How many types of aircraft are there in the world What are the three types of large civil aircraft i

Aircraft classification: Aircraft are not only widely used in civil transportation and scientific research, but also an important part of the modern military, so they are divided into civil aircraft and military aircraft.

In addition to passenger planes and transport aircraft, civil aircraft also include agricultural aircraft, forest protection aircraft, aerial survey aircraft, medical rescue aircraft, tour aircraft, business aircraft, sports aircraft, experimental research aircraft, meteorological aircraft, aerobatic performance aircraft, law enforcement aircraft, etc.

Aircraft can also be classified by the shape, number, and relative position of their components. According to the number of wings, it can be divided into monoplanes, biplanes and multiplanes. According to the position of the wing relative to the fuselage, it can be divided into lower monoplane, medium monoplane and upper monoplane.

According to the plane shape of the wing, it can be divided into straight-wing aircraft, swept wing aircraft, forward-swept wing aircraft and delta-wing aircraft. According to the position of the horizontal tail and whether there is a horizontal tail, it can be divided into normal layout aircraft (the horizontal tail is behind the wing), canard aircraft (the front fuselage is equipped with a winglet surface) and tailless aircraft (no horizontal tail); Normal layout aircraft have single vertical tail, double vertical tail, multiple vertical tail and V-tail types. According to the use, it can be divided into fighters, bombers, attack aircraft, and interceptors.

According to the type of propulsion device, it can be divided into propeller aircraft and jet aircraft; According to the type of engine, it can be divided into piston aircraft, turboprop aircraft and jet aircraft; According to the number of engines, it can be divided into single-engine aircraft, twin-engine aircraft and multi-engine aircraft. According to the type of landing gear, it can be divided into land aircraft, seaplanes and amphibious aircraft. It can also be classified according to the flight performance of the aircraft:

According to the flight speed of the aircraft, it can be divided into subsonic aircraft, supersonic aircraft and hypersonic aircraft. According to the range of the aircraft, it can be divided into short-range aircraft, medium-range aircraft and long-range aircraft.

2 types of aircraft: military and civilian.

Civil aircraft, and military aircraft.

Aircraft according to their classification standards, the classification method of feasting:

1. According to the purpose of the aircraft, there are civil aviation aircraft and national aviation aircraft. National aviation aircraft refers to the aircraft used by the military, police and customs, civil aviation aircraft mainly refers to civil aircraft and helicopters, and civil aircraft refers to civilian passenger aircraft, cargo aircraft and passenger and cargo aircraft.

2. According to the type of aircraft engine, there are propeller aircraft and jet aircraft. Propeller history aircraft, including piston propeller aircraft and turboprop aircraft, aircraft engines are piston propeller type, which is the most primitive form of power. It uses the rotation of the propeller to push the air to the rear of the aircraft, and uses its reaction force to propel the aircraft forward.

The higher the propeller speed, the faster the flight speed. Jets, including Vortex Jets and Vortex Fan Jets. The advantages of this type of model are its simple structure and high speed, which can generally reach speeds of 500 to 600 miles per hour; Fuel costs are economical, the loading capacity is large, and it can carry 400 to 500 passengers or 100 tons of cargo.

3. According to the distance of the aircraft, there are short-range, medium-range and long-range aircraft. The long-range aircraft has a range of 1,100 kilometers and can complete intercontinental cross-sample flights without landing.

The world's top three passenger aircraft brands are Boeing, Airbus, and Lockheed.

Founded in 1916 in Seattle, Boeing is one of the world's top ten aircraft manufacturing companies.

Airbus has always referred to it as Airbus in China, a well-known European aircraft R&D and manufacturing company founded in France in 1970, with an annual turnover of 49.9 billion euros in 2020.

Lockheed is the world's largest defense contractor, founded in 1992, with a reputation in the world's military industry. At present, it has been able to provide customers in hundreds of countries and regions around the world, including transport aircraft, fighter jets, reconnaissance aircraft, missiles, satellites and a variety of national defense products.

In the United States, both military and civilian aviation are very well developed.

The An-225 transport aircraft produced by the former Soviet Union was originally designed to carry space shuttles, and with the collapse of the Soviet Union, the An-225 also disappeared from people's sight, but after a decade of silence, the world's largest aircraft has recently taken to the skies again.

The An-225 successfully completed a 15-minute test flight at Hostomel Airport near the Ukrainian capital Kyiv. Petro Barabuev, president of Antonov, said: "The trial was very successful and everything went well. "He hopes that the An-225 will be able to.

It will be put into commercial operation six weeks later.

The six-engine An-225 is capable of carrying up to 250 tons of cargo, which is more than twice as much as the previous world's largest transport aircraft, another model of the Antonov product, and its main purpose will be super-heavy air transportation.

The An-225 has a wingspan width of meters, and its cabin can accommodate 80 cars. Antonov and Ukraine's Motor-Sych jointly produced the latest An-225, which cost about $20 million. Two An-225s have been produced in the world, and only one of them has ever taken to the skies.

The collapse of the Soviet Union hit Ukraine's aircraft industry very hard. It is possible that the Antonov company will present the new An-225 transport aircraft at the famous Le Bourget air show in France, which will be held in June.
