T3 Hypersonic Wind Tunnel
The T3 Hypersonic Wind Tunnel is a hypersonic wind tunnel of the Institute for Advanced Studies (IEAv) of the Brazilian Air Force. The T3 is the largest hypersonic wind tunnel in Latin America.Tunel de vento hipersônico T3 entra em fase de qualificação. IEAv. Retrieved on 2011-01-18. . The tunnel is capable of producing airflow at speeds up to 25 times the speed of sound ( Mach 25). It was fully constructed by the IEAv with national technology. The tunnel is used by the and the |
Hypersonic Wind Tunnel
A hypersonic wind tunnel is designed to generate a hypersonic flow field in the working section, thus simulating the typical flow features of this flow regime - including compression shocks and pronounced boundary layer effects, entropy layer and viscous interaction zones and most importantly high total temperatures of the flow. The speed of these tunnels vary from Mach 5 to 15. The power requirement of a wind tunnel increases linearly with its cross section and flow density, but cubically with the test velocity required. Hence installation of a continuous, closed circuit wind tunnel remains a costly affair. The first continuous Mach 7-10 wind tunnel with 1x1 m test section was planned at Kochel am See, Germany during WW II and finally put into operation as 'Tunnel A' in the late 1950s at AEDC Tullahoma, TN, USA for an installed power of 57 MW. In view of these high facility demands, also intermittently operated experimental facilities like blow-down wind tunnels are designed an ...

Brazilian General Command For Aerospace Technology
The Brazilian Department of Science and Aerospace Technology ( pt, Departamento de Ciência e Tecnologia Aeroespacial; DCTA) is the national military research center for aviation and space flight. It is subordinated to the Brazilian Air Force (FAB). It coordinates all technical and scientific activities related to the aerospace sector in which there are interests by the Ministry of Defense. It was established in 1953. It currently employs several thousand civilian and military personnel. Institutes The DCTA has four institutes within its campus. Aeronautics and Space Institute (IAE) Aeronautics and Space Institute (). It develops projects in the aeronautical, airspace and defense sectors, co-responsible for the execution of the Brazilian Space Mission. Aeronautics Institute of Technology (ITA) Aeronautics Institute of Technology () is one of the main educational colleges of the Brazilian Air Force.

Latin America
Latin America or * french: Amérique Latine, link=no * ht, Amerik Latin, link=no * pt, América Latina, link=no, name=a, sometimes referred to as LatAm is a large cultural region in the Americas where Romance languages — languages derived from Latin — are predominantly spoken. The term was coined in the nineteenth century, to refer to regions in the Americas that were ruled by the Spanish, Portuguese and French empires. The term does not have a precise definition, but it is "commonly used to describe South America, Central America, Mexico, and the islands of the Caribbean." In a narrow sense, it refers to Spanish America plus Brazil (Portuguese America). The term "Latin America" is broader than categories such as ''Hispanic America'', which specifically refers to Spanish-speaking countries; and ''Ibero-America'', which specifically refers to both Spanish and Portuguese-speaking countries while leaving French and British excolonies aside. The term ''Latin America'' was f ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |
Mach Number
Mach number (M or Ma) (; ) is a dimensionless quantity in fluid dynamics representing the ratio of flow velocity past a boundary to the local speed of sound. It is named after the Moravian physicist and philosopher Ernst Mach. : \mathrm = \frac, where: : is the local Mach number, : is the local flow velocity with respect to the boundaries (either internal, such as an object immersed in the flow, or external, like a channel), and : is the speed of sound in the medium, which in air varies with the square root of the thermodynamic temperature. By definition, at Mach1, the local flow velocity is equal to the speed of sound. At Mach0.65, is 65% of the speed of sound (subsonic), and, at Mach1.35, is 35% faster than the speed of sound (supersonic). Pilots of high-altitude aerospace vehicles use flight Mach number to express a vehicle's true airspeed, but the flow field around a vehicle varies in three dimensions, with corresponding variations in local Mach number. The local spe ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |
Brazilian Space Agency
The Brazilian Space Agency ( pt, Agência Espacial Brasileira; AEB) is the civilian authority in Brazil responsible for the country's Space exploration, space program. It operates a spaceport at Centro de Lançamento de Alcântara, Alcântara, and a rocket launch site at Centro de Lançamento de Barreira do Inferno, Barreira do Inferno. It is the largest and most prominent space agency in Latin America. The Brazilian Space Agency is the institutional successor of Brazilian space program, Brazil's space program, which had been managed by the Military of Brazil, Brazilian military until its transfer to civilian control on 10 February 1994. It suffered a major setback in 2003, when a Brazilian rocket explosion, rocket explosion killed 21 technicians. Brazil successfully launched its first rocket into space, the VSB-30, on 23 October 2004 from the Centro de Lançamento de Alcântara, Alcântara Launch Center; several other successful launches have followed. Brazil was briefly a partn ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |
Military Equipment Of Brazil
A military, also known collectively as armed forces, is a heavily armed, highly organized force primarily intended for warfare. It is typically authorized and maintained by a sovereign state, with its members identifiable by their distinct military uniform. It may consist of one or more military branches such as an army, navy, air force, space force, marines, or coast guard. The main task of the military is usually defined as defence of the state and its interests against external armed threats. In broad usage, the terms ''armed forces'' and ''military'' are often treated as synonymous, although in technical usage a distinction is sometimes made in which a country's armed forces may include both its military and other paramilitary forces. There are various forms of irregular military forces, not belonging to a recognized state; though they share many attributes with regular military forces, they are less often referred to as simply ''military''. A nation's military may ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |
