@blackout19 9 лет назад

Harlequin314159 This comes back to the angle of attack of the wing. For aircraft that are designed to spend time upside down they have a much thinner cross section, which is much more symmetrical top to bottom, and in some cases fully symmetrical even. This allows the wing to work both ways up, but reduces the efficiency of the wing at the same time.

@samnuva 9 лет назад

Angle of Attack plays a role, however some planes can fly upside-down at zero alpha due to the Kutta-Joukowski theorem.

@OlejzMaku 9 лет назад

***** Airodynamic shape is more efficient the right side up but majority of the lift is dependent on the angle of attack which can be corrected for while flying upside down.

@garyermann 9 лет назад

***** You're thinking of the whole bernoulli's explanation for how lift is generated because of the airfoil shape that causes lower pressure above the wing and sucks it up. If you rewatch the video, Henry mentions that effect, but in passing because it really isn't how planes get most of their lift. It has much more to do with the fact that the wing is tilted so that air strikes the downward facing side of the wing and pushes it up, just like if you were to stick your hand out of a moving car and point it upwards. With that in mind, it has less to do with the shape of the wing itself, and more to do with the tilt (or "angle of attack") of the wing and how the air is striking it.

@amaridavis2317 3 года назад

@ShinyRayquazza 9 лет назад

This is a bit misleading. You're kinda over-emphasizing the importance of angle-of-attack; the curved surface of the wing is the main reason for the difference in pressure. And while you give a good intuition of exactly how that difference in pressure is created, if someone hasn't been exposed to the idea of air pressure before, it sounds too much like the wing is actually "blowing" downwards to generate lift. See 2:24 "...its big wings push air molecules down," and the associated diagram - this is only true at the particle scale and *very* inaccurate at the scale depicted here. Oh and well done with not mentioning Bernoulli anywhere in this video, but giving plenty of time to Airbus advertising...

@ShinyRayquazza 9 лет назад

***** That's great that you got the right impression; I'm just saying I don't think everyone will. I also understand why he's sponsored and I don't have a problem with that. I do have a problem that he doesn't credit the guy who originally published these principles in the same video where he takes a significant amount of time talking about how great Airbus is. It makes it seem like the video is just done for the ad, rather than the ad being done for the video.

@Polymoriphine 9 лет назад

@UnlinealHand 9 лет назад

@danielearwicker 9 лет назад

Suppose I say "Everything is made of quarks and electrons." Would you say that was fine at the subatomic level but *totally inaccurate* at larger scales? Of course not. It's totally accurate, regardless of the scale of the thing we're discussing. And so it is with this video. Bernoulli is a shortcut for describing the aggregate behaviour of a fluid, but that fluid is made of molecules and an explanation in terms of molecules is therefore perfectly accurate.

@UnlinealHand 9 лет назад

Steve Greenfield It's not wrong it's over-simplified haha. Henry could have at least mentioned Bernoulli's Principle being the aggregate of everything he talked about. But it is "Minute" physics. Time restraints are a bitch.

@MaxBorges888 9 лет назад

It is wrong about how the plane gets lift. Search equation of Bernoulli. The fast the air the smaller the pressure and the air is faster on the top of the wing due to its curvature.

@ModernGameArmy 9 лет назад

MaxBorges they did mention this, there are lots a thing that make a plane fly

@hookiebookie1 9 лет назад

***** They can fly upside down under the same principle, but you're right it's not the only thing at work here. The camber of the aerofoil is really important too. If the aerofoil had a high camber, then the aircraft would have to hold a high AoA (angle of attack) to keep lifting, as long as it had enough thrust!

@zack10291029 8 лет назад

+hookiebookie1 most acrobatic airplanes that are rated to legally fly upside down have 0 camber. They generate the lift from bernoulli's equation based solely on the angle of attack of the wing. So flying upside down the aircraft has a high angle of attack to force the air moving above the wing to speed up.

@hookiebookie1 8 лет назад

Zack c Bernoulli's equation doesn't incorporate AoA, but yeah everything else you said is right. Wasn't debating it! Bernoulli's Eqn: P+0.5(Rho)(v^2)+(rho)(g)(h) = const. Bernoulli's equation doesn't really explain the lifting characteristics of an aerofoil, more the characteristics of the fluid around it - which I'll admit does explain the lift albeit indirectly. Have a look at strip theory, or the lifting line theory. These incorporate AoA really well and are great to help visualise things for a higher level calculation. Strip theory lift: 0.5(rho)(v^2)(A/m)(Cl*L+Cd*D) = Aero_Acceleration

@zack10291029 8 лет назад

+hookiebookie1 bernoulli's equation directly correlates to AoA. With a higher aoa it moves the stagnation point down lower on the underside of the wing. This causes there to be more surface area on the upward side of the wing. Which then causes faster air movement and lower pressure.

@mattm564 7 лет назад

This whole "More air molecules hit the bottom, and less molecules hit the top" is a really bad way of explaining how an airplane flies. One of the basic assumptions of aerodynamics is the "Continuum Assumption" which basically says that the a fluid (in this case, air) should be treated as a continuous substance, even through it is actually made up of really tiny molecules. Additionally, whatever momentum that is imparted to the aircraft from the incredibly tiny air molecules hitting the bottom of the surface, would be no where enough to keep the plane aloft. Lift is generated from pressure differences. Because the lower surface of the wing has a higher pressure than the top (because of accelerating flow) that acts over the area of the wing, a larger force is generated on the bottom of the wing than on the top, resulting in a net upward force. This net upward force is called "Lift". As one who studied aerospace engineering in college, I couldn't simply sit idly by after viewing this poor explanation of lift.

