Ozires Silva
Ozires Silva (born 8 January 1931) is a Brazilian entrepreneur who is the founder of Embraer. Ozires was born in Bauru–São Paulo state. He graduated on Escola de Aeronáutica do Campo dos Afonsos (Rio de Janeiro) as a military pilot. He then served the Brazilian Air Force for 4 years in the Amazon rainforest region. In 1962, Ozires graduated from the Aeronautics Technological Institute (ITA) as an aeronautical engineer. He was immediately hired by the Brazilian General Command for Aerospace Technology (CTA), where he would become part of the IPD - Instituto de Pesquisas e Desenvolvimento (current IAE - Instituto de Aeronáutica e Espaço). He soon became the lead engineer of the Bandeirante project. The first Bandeirante prototype flew on October 26, 1968. After that, Ozires attempted to convince private industries to produce the Bandeirante in series, without success. His efforts, however, contributed to the creation of a government-owned aircraft manufacturer, Embrae ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |
Brackets
A bracket is either of two tall fore- or back-facing punctuation marks commonly used to isolate a segment of text or data from its surroundings. They come in four main pairs of shapes, as given in the box to the right, which also gives their names, that vary between British English, British and American English. "Brackets", without further qualification, are in British English the ... marks and in American English the ... marks. Other symbols are repurposed as brackets in specialist contexts, such as International Phonetic Alphabet#Brackets and transcription delimiters, those used by linguists. Brackets are typically deployed in symmetric pairs, and an individual bracket may be identified as a "left" or "right" bracket or, alternatively, an "opening bracket" or "closing bracket", respectively, depending on the Writing system#Directionality, directionality of the context. In casual writing and in technical fields such as computing or linguistic analysis of grammar, brackets ne ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |
Aeronautics Technological Institute
Aeronautics is the science or art involved with the study, design, and manufacturing of air flight-capable machines, and the techniques of operating aircraft and rockets within the atmosphere. While the term originally referred solely to ''operating'' the aircraft, it has since been expanded to include technology, business, and other aspects related to aircraft. The term "aviation" is sometimes used interchangeably with aeronautics, although "aeronautics" includes lighter-than-air craft such as airships, and includes ballistic vehicles while "aviation" technically does not. A significant part of aeronautical science is a branch of dynamics called aerodynamics, which deals with the motion of air and the way that it interacts with objects in motion, such as an aircraft. History Early ideas Attempts to fly without any real aeronautical understanding have been made from the earliest times, typically by constructing wings and jumping from a tower with crippling or lethal res ...

Aerospace Engineers
Aerospace engineering is the primary field of engineering concerned with the development of aircraft and spacecraft. It has two major and overlapping branches: aeronautical engineering and astronautical engineering. Avionics engineering is similar, but deals with the electronics side of aerospace engineering. "Aeronautical engineering" was the original term for the field. As flight technology advanced to include vehicles operating in outer space, the broader term "aerospace engineering" has come into use. Aerospace engineering, particularly the astronautics branch, is often colloquially referred to as "rocket science". Overview Flight vehicles are subjected to demanding conditions such as those caused by changes in atmospheric pressure and temperature, with structural loads applied upon vehicle components. Consequently, they are usually the products of various technological and engineering disciplines including aerodynamics, air propulsion, avionics, materials science, stru ...

People From Bauru
The term "the people" refers to the public or common mass of people of a polity. As such it is a concept of human rights law, international law as well as constitutional law, particularly used for claims of popular sovereignty. In contrast, a people is any plurality of persons considered as a whole. Used in politics and law, the term "a people" refers to the collective or community of an ethnic group or nation. Concepts Legal Chapter One, Article One of the Charter of the United Nations states that "peoples" have the right to self-determination. Though the mere status as peoples and the right to self-determination, as for example in the case of Indigenous peoples (''peoples'', as in all groups of indigenous people, not merely all indigenous persons as in ''indigenous people''), does not automatically provide for independent sovereignty and therefore secession. Indeed, judge Ivor Jennings identified the inherent problems in the right of "peoples" to self-determination, as i ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |

Biotechnology
Biotechnology is a multidisciplinary field that involves the integration of natural sciences and Engineering Science, engineering sciences in order to achieve the application of organisms and parts thereof for products and services. Specialists in the field are known as biotechnologists. The term ''biotechnology'' was first used by Károly Ereky in 1919 to refer to the production of products from raw materials with the aid of living organisms. The core principle of biotechnology involves harnessing biological systems and organisms, such as bacteria, yeast, and plants, to perform specific tasks or produce valuable substances. Biotechnology had a significant impact on many areas of society, from medicine to agriculture to environmental science. One of the key techniques used in biotechnology is genetic engineering, which allows scientists to modify the genetic makeup of organisms to achieve desired outcomes. This can involve inserting genes from one organism into another, and con ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |
Turbo-prop
A turboprop is a gas turbine engine that drives an aircraft propeller. A turboprop consists of an intake, reduction gearbox, compressor, combustor, turbine, and a propelling nozzle. Air enters the intake and is compressed by the compressor. Fuel is then added to the compressed air in the combustor, where the fuel-air mixture then combusts. The hot combustion gases expand through the turbine stages, generating power at the point of exhaust. Some of the power generated by the turbine is used to drive the compressor and electric generator. The gases are then exhausted from the turbine. In contrast to a turbojet or turbofan, the engine's exhaust gases do not provide enough power to create significant thrust, since almost all of the engine's power is used to drive the propeller. Technological aspects Exhaust thrust in a turboprop is sacrificed in favor of shaft power, which is obtained by extracting additional power (beyond that necessary to drive the compressor) from turbine ...

Embraer EMB 121 Xingu
The Embraer EMB 121 Xingu (, named after the Xingu River) is a twin-turboprop fixed-wing aircraft built by the Brazilian aircraft manufacturer, Embraer. The design is based on the EMB 110 Bandeirante, using its wing and engine design merged with an all-new fuselage. The EMB 121 first flew on 10 October 1976.Michell 1994, p.9 A modified form of the EMB 121, the EMB 121A1 Xingu II, was introduced on 4 September 1981 with a more powerful engine (PT6A-135), increased seating (8 or 9 passengers) and a larger fuel capacity. Before production ceased in 1987, Embraer had produced 106 EMB 121 aircraft, 51 of which were exported to countries outside Brazil. Development and design In 1975, Embraer began development of a family of three derivatives of its Bandeirante airliner, all of which were to feature a pressurised fuselage and T-tail. The smallest of the three, and the first to be launched, was the EMB-121 Xingu, designed to carry six passengers in a typical layout, with a maximum o ...

1986 Brazilian UFO Incident
On May 19, 1986, a series of radar and visual contacts with unidentified flying objects (UFOs) took place across the Brazilian states of São Paulo, Rio de Janeiro, Minas Gerais and Goiás, becoming locally known as the "Night of the UFOs" (). Incident At around 8:15 p.m. BRT on the 19th of May 1986, Sérgio Mota da Silva, an air traffic controller at São José dos Campos Airport (SJK), spotted three bright lights hovering over the airport in the night sky, and Guarulhos International Airport detected contacts in the vicinity of São José dos Campos. Sérgio observed the objects with a pair of binoculars, noticing that they seemed to emit a bright red light, but often changing colors to yellow, green and orange-like. Dimming the runway lights, he noticed that the objects seemed to approach the airport, moving away once the lights were increased again. At 9:08 p.m. BRT, an EMB 121 Xingu plane, callsign PT-MBZ, on its way towards SJK from Brasília, reports seeing bri ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |
