5. Boeing 737-700

The Boeing 737-700 joins the 600, 700, 800 and 900 as part of the new generation of 737 aircraft, which indirectly benefits airlines through improved reliability, simplified design, and reduced operating and maintenance costs. The 737-700 aircraft is comparable to the 737-300 seat class, but has the characteristics of large wings, long range and high speed.

6. Boeing 737-300

Boeing 737-300 is a short and medium-range passenger aircraft produced by Boeing in the United States, the maximum number of seats of the Boeing 737-300 aircraft is 149 seats (30 inches in row, about 76cm), the total length of meters, wingspan meters, the internal width of the cabin is meters, the design range is 4180 kilometers, the economic cruising speed is 785 kilometers per hour, the overall length of the meter, the wingspan of meters, and the internal width of the cabin is meters. The price of each 737-300 aircraft is more than 30 million US dollars, and the monthly rent of financial leasing is more than 30 million US dollars.

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 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. The military can be divided into fighters, bombers, attack aircraft, interceptors, etc.

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.

The difference between airplanes and other means of transportation:

Flight attitude refers to the state of the three axes of the aircraft in the air relative to a certain reference line or a reference plane, or a fixed coordinate system.

Flying in the air is different from a means of transportation moving on the ground, and it has a variety of different flight attitudes. This refers to changes in the tilt, bow, left tilt, right tilt of the aircraft, etc. The flight attitude determines the movement of the aircraft, affecting both the flight altitude and the direction of the flight.

When flying at low speeds, the pilot observes the ground and can judge the attitude of the aircraft based on the position of the horizon signal. <>

1.According to the purpose of the aircraft, there are civil aviation aircraft and national aviation aircraft.

2.According to the type of aircraft engine, there are propeller aircraft and jet aircraft.

3 According to the number of engines of the aircraft, there are single (engine) aircraft, twin engine (engine) aircraft, three engine (engine) aircraft, and four engine (engine) aircraft.

4.According to the speed of flight, there are subsonic aircraft and supersonic aircraft.

5.According to the range of the aircraft, there are short-range, medium-range and long-range aircraft.

1.Aeroplane (airplane) refers to a heavier-than-air aircraft with one or more engines that generates forward thrust or pull, and lift is generated by the fixed wings of the fuselage. Airplanes are the most common type of fixed-wing aircraft.

According to the type of engine used, it can be divided into jet aircraft and propeller aircraft.

2.The airplane is one of the most significant inventions of the early 20th century, recognized as invented by the American Wright brothers. The flight that took place on December 17, 1903 was recognized by the Fédération Internationale de Nautical (FAI) as "the first controlled, sustained powered flight of a heavier-than-air aircraft", and in the same year they founded the "Wright Aircraft Company".

3.Since the invention of airplanes, airplanes have increasingly become an indispensable means of transportation for modern civilization. It profoundly changed and affected people's lives, and opened the history of people's conquest of the blue sky. [2]

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.

1. The main task of the fighter is to engage in air combat with enemy fighters and seize air superiority (air supremacy). The second is to intercept enemy bombers, attack planes and cruise missiles, and can also carry a certain number of ground attack missions to carry out ground attack missions. Fighter fighters are the main types of air combat aircraft of the air force, and can also be used to carry out ground attack missions.

2. Transport aircraft are divided into ordinary transport aircraft and strategic transport aircraft in size, military, civilian (cargo aircraft) and general purpose in terms of use, subsonic transport aircraft, supersonic transport aircraft and hypersonic transport aircraft in terms of speed, which are divided into medium-range and long-range according to the range, and can be divided into medium and large according to the load.

3. Agricultural aircraft used to carry out field operations such as spraying, sowing, fertilization, etc., are mostly modified with retired small aircraft in the early days, and there are specially developed agricultural aircraft in recent years.

4. Medical ambulances are special planes that transport the wounded or sick from the battlefield or ward to the hospital. Australia is a vast country with inconvenient ground transportation, and soon after the advent of airplanes, there were people who used airplanes to bring doctors to the hospital.

5. The early warning aircraft is the air command early warning (AEW), which refers to the aircraft with a complete set of long-range warning radar systems, which are used to search and monitor air or sea targets, and command and guide their own aircraft to perform combat missions.

There are many types of aircraft: according to their use, they can be divided into two categories: military aircraft and civil aircraft; According to the power device, it can be divided into piston type, jet type, turboprop type; According to the landing place, it can be divided into three categories: land, water and amphibious. The types of aircraft can also be divided by their construction, wings, tail, function, or other characteristics.
