineering company that existed from 1828 until 1999. It was formed in Sheffield as a steel foundry by Edward Vickers and his father-in-law, and soon became famous for casting church bells. The company went public in 1867, acquired more businesses, and began branching out into military hardware and shipbuilding. In 1911, the company expanded into aircraft manufacture and opened a flying school. They expanded even further into electrical and railway manufacturing, and in 1928 acquired an interest in the Supermarine. Beginning in the 1960s, various parts of the company were nationalised, and in 1999 the rest of the company was acquired by Rolls-Royce plc, who sold the defence arm to Alvis plc. The Vickers name lived on in Alvis Vickers, until the latter was acquired by BAE Systems in 2004 to form BAE Systems Land Systems.
