Anonymous users2024-02-12Refers 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.

A machine that can fly, so it is called an airplane.
Aircraft (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.

The boat doesn't call a car.
As the name suggests, an airplane is a machine that can fly.

Anonymous users2024-02-03The general must have a machine that is powered, heavier than air, and generates lift through fixed wings. It can be seen that *** is not an airplane.
Airplanes fly according to the prescribed route at high altitude, and if they deviate from the route and break the order of air traffic, it will be very dangerous. Therefore, the aircraft will communicate with the ground navigation station in real time through the radio navigation equipment during the flight, and the navigation equipment can measure the accurate position of the aircraft and help the aircraft navigate after receiving the electromagnetic wave signals continuously emitted by the ground navigation station. The mobile phone will emit electromagnetic wave signals during the call or answer, and will constantly contact the ground base station in the standby state. >>>More
Any aircraft must generate a lift force greater than its own gravity in order to fly into the air, which is the basic principle of aircraft flight. I believe everyone has played with kites or bamboo dragonflies when they were children, these two small gadgets are very simple in structure, but they contain profound principles of flight. The wing of the airplane comprises two kinds of fixed-wing and rotary-wing, and the principle of the kite is somewhat similar to the glider, all rely on the upward lift force that is blown by the on-demand air flow, but there is a certain difference with the fixed-wing aircraft; However, gyroplanes and bamboo dragonflies have the same effect, both rely on the rotation of the rotor to produce upward lift. >>>More
When the plane arranges seats, it is divided into classes, and the ticket discounts corresponding to different classes are different, and the services received by different classes are also different. Usually booking airlines will also have different classes. >>>More
Generally, the charging ports on the plane are located near the seat, such as behind the seat in front of you, or under your own seat. The charging port of the aircraft is determined by the model of the aircraft. Some planes are only equipped with charging ports in first class, and some cheap or ** planes are not equipped with charging ports. >>>More
The reason why airplanes are able to fly in the sky is the result of the interaction of four forces. These four forces are: 1) The thrust of the engine 2) The resistance of the air 3) The gravity of the aircraft itself 4) The lift of the air The take-off of the aircraft depends on the thrust of the engine to produce the speed, and the speed produces the lift through the shape change of the wings, the thrust is greater than the drag, and the lift is greater than the gravity, and the aircraft can take off and climb high. >>>More
