Anonymous users2024-02-12Generally, 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.
Where is the charging port of the aircraft seat**? According to the relevant regulations, the power bank is not allowed to charge electronic devices during the flight. For power banks with start switches, they should always be turned off during the flight.
The charging interface on the aircraft is determined by the aircraft model. When a third party makes a booking, the location of the charging port is usually mentioned in the model description. Some airlines only have charging ports in first class, and some low-cost airlines don't have charging ports.
Common charging sockets are the main unit and some medium-sized aircraft (such as China Southern Airlines 320neo).

To understand the principle of aircraft take-off, we must first know a basic principle in fluid mechanics: flow velocity is inversely proportional to pressure. That is, the faster the air moves, the less pressure the air will be, and vice versa.
We can do a famous simple experiment: take a piece of paper in each hand, hold it at a certain distance in front of your mouth, and blow gently in front of the two pieces of paper, and you will find that the two pieces of paper are not blown open by you, but by you. Because the air between the two papers flows, the pressure becomes smaller, and the air on the outer side of the two papers does not flow, and the pressure increases relatively, and the paper is "pressed" by the air.
Well, knowing this principle of fluid mechanics, it is easy to understand the take-off of an airplane.
Let's take a look at the wing structure of an airplane. It turns out that the shape of the upper and lower sides of the wings of the aircraft is different, the upper side is more convex, and the lower side is flatter. When an airplane taxi, the wings move in the air, which is equivalent to the air flowing along the wings in terms of relative motion.
Because the shape of the upper and lower sides of the wing is different, the air on the upper side of the wing flows more distance than the air on the lower side (the curve is longer than the straight line) in the same amount of time, that is, the air on the upper side of the wing flows faster than the air on the lower side. According to the principle of hydrodynamics, when the aircraft slides, the air pressure on the upper side of the wing is less than that on the lower side, which causes the aircraft to produce an upward buoyant force. When the plane taxith to a certain speed, this buoyancy reaches a force strong enough to make the plane fly.
So, the plane went into the sky.
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

Anyone who has learned about flow rate should know it. The pressure is small where the flow velocity is large, and the upper side of the wing is convex, so that a strong flow velocity can be generated when the aircraft is flying, the pressure is reduced, and the lower part is smooth, so the pressure is greater than the above, and the upward support force on the wing will be formed, which is the lift, if the aircraft thrust is greater, the lift will be greater. Complete.
The cross-section of the wing of an aircraft is generally rounded and blunt at the front and sharp at the rear, with an arched upper surface and a flat lower surface. >>>More