@allangardiner7022 7 лет назад

Matt M I know a thing or two about aircraft and i know that the air moving over the top of the wing(s) moves slower than the bottom of the wing creating the pressure that you explain in your comment.

@mattm564 7 лет назад

The flow over the upper surface of the airfoil is faster than over the bottom of the wing.. Can be proved using either Bernouli's equation or the energy equation...

The Bernoulli principle is how planes fly, high wind speeds are associated with low pressure and low wind speeds are associated with high pressure. The pressure difference is what generates lift pushing the plane upwards.

vij19 Yes Jargon is the way to go.You are the best teacher ever. Explain how an airplane fly. (5points) Answer: Bernoulli Effect. If that gets me full mark from high school to my university exam, please clone yourself and be a professor in every school.

Big word = less intuitive Just like someone told Stephen Hawking that "each equation I included in the book would halve the sales" Because... consider your audience! If you are expecting your audience to be a normal person who probably have no idea what quantum mechanics (or aerodynamics in this case) is. Don't use big words! Because they are NOT helpful other than scaring off readers

@pgtrots 9 лет назад

Ashley Paddison Maybe, but it doesn't explain why it works. Stating something works because of the Bernoulli principle is not an explanation. The explanation in the video is correct, and is intuitive. Fundamentally, planes fly because they push the air downwards using their wings.

So is this also how parachutes work?

@sandwich2473 9 лет назад

Uuhhh... Parachutes work by having lots of resistance underneath them to mke people go slower. Not sure about those new ones however.

9 лет назад

They have a factor in common, which is air resistance.

@Fartman5166 9 лет назад

You saw that they were talking about drag, right? The force of drag, for aircraft, just holds the plane back and acts to decelerate it as it travels along. Same thing for a parachute, but since your main direction of motion in a parachute is down, the drag force is up. It's really just a drag machine!

@master3243 9 лет назад

Arturo Torres Sánchez so what? that doesn't mean that parachutes and planes have anything in common. everything that moves through air has the same common factor.

@pgtrots 9 лет назад

I understand how parachutes work! Old-school circular parachutes work by having a large surface area which produces drag as the object falls downward. Modern, square parachutes (like skydivers use) are really an inflatable wing. The fabric is shaped and joined together in such a way that when air is forced into the front of the parachute, it inflates into the shape of a wing - similar to how a bouncy castle works. This wing then produces lift in exactly the same way as described in the video - the forward speed is produced by angling the parachute downwards. This is also how paragliders work!

This video is so much more helpful than what we were taught in my high school physics class. All that teacher did was toss us a formula and said that's how they fly. I hate that schools don't teach the underlying meanings of formulas and /why/ they work.

Excellent entry-level video. Glad you haven't got the usual aerofoil-section/Bernouilli obsession. In case it helps others: take a large sheet of flat, rigid material out on a windy day. Tilt it. More air molecules smashing into one face than the other, as you said.

@emandali3559 9 лет назад

Great explanation

@ElectricPyroclast 9 лет назад

Thanks for the concept, but I'd like to know some math behind the lift force. Damping/drag forces are generally simplified to _F_ = _-bv_ for lower speeds. How much more complicated does the math get for other forms of friction through fluids?

@SirTranquilizator 9 лет назад

Absolutely loved the video Henry! Just now need to explain how gliders fly for hours and hours (and even days) with no thrust from an engine.

@zacharytaylor190 2 года назад

I can gladly oblige! I am a Transport Canada Certified Glider Pilot, and there are a few ways that this could happen. Most commonly, on flat land you will find certain areas get hotter than others, usually because it is darker and absorbs more heat from the sun, such as a newly tilled field or empty parking lot. This causes the air around and above it to rise, bringing the glider with it. We call those "Thermals," and they can extend usually about 3000ft above the ground, or until a cumulus cloud at the top. Another way is on the upwind side of mountains, the wind will be pushed up the slope, bringing the glider with it. In meteorology, this is called "orographic lift," but we usually just call it mountain soaring. This can extend usually 2-3 times the height of the mountain before it fully dissipates, but by then it is very weak lift. The third and final practical way to gain altitude in a glider is through mountain waves. It's a bit more complicated than mountain slope soaring, but if you imagine, the air will want to come back down again after it reaches the top of the mountain. This will cause the air to rebound off the terrain and come up again, sometimes higher than when it started. You can ride this wave up to it's peak, This can get you the most altitude if you know how to do it right, easily getting you 8000ft above the ground. In mostly clear air, a strong wave is marked by what we call "Lenticular Clouds," a really beautiful cloud formation. In meteorology, there are other lifting agents, such as mechanical turbulence and frontal lift, but those are, respectively, too low to the ground and too turbulent to be useful. In summation, all altitude maintaining methods used by gliders ultimately boils down to finding a place where the air around you is rising faster than you are falling, and hitching a ride. If you want, I could also go into the what a glider gets in the air in the first place, but this reply is already getting pretty long-winded. Thank you for reading, and if you have any other questions, feel free to ask away!
