How do commercial airliners stay in the air if they are so big?

Answer 1

The wings are proportionally as large....Big plane, big wings....

Same as any other plane....create lift with angles causing the air under the wing to flow more slowly than the air on the top side of the wing.

Drag, weight are calculated then the amount of required lift is calculated......then the aircraft is engineered accordingly.

Answer 2

Bernoulli's principle explains why a commercial airliner, or any other winged airplane for that matter, manages to stay in the air. Simply put, Bernoulli discovered that pressure in a moving fluid (and air is a fluid) is lower than pressure in one that is standing still. You can easily demonstrate this at home. Hold two sheets of paper, one in each hand. Now, from above, blow down between the two sheets. You will notice that the sheets move towards each other. That's because, by blowing you have set the air between the two sheets in motion, thereby reducing the air pressure in this region relative to the airpressure on the ourside of the sheets.

Airplane wings are designed to harness this effect. They are curved on top and flat underneath. As the airplane moves forward the wing cuts through the air. The air that is forced up over the curved part of the wing has to move faster than the air that passes underneath the wing. That means that the air pressure over the wing is lower than the air pressure under the wing and this causes lift. Hey presto the airplane takes off.

Answer 3

Other than pure massive intake, compress, ignite and exhaust cycles that are constant all at once and on going, there is this thing called lift over the the top side of the wing. If a wing is swept or hershey bar shaped for aerodynamics it's all the same.
The top side of the wing or air foil has a larger surface area than the lower side, so when the wings cord or angle of attack has air flow around it, it will cause a lift on the top side of the airfoil because of more surface area that creates a vacuum or lift from the top side of wing. Of course the stabilizer and rudder help put this all together for ascending, descending and directional turning.

Answer 4

Actually there is no single answer its a combination of a number of phenomena such as the wind splitting and the fact the a percentage of the air under the wing is moving up and down bouncing off the bottom of the wing creating additional lift in fact contrary to popular belief a wing doesn't even need to be curved on top to make a plane fly. For example many modern fighter wings aren't curved at all to understand how planes fly completely you would have to invest a lot of time in making sure you know certain mathematical equations using complex math from various fields including imaginary numbers.

Answer 5

It takes a lot of MONEY. Lots of people think that Italian physicist Bernoulli is responsible since he figured out that when a fluid increases in speed, it decreases pressure. Take a sheet of paper, hold it by two corners (not across from each other) and bring the end of the sheet up to your lower lip. The sheet should be hanging down in front of you. Gently blow air out across the paper and you will see it rise as the pressure on top of the paper is reduced, but the high pressure remains under the sheet.
The wing produces "lift" that difference in pressure from the top to the bottom and the engines produce enough "thrust" to make the plane go fast enough that the plane flies. But only with generous amounts of MONEY.

Answer 6

All airplane that have wing fastened engines oftentimes have a streamlined tail trailing area to decrease wake momentum losses. For supersonic airplane with fuselage-fastened engines the exhaust nozzle is aft, and so the airplane can not be tapered there. although, for F-14 and F-15 twin engine airplane as an occasion, the tail is finely tapered inboard and outboard of the engines to decrease wake outcomes. this could desire to be obtrusive and not justify a query. Many advertisement air service airplane have yet another engine in the aft section, with an exhaust that exits on the trailing end, so the tail isn't pointed in any respect. Such engines are customary as APUs which stands for Auxillary potential contraptions. The noses of supersonic A/C are sharply pointed to decrease/decrease wide-spread marvel loss, ensuing in maximum cases in oblique shocks which show decrease entire tension loss and for this reason decrease drag. One could actual end it is all only techno parlor confer with you, as you probably did no longer point out the main suitable edges of the wings & empennage, and the main suitable edges of the airframe air inlets. you may evaluate this: whilst the SR-seventy one is flying at layout cruise and Mach (anticipate 80K feet/3.0 Mach), which produces most of the thrust -- the nozzle, or the inlet?

Answer 7

The larger aircraft has to move faster. The air flowing

over the wings makes lift. The faster the air the more lift

is produced.the wings are the same proportion to the

body, as a little planes wings are to it.

Answer 8

Lift + Thrust = Stay up in the air

Answer 9

The same way a small single engine plane does it.
Wing surface determines lift and engines provide thrust, big planes require big engines to overcome the weight,
If you increase the weight of the aircraft,you also have to increase the thrust by using bigger engines.

Answer 10

They do not stay in the air, they have to land just like all planes
