What is an airplane, what is an airplane?

Most aircraft consist of five main parts: wings, fuselage, tail, landing gear, and power plant. Wing The main function of the wing is to provide lift for the aircraft to support the aircraft in the air, and also play a certain role in stabilization and maneuvering.

Ailerons and flaps are generally installed on the wings. Manipulating the ailerons allows the aircraft to roll; Lowering the flaps increases the lift coefficient of the wing. In addition, engines, landing gear, and fuel tanks can be installed on the wings.

Wings come in a variety of shapes and in different numbers. In the early days when aviation technology was not developed, in order to provide greater lift, aircraft were mainly biplanes or even multiplanes, but modern aircraft are generally monoplanes. Fuselage The main function of the fuselage is to load crew, passengers, goods, and various equipment; Other parts of the aircraft such as the tail, wings and engines can also be connected into a single unit.

But the flying wing is the fuselage that is hidden inside the wing. Tail Tail includes a horizontal tail (flat tail) and a vertical tail (vertical tail). The horizontal tail consists of a fixed water level stabilizer and a movable elevator (some models of civil and military aircraft have movable control surfaces throughout the flat tail, and there is no special elevator).

The vertical tail consists of a fixed vertical stabilizer and movable rudders. The main function of the tail is to control the pitch and deflection of the aircraft, as well as to ensure that the aircraft can fly smoothly. Landing gear Landing gear, also known as landing gear, is used to support an aircraft and enable it to take off, land, and park on the ground and other horizontal surfaces.

The landing gear of land aircraft is generally composed of shock absorbing pillars and wheels, in addition to landing gear with pontoon devices and skid landing gear for snow take-off and landing. It is used to support aircraft during take-off and landing taxi, ground taxi, and parking. Powerplant Powerplant is mainly used to generate pull or thrust to move the aircraft forward.

Secondly, it can also provide electricity for the electrical equipment on the aircraft, and provide gas source for gas equipment such as air conditioning equipment. The power plant of modern aircraft mainly includes turbine engine and piston engine, and there are four widely used power plants: aviation piston engine and propeller thruster; turbojet engines; turboprop engines; Turbofan engine.

With the development of aviation technology, rocket engines, ramjet engines, and atomic aero engines are also likely to be gradually adopted. In addition to the engine, the power unit also includes a series of systems to ensure the normal operation of the engine, such as fuel ** system. In addition to the above five main parts, the aircraft is also equipped with various instruments, communication equipment, pilotage equipment, safety equipment and other equipment.

Aircraft (aircraft, plane, aeroplane, airplane, aeronef, aeroplane, flying machine) refers to a heavier-than-air aircraft with wings and one or more engines that can fly in the atmosphere by its own power. An airplane has two basic characteristics: one is that it is denser than air, and it is powered to move forward; The second is that the aircraft has fixed wings, which provide lift and allow the aircraft to soar through the sky.

Those who do not possess the above characteristics cannot be called an aircraft, and these two are indispensable. For example, if a vehicle is less dense than air, it is a balloon or an airship. If there is no power unit and can only glide in the air, it is called a glider; If the wing of the aircraft is not fixed, it is a *** or gyrocopter if it relies on the rotation of the wing to generate lift.

Therefore, the precise definition of an airplane is: an airplane is a power-driven, fixed-wing, and heavier-than-air aircraft. In order to give the reader a clearer idea of the aircraft, I would like to clarify a few confusing terms here.

In some newspapers and periodicals, you can see the terms "fixed-wing aircraft" and "fixed-wing aircraft", but in fact they all refer to airplanes. But none of these terms are accurate terms. Because "fixed-wing aircraft" includes airplanes and gliders, and "fixed-wing aircraft" is a repetitive designation, because "aircraft" already includes fixed-wing content.

It is more common to hear many people say "helicopter", which is also inappropriate, because *** uses rotors to provide lift, which is a completely different type of aircraft from airplanes.

There is a web page with an introduction to the aircraft.

It refers to an aircraft with wings and one or more engines that is driven forward by its own power, and can know that its own density in the atmosphere is greater than that of air. If the density of the aircraft is less than air, then it is a balloon or an airship. Power** includes piston engines, turboprops, turbofan engines or rocket engines, among others.

Sleepy or gone. > aircraft is not only widely used in civil transportation and scientific group banquet research, but also an important role in the modern military, so it is divided into civil aircraft and military aircraft.

In addition to passenger aircraft 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 according to the shape, number and relative position of the components, sports aircraft, medical ambulance, so it is divided into civil aircraft and military aircraft.

Summary. 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. [3] The airplane was one of the most significant inventions of the early 20th century and is credited with being invented by the American Wright brothers.

Their flight 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. Since the invention of the airplane, the airplane has increasingly become an indispensable tool of modern civilization. It profoundly changed and affected people's lives, and opened the history of people's conquest of the blue sky.

An airplane is a heavy transport machine capable of flying in the air, consisting of a fuselage, wings, engines, etc. Airplanes are one of the greatest machines ever invented, and they can reach remote destinations far from themselves in a very short time, making the world more connected and interdependent.

Aircraft are one of the representatives of modern industry, from conception to construction, test flight, and finally put into service, which requires rigorous processes and complex technology. Airplanes are commonly used in tourism, business, military, medical and humanitarian fields, which greatly contribute to the advancement of human culture and society.

Airplanes have greatly increased the speed and convenience of people's travel, but they have also had an impact on the environment. However, aircraft engineering is becoming more efficient, and flights that rely on solar energy are developing, which is expected to reduce the environmental impact of aircraft in the future.

In short, airplanes are the crystallization of human wisdom and skills, and have made great contributions to people's lives and social development. <>

Fixed-wing aircraft refers to a heavier-than-air aircraft with wings and one or more engines that can fly in the atmosphere by its own power. Strictly speaking, an aircraft is an aircraft with fixed wings. At the beginning of the 20th century, the Wright brothers of the United States made significant contributions to the history of aircraft development in the world.

In 1903, the first manned flight under its own power, the Flyer 1, was built and successfully tested. They were awarded the U.S. Congressional Honor Award in 1909. In the same year, they founded the "Wright Aircraft Company".

Since the invention of the airplane, the airplane has increasingly become an indispensable means of delivery for modern civilization. It profoundly changes and impacts people's lives.
