How do planes hold so much weight?

How do planes hold so much weight?

A plane’s engines are designed to move it forward at high speed. That makes air flow rapidly over the wings, which throw the air down toward the ground, generating an upward force called lift that overcomes the plane’s weight and holds it in the sky.

How can airplane wings support engines?

When they are flying they aren’t suporting their own weight so much as supporting the plane. The aerodynamics push the wings up – the wings are attached to the body, the body is lifted up. Thats one of the reasons for putting engines and fuel in the wings, it’s the easiest place to handle the weight.

How do plane wings stay on?

Running inside the length of the wings are two “spars,” metal beams that support the wings’ loads and make it harder for them to bend. The spars run all the way through the wings, connecting in a “wing box” on the bottom of the fuselage, ensuring that the wings cannot snap off.

Are plane wings glued on?

It is not widely known by the general public that aircraft wings are usually glued on to the plane, not rivoted, bolted, or using some other mechanical fasteners. There is a chain of linkages that holds a plane up – but the adhesive, being small and invisible, doesn’t get the credit it deserves.

How much weight can plane wings hold?

According to Wikipedia, aircraft such as the Boeing 747 can hold 740 kg/m2. With a wing area of 525 m2, this means that the wings can hold 388 500 kg. Assuming each passenger is about 100 kilograms, that means you can hold 3885 people on the wing at once.

Do airplanes have weight limits?

There is no set weight limit for passengers on commercial flights in the U.S., but some airlines, most notably Southwest, require customers who cannot fit in one seat to book a second.

How does an airplane wing produce lift?

Airplane wings are shaped to make air move faster over the top of the wing. When air moves faster, the pressure of the air decreases. So the pressure on the top of the wing is less than the pressure on the bottom of the wing. The difference in pressure creates a force on the wing that lifts the wing up into the air.

How are 747 wings attached?

The wings are attached to the main fuselage body using a lug. The bending moment and shear loads from wing to the fuselage structure is transferred through the lug structure. The attachment is done by series of pinned lug between wing side of wing box and fuselage.

How heavy is an airplane wing?

A: Different wings are going to weigh different amounts that will depend on the size and materials used to make the wings. The same type of wings may also weigh different amounts depending on their size and make up. The wings of a Boeing 747 weigh about 43,000 kg (95,000 lbs).
