French Air And Space Force
The French Air and Space Force (AAE) (french: Armée de l'air et de l'espace, ) is the air and space force of the French Armed Forces. It was the first military aviation force in history, formed in 1909 as the , a service arm of the French Army; it became an independent military branch in 1934 as the French Air Force. On 10 September 2020, it assumed its current name, the French Air and Space Force, to reflect an "evolution of its mission" into the area of outer space. The number of aircraft in service with the French Air and Space Force varies depending on the source; the Ministry of Armed Forces gives a figure of 658 aircraft in 2014. According to 2018 data, this figure includes 210 combat aircraft: 115 Dassault Mirage 2000 and 95 Dassault Rafale. As of 2021, the French Air and Space Force employs a total of 40,500 regular personnel, with a reserve element of 5,187 in 2014.

Pratt & Whitney Canada PT6A-135
The Pratt & Whitney Canada PT6 is a turboprop aircraft engine produced by Pratt & Whitney Canada. Its design was started in 1958, it first ran in February 1960, first flew on 30 May 1961, entered service in 1964 and has been continuously updated since. It consists of two basic sections: a gas generator with accessory gearbox and a free power turbine with reduction gearbox, and is often seemingly mounted backwards in an aircraft in so far as the intake is at the rear and the exhaust at the front. Many variants of the PT6 have been produced, not only as turboprops but also as turboshaft engines for helicopters, land vehicles, hovercraft, and boats; as auxiliary power units; and for industrial uses. By November 2015, 51,000 had been produced, had logged 400 million flight hours from 1963 to 2016. It is known for its reliability with an in-flight shutdown rate of 1 per 651,126 hours in 2016.

Low-wing Aircraft
A monoplane is a fixed-wing aircraft configuration with a single mainplane, in contrast to a biplane or other types of multiplanes, which have multiple planes. A monoplane has inherently the highest efficiency and lowest drag of any wing configuration and is the simplest to build. However, during the early years of flight, these advantages were offset by its greater weight and lower manoeuvrability, making it relatively rare until the 1930s. Since then, the monoplane has been the most common form for a fixed-wing aircraft. Characteristics Support and weight The inherent efficiency of the monoplane is best achieved in the cantilever wing, which carries all structural forces internally. However, to fly at practical speeds the wing must be made thin, which requires a heavy structure to make it strong and stiff enough. External bracing can be used to improve structural efficiency, reducing weight and cost. For a wing of a given size, the weight reduction allows it to fly slower ...

T-tail Aircraft
A T-tail is an empennage wikt:configuration, configuration in which the tailplane is mounted to the top of the vertical stabilizer, fin. The arrangement looks like the capital letter T, hence the name. The T-tail differs from the standard configuration in which the tailplane is mounted to the fuselage at the base of the fin. Advantages T-tails were common in early jet aircraft. Designers were worried that an engine failure would otherwise damage the horizontal tail. The T-tail is very common on aircraft with engines mounted in nacelles on a Wing_configuration#Number_and_position_of_main_planes, high-winged aircraft or on aircraft with the engines mounted on the rear of the fuselage, as it keeps the tail clear of the jet exhaust. Rear-mounting the engines keeps the wings clean and improves short-field performance. This was necessary in early jet aircraft with less powerful engines. T-tail aircraft can have better short-field performance, such as on the British Aerospace ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |
Embraer Aircraft
Embraer S.A. () is a Brazilian multinational aerospace manufacturer that produces commercial, military, executive and agricultural aircraft, and provides aeronautical services. It was founded in 1969 in São José dos Campos, São Paulo, where its headquarters are located. The company is the third largest producer of civil aircraft, after Boeing and Airbus. History Seeking to develop a domestic aircraft industry, the Brazilian government under Getúlio Vargas' Estado Novo made several investments in the aerospace industry during the 1940s and 1950s. However, it was not until 1969, following the rise to power of a military junta in the 1964 Brazilian coup d'état, that Empresa Brasileira de Aeronáutica (Embraer) was created as a government-owned corporation.. Its first president, Ozires Silva, was a government appointee, and the company initially only produced a turboprop passenger aircraft, the Embraer EMB 110 Bandeirante. Early growth The Brazilian government contributed to E ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |

Beechcraft King Air
The Beechcraft King Air is a line of American utility aircraft produced by Beechcraft. The King Air line comprises a number of twin-turboprop models that have been divided into two families. The Model 90 and 100 series developed in the 1960s are known as King Airs, while the later T-tail Model 200 and 300 series were originally marketed as Super King Airs, with the name "Super" being dropped by Beechcraft in 1996 (although it is still often used to differentiate the 200 and 300 series King Airs from their smaller stablemates). The King Air was the first aircraft in its class and was produced continuously from 1964 to 2021. It outsold all of its turboprop competitors combined. It has recently faced competition from jet aircraft such as the Embraer Phenom 100, Honda HA-420 HondaJet and Cessna Citation Mustang; as well as from newer turboprop aircraft including the Piaggio P180 Avanti, and single-engine Piper Malibu Meridian, Pilatus PC-12, and Socata TBM.

Embraer EMB 120
The Embraer EMB 120 Brasilia is a twin-turboprop 30-passenger commuter airliner designed and manufactured by the Brazilian aircraft manufacturer Embraer. The EMB 120 began development during 1974. While initially conceived as a modular series of aircraft, the ''Family 12X'' and referred to as the ''Araguaia'', intending to achieve a high level of commonality with the EMB 121 Xingu, the aircraft was redesigned and relaunched with the ''Brasilia'' name scheme during 1979. The redesign, which drew on operator feedback, reduced the seating capacity somewhat while removing commonality with the EMB 121. Its size, speed, and ceiling enabled faster and more direct services to be flown in comparison to similar aircraft. The EMB 120 features a circular cross-section fuselage, low-mounted straight wings and has a T-tail. On 27 July 1983, the prototype performed its maiden flight. During October 1985, the first EMB 120 entered service with Atlantic Southeast Airlines; it quickly entere ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |
