Reduced Gravity Aircraft
A reduced-gravity aircraft is a type of fixed-wing aircraft that provides brief near-weightless environments for training astronauts, conducting research and making gravity-free movie shots. Versions of such airplanes were operated by the NASA Reduced Gravity Research Program, and one is currently operated by the Human Spaceflight and Robotic Exploration Programmes of the European Space Agency. The unofficial nickname "vomit comet" became popular among those who experienced their operation. History Parabolic flight as a way of simulating weightlessness was first proposed by the German aerospace engineer Fritz Haber and the German physicist Heinz Haber in 1950. Both had been brought to the US after World War II as part of Operation Paperclip. As well, Shih-Chun Wang studied nausea in astronauts for NASA, which helped lead to the creation of the vomit comet. Parabolic flights are sometimes used to examine the effects of weightlessness on a living organism. While humans are b ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |
Zero Gravity Flight Trajectory C9-565
0 (zero) is a number representing an empty quantity. In place-value notation such as the Hindu–Arabic numeral system, 0 also serves as a placeholder numerical digit, which works by multiplying digits to the left of 0 by the radix, usually by 10. As a number, 0 fulfills a central role in mathematics as the additive identity of the integers, real numbers, and other algebraic structures. Common names for the number 0 in English are ''zero'', ''nought'', ''naught'' (), ''nil''. In contexts where at least one adjacent digit distinguishes it from the letter O, the number is sometimes pronounced as ''oh'' or ''o'' (). Informal or slang terms for 0 include ''zilch'' and ''zip''. Historically, ''ought'', ''aught'' (), and ''cipher'', have also been used. Etymology The word ''zero'' came into the English language via French from the Italian , a contraction of the Venetian form of Italian via ''ṣafira'' or ''ṣifr''. In pre-Islamic time the word (Arabic ) had the meaning ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |
Ground Reaction Force
In physics, and in particular in biomechanics, the ground reaction force (GRF) is the force exerted by the ground on a body in contact with it. For example, a person standing motionless on the ground exerts a contact force on it (equal to the person's weight) and at the same time an equal and opposite ground reaction force is exerted by the ground on the person. In the above example, the ground reaction force coincides with the notion of a normal force. However, in a more general case, the GRF will also have a component parallel to the ground, for example when the person is walking – a motion that requires the exchange of horizontal (frictional) forces with the ground. The use of the word reaction derives from Newton's third law Newton's laws of motion are three basic laws of classical mechanics that describe the relationship between the motion of an object and the forces acting on it. These laws can be paraphrased as follows: # A body remains at rest, or in moti ..., ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |
CNES
The (CNES; French: ''Centre national d'études spatiales'') is the French government space agency (administratively, a "public administration with industrial and commercial purpose"). Its headquarters are located in central Paris and it is under the supervision of the French Ministries of Defence and Research. It operates from the Toulouse Space Centre and the Guiana Space Centre, but also has payloads launched from space centres operated by other countries. The president of CNES is Philippe Baptiste. CNES is a member of Institute of Space, its Applications and Technologies. It is Europe's largest and most important national organization of its type. History CNES was established under President Charles de Gaulle in 1961. It is the world's third oldest space agency, after the Soviet space program (Russia), and NASA (United States). CNES was responsible for the training of French astronauts, until the last active CNES astronauts transferred to the European Space Agency in 200 ...

Ecuadorian Air Force
The Ecuadorian Air Force ( es, Fuerza Aérea Ecuatoriana, FAE) is the Air arm of the Military of Ecuador and responsible for the protection of the Ecuadorian airspace. Mission To develop the military air wing, in order to execute institutional objectives which guarantee sovereignty and contribute towards the nation's security and development. Vision To be a dissuasive Air Force, respected and accepted by society, pioneering within the nation's "air-space" development. History The FAE was officially created on October 27, 1920. However, like in many other countries, military flying activity started before the formal date of birth of the Air Force. The history of Ecuador is marked by many skirmishes with its neighbour Peru. As a direct result of the 1910 Ecuador-Peru crisis the members of decided to expand their sporting activities into aviation as well. Renamed , they started an aviation school. Cosme Rennella Barbatto, an Italian living in Guayaquil, was one of the first memb ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |
Ecuadorian Civilian Space Agency
The Ecuadorian Civilian Space Agency (EXA; es, Agencia Espacial Civil Ecuatoriana) is a private Ecuadorian organization founded in 2007 that conducts research on space and planetary sciences. It is a non-profit non-governmental organization with civilian oversight. EXA had tested microgravity via Weightlessness#Reduced weight in aircraft, parabolic flight with the Ecuadorian Air Force. EXA launched Ecuador's first satellite, the CubeSat NEE-01 Pegaso, NEE-01 ''Pegaso'', in April 2013 aboard a Chinese Long March 2D.

North American Sabreliner
The North American Sabreliner, later sold as the Rockwell Sabreliner, is an American mid-sized business jet developed by North American Aviation. It was offered to the United States Air Force (USAF) in response to its Utility Trainer Experimental (UTX) program. It was named "Sabreliner" due to the similarity of the wing and tail to North American's F-86 Sabre jet fighter. Military variants, designated T-39 Sabreliner, were used by the USAF, United States Navy (USN), and United States Marine Corps (USMC) after the USAF placed an initial order in 1959.North American T-39A Sabreliner ". |

Falcon 20
The Dassault Falcon 20 is a French business jet developed and manufactured by Dassault Aviation. The first business jet developed by the firm, it became the first of a family of business jets to be produced under the same name; of these, both the smaller Falcon 10 and the larger trijet Falcon 50 were direct derivatives of the Falcon 20. Initially known as the Dassault-Breguet Mystère 20, approval to proceed with development of the aircraft was issued during December 1961. It is a low-wing monoplane design, powered by a pair of rear-mounted General Electric CF700 turbofan engines. On 4 May 1963, the prototype made its maiden flight. The first production aircraft was introduced on 3 June 1965. On 10 June 1965, French aviator Jacqueline Auriol achieved the women's world speed record using the first prototype. As a result of an early distributor arrangement with American airline Pan American (Pan Am), American-delivered aircraft were marketed under the name ''Fan Jet Falcon''; i ...
