1973 Paris Air Show Tu-144 Crash
The 1973 Paris Air Show Tu-144 crash was the destruction of the second production Tupolev Tu-144 at Goussainville, Val-d'Oise, France, which killed all six crew members and eight people on the The crash, at the Paris Air Show on Sunday, 3 June damaged the development program of the Tupolev Tu-144. One theory is that a French Mirage jet sent to photograph the aircraft without the knowledge of the Soviet crew caused the pilots to take evasive maneuvers, resulting in the Another theory is that in a rivalry with the Anglo-French Concorde, the pilots attempted a maneuver that was beyond the capabilities of Accident left, СССР-77102, the Tupolev Tu-144S involved in the accident, photographed in May 1973 The aircraft involved was Tupolev Tu-144S СССР-77102, manufacturer's serial number 01–2, the second production Tu-144.

Structural Failure
Structural integrity and failure is an aspect of engineering that deals with the ability of a structure to support a designed structural load (weight, force, etc.) without breaking and includes the study of past structural failures in order to prevent failures in future designs. Structural integrity is the ability of an item—either a structural component or a structure consisting of many components—to hold together under a load, including its own weight, without breaking or deforming excessively. It assures that the construction will perform its designed function during reasonable use, for as long as its intended life span. Items are constructed with structural integrity to prevent catastrophic failure, which can result in injuries, severe damage, death, and/or monetary losses. ''Structural failure'' refers to the loss of structural integrity, or the loss of load-carrying capacity in either a structural component or the structure itself. Structural failure is initiated ...

Marcel Dassault
Marcel Dassault (born Marcel Ferdinand Bloch; 23 January 1892 – 17 April 1986) was a French engineer and industrialist who spent his career in aircraft manufacturing. Early life and education Born on 23 January 1892 in Paris, he was the youngest of the four children of Adolphe Bloch, a doctor, and his wife Noémie Allatini. His parents were Jewish. He was educated at Lycée Condorcet in Paris. After studies in electrical engineering, he graduated from the Breguet School and Supaéro. At the latter school, Bloch was classmates with a Russian student named Mikhail Gurevich, who would later be instrumental in the creation of the MiG aircraft series. Career Bloch worked at the French Aeronautics Research Laboratory at Chalais-Meudon during World War I and invented a type of aircraft propeller subsequently used by the French army during the conflict. In 1916, with Henry Potez and Louis Coroller, he formed a company, the '' Société d'Études Aéronautiques'', to produce the ...

Industrial Espionage
Industrial espionage, economic espionage, corporate spying, or corporate espionage is a form of espionage conducted for commercial purposes instead of purely national security. While political espionage is conducted or orchestrated by governments and is international in scope, industrial or corporate espionage is more often national and occurs between companies or corporations. Forms of economic and industrial espionage Economic or industrial espionage takes place in two main forms. In short, the purpose of espionage is to gather knowledge about one or more organizations. It may include the acquisition of intellectual property, such as information on industrial manufacture, ideas, techniques and processes, recipes and formulas. Or it could include sequestration of proprietary or operational information, such as that on customer datasets, pricing, sales, marketing, research and development, policies, prospective bids, planning or marketing strategies or the changing composition ...

Canard (aeronautics)
In aeronautics, a canard is a wing configuration in which a small forewing or foreplane is placed forward of the main wing of a fixed-wing aircraft or a weapon. The term "canard" may be used to describe the aircraft itself, the wing configuration, or the foreplane.. Canard wings are also extensively used in guided missiles and smart bombs. The term "canard" arose from the appearance of the Santos-Dumont 14-bis of 1906, which was said to be reminiscent of a duck (''canard'' in French) with its neck stretched out in flight. Despite the use of a canard surface on the first powered aeroplane, the Wright Flyer of 1903, canard designs were not built in quantity until the appearance of the Saab Viggen jet fighter in 1967. The aerodynamics of the canard configuration are complex and require careful analysis. Rather than use the conventional tailplane configuration found on most aircraft, an aircraft designer may adopt the canard configuration to reduce the main wing loading, to ...

Chase Plane
A chase plane is an aircraft that "chases" a "subject" aircraft, spacecraft or rocket, for the purposes of making real-time observations and taking air-to-air photographs and video of the subject vehicle during flight. Background Safety can be one function of a chase plane; others are to photograph or video the target vehicle, or to collect engineering data from it. Chase planes may be used during flight tests, and for many years the best way to ensure the safety of an experimental aircraft was to fly alongside it and observe the flight. This "chase" airplane's crew would keep a constant lookout for problems with the "subject" or test aircraft, and if problems did arise, they would provide warnings and critical information to the test aircraft's crew, and to the mission controllers on the ground. They would also monitor the surrounding airspace for other aircraft that could pose a hazard to the flight, either by straying into their flightpath or threatening any kind of secre ...

Antonov An-22
The Antonov An-22 "Antei" (, ''An-22 Antej''; English ''Antaeus'') (NATO reporting name "Cock") is a heavy military transport aircraft designed by the Antonov Design Bureau in the Soviet Union. Powered by four turboprop engines each driving a pair of contra-rotating propellers, the design was the first wide-body transport aircraft and remains the world's largest turboprop-powered aircraft to date. The An-22 first appeared publicly outside the Soviet Union at the 1965 Paris Air Show. Thereafter, the model saw extensive use in major military and humanitarian airlifts for the Soviet Union, and is still in service with the Russian Air Force. Design and development In the late 1950s, the Soviet Union required a large military transport aircraft to supplement the Antonov An-8 and An-12s then entering service. Originally known as the An-20, the model is a conventional multi-engined high-wing design. In the early 1960s, the Antonov bureau produced a wooden mock up at its Kyiv, Uk ...

French Armed Forces
The French Armed Forces (french: Forces armées françaises) encompass the Army, the Navy, the Air and Space Force and the Gendarmerie of the French Republic. The President of France heads the armed forces as Chief of the Armed Forces. France has the sixth largest defence budget in the world and the first in the European Union (EU). It has the largest armed forces in size in the European Union. According to Credit Suisse, the French Armed Forces are ranked as the world's sixth-most powerful military. History The military history of France encompasses an immense panorama of conflicts and struggles extending for more than 2,000 years across areas, including modern France, greater Europe, and French territorial possessions overseas. According to British historian Niall Ferguson, the French participated in 50 of the 125 major European wars that have been fought since 1495; more than any other European state. They are followed by the Austrians who fought in 47 of them, the Sp ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |
September 11 Attacks
The September 11 attacks, commonly known as 9/11, were four coordinated suicide terrorist attacks carried out by al-Qaeda against the United States on Tuesday, September 11, 2001. That morning, nineteen terrorists hijacked four commercial airliners scheduled to travel from the Northeastern United States to California. The hijackers crashed the first two planes into the Twin Towers of the World Trade Center in New York City, and the third plane into the Pentagon (the headquarters of the United States military) in Arlington County, Virginia. The fourth plane was intended to hit a federal government building in Washington, D.C., but crashed in a field following a passenger revolt. The attacks killed nearly 3,000 people and instigated the war on terror. The first impact was that of American Airlines Flight 11. It was crashed into the North Tower of the World Trade Center complex in Lower Manhattan at 8:46 a.m. Seventeen minutes later, at 9:03, the World Trade Cen ...

Air France Flight 4590
On 25 July 2000, Air France Flight 4590, a Concorde passenger jet on an international charter flight from Paris to New York, crashed shortly after takeoff, killing all 109 people on board and four on the ground. It was the only fatal Concorde accident during its 27-year operational history. While taking off from Charles de Gaulle Airport, the aircraft ran over debris on the runway, causing a tyre to blow up and disintegrate. Tyre fragments, flung by the rapidly spinning wheel, violently struck the underside of the wing, damaging parts of the landing gear – thus preventing its retraction – and causing the integral fuel tank to rupture. Large amounts of fuel leaking from the rupture ignited, causing a loss of thrust in the left-hand-side engines 1 and 2. The aircraft lifted off, but the loss of thrust, high drag from the extended landing gear, and fire damage to the flight controls made it impossible to maintain control. The jet crashed into a hotel in nearby Gonesse two minut ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |
