Neiva Universal
The Neiva N621 Universal is a Brazilian propeller-driven basic trainer and ground attack aircraft manufactured by Indústria Aeronáutica Neiva. It is a cantilever, low-wing monoplane of all-metal construction, with retractable undercarriage and side-by-side seating. Design and development The Universal was designed in 1963 as a new primary trainer for the Brazilian Air Force, as a replacement for the T-6 Texan and Fokker S-11/ S-12 types then in use. The prototype (Registration PP-ZTW) first flew on 29 April 1966. The Brazilian Air Force ordered 150 aircraft as the T-25 Universal, and increased this order in 1978 by an additional 28 aircraft. A further developed version (designated the YT-25B Universal II) first flew on 22 October 1978 but was not put into production. The Universal was also adopted as a counter-insurgency aircraft. It was later replaced by the Tucano in both the advanced training and attack roles, but it is still used as a primary and basic trainer at the ...

Indústria Aeronáutica Neiva
Indústria Aeronáutica Neiva is a subsidiary of Embraer which produces airplanes and aircraft components. Its main product is the Embraer EMB 202 Ipanema, the most employed agricultural aircraft in Brazil and the first alcohol-powered airplane. Neiva delivered more than 3,700 aircraft until early 2006. The company was founded in Rio de Janeiro, in 1954, by . It started as a glider manufacturer. It moved to Botucatu in 1956. The company produced many gliders and general aviation aircraft until March 11, 1980, when it was acquired by Embraer. After the acquisition, Neiva also started to produce the Ipanema and various components for Embraer aircraft, including the Embraer ERJ 145 family, the Embraer EMB 314 Super Tucano and the Embraer E-Jets. Neiva also produced the Embraer EMB 120 Brasilia The Embraer EMB 120 Brasilia is a twin-turboprop 30-passenger commuter airliner designed and manufactured by the Brazilian aircraft manufacturer Embraer.

Embraer EMB 312 Tucano
The Embraer EMB 312 Tucano (English: '' Toucan'') is a low-wing, tandem-seat, single-turboprop, basic trainer with counter-insurgency capability that was developed in Brazil. The Brazilian Air Force sponsored the EMB-312 project at the end of 1978. Design and development work began in 1979 on a low-cost, relatively simple new basic trainer with innovative features which eventually became the international standard for basic training aircraft. The prototype first flew in 1980, and initial production units were delivered in 1983. Production was initially supported by a local order for 118 aircraft, with options for an additional 50 units in October 1980. It was later matched by an Egyptian licence-produced purchase in 1993 and subsequently by an improved variant known as the Short Tucano, which was licence-produced in the United Kingdom. The Tucano made inroads into the military trainer arena and became one of Embraer's first international marketing successes. A total of 664 unit ...

1960s Brazilian Military Trainer Aircraft
Year 196 ( CXCVI) was a leap year starting on Thursday (link will display the full calendar) of the Julian calendar. At the time, it was known as the Year of the Consulship of Dexter and Messalla (or, less frequently, year 949 '' Ab urbe condita''). The denomination 196 for this year has been used since the early medieval period, when the Anno Domini calendar era became the prevalent method in Europe for naming years. Events By place Roman Empire * Emperor Septimius Severus attempts to assassinate Clodius Albinus but fails, causing Albinus to retaliate militarily. * Emperor Septimius Severus captures and sacks Byzantium; the city is rebuilt and regains its previous prosperity. * In order to assure the support of the Roman legion in Germany on his march to Rome, Clodius Albinus is declared Augustus by his army while crossing Gaul. * Hadrian's wall in Britain is partially destroyed.

Neiva Aircraft
Neiva () is the capital of the Department of Huila. It is located in the valley of the Magdalena River in south central Colombia with a population of about 357,392 inhabitants. It is one of the most important cities in southern Colombia, mainly because of its strategic geographical location. History Neiva was first founded in 1539 by Juan de Cabrera in an area now belonging to the municipality of Campoalegre. In 1550, Juan de Alonso y Arias relocated the city to the place that is now the municipality of Villavieja. At this location, the city was destroyed by indigenous tribes in 1560. The city was founded, at its current location, for the third and final time in 1612 by Diego de Ospina y Medinilla. Neiva became important during the colonial times because of its strategic location. It was located in the trade route that communicated the Viceroyalty of Peru with Bogotá and Caracas. The city was declared as the capital of the Province of Neiva, made up of the Neiva, La Plat ...

Constant Speed Propeller
In aeronautics, a variable-pitch propeller is a type of propeller (airscrew) with blades that can be rotated around their long axis to change the blade pitch. A controllable-pitch propeller is one where the pitch is controlled manually by the pilot. Alternatively, a constant-speed propeller is one where the pilot sets the desired engine speed ( RPM), and the blade pitch is controlled automatically without the pilot's intervention so that the rotational speed remains constant. The device which controls the propeller pitch and thus speed is called a propeller governor or constant speed unit. Reversible propellers are those where the pitch can be set to negative values. This creates reverse thrust for braking or going backwards without the need to change the direction of shaft revolution. Some aircraft have ground-adjustable propellers, however these are not considered variable-pitch. These are typically found only on light aircraft and microlights. Purpose When an aircraft is ...

Piston Engine
A reciprocating engine, also often known as a piston engine, is typically a heat engine that uses one or more reciprocating pistons to convert high temperature and high pressure into a rotating motion. This article describes the common features of all types. The main types are: the internal combustion engine, used extensively in motor vehicles; the steam engine, the mainstay of the Industrial Revolution; and the Stirling engine for niche applications. Internal combustion engines are further classified in two ways: either a spark-ignition (SI) engine, where the spark plug initiates the combustion; or a compression-ignition (CI) engine, where the air within the cylinder is compressed, thus heating it, so that the heated air ignites fuel that is injected then or earlier.''Thermodynamics: An Engineering Approach'' by Yunus A. Cengal and Michael A. Boles Common features in all types There may be one or more pistons. Each piston is inside a cylinder, into which a gas is int ...

Lycoming IO-540
The Lycoming O-540 is a family of air-cooled six-cylinder, horizontally opposed fixed-wing aircraft and helicopter engines of displacement, manufactured by Lycoming Engines. The engine is a six-cylinder version of the four-cylinder Lycoming O-360. Design and development Producing between these engines are installed in a large variety of aircraft. The main competitors are the Continental IO-520 and IO-550 series. An AEIO version was developed for high-performance competition aerobatics aircraft. Starting at the power was eventually increased to . The AEIO-540 family has achieved considerable success in aircraft such as the Extra 300, CAP 232, and Zivko Edge 540. Variants All engines have an additional prefix preceding the 540 to indicate the specific configuration of the engine. The numerous engine suffixes denote different accessories such as different manufacturers' carburetors, or different magnetos. ;O-540 :Standard, direct-drive, normally aspirated Opposed engine ...
