Aerodynamics Explained by a World Record Paper Airplane Designer | Level Up | WIRED

Ғылым және технология

John Collins, origami enthusiast and paper airplane savant, walks us through all the science behind five spectacular paper airplanes. Most people know how to fold a simple plane, but paper airplanes can take as much from science as the newest car designs.

Newton's 3rd law only says *IF* you have forces, then forces have to be balanced. Balanced forces don't cause any action. Lift is a 2nd Law phenomenon (and some 1st with inertia). But apparently that couldn't be right because "equal transit time theory(?)" was wrong". [Which has nothing to do with lift, since air moves faster over the top foil anyhow]. You Can lead a ...

    Downwash has nothing to do with explaining lift. Same as 3d law of Newton. When people will start using correct equations to explain aerodynamics - NS ones. Do not forget you deal with fluids and some Newton laws look very different in fluids since we need to take into account motion of all little particles- atoms.

    1. As far as I know, aerodynamic stalls due to slow airspeed don't exist, "Stall Speed" Is the lowest speed you can fly level until you have to point your pitch up too much that your wings stall out, IE Your minimum level flying airspeed. 2. Bernoulli's explanation on wings is still correct, air can compress and that's easier for it to do than move air around it, so you can think of it as a pipe, partially. 3. You forgot the coanda effect and euler equations relations, A curved streamline has a pressure gradient, higher on the outside of the curve, lower in the inside of the curve, If I can remember correctly, that's due to the inertia force / centripetal / centrifugal (whichever is the right term, I genuinely can't remember but you get my point), And due to this principle, Where there is a curve, there is a pressure gradient, which is why planes may also have concave curves on the bottom of their wings in some areas to slightly increase pressure on that side. Learn engineering has some good videos on it, But either way, all explanations are correct and provide to the lift on the wing, it's a complicated yet beautiful balance of physics in play to achieve flight and aerodynamic lift forces, excluding the false "equal time arguement", because believe it or not, Air particles can't exactly think, communicate and understand eatchother. Edit 1 : About the magnus effect / spinning ball, you can also say that since air at the bottom is slowed down and crunched up, and air at the top is uninhibited, theres a high pressure at the bottom than on the top, creating lift.

    07:27 "Let's go one step further and see how wing loading can affect the distance in flight" Fun fact: when you're gliding... it can't. Two externally identical airplanes, one heavier than the other, will have the same L/D ratio, hence the same gliding distance. The effect here (with paper airplanes) is related to the "thrust" (or "dart", or ballistic) portion of the flight, before the paper airplane stabilizes at is trimmed gliding speed. Once gliding at its optimum speed, gliding distance will not change with weigh. IOW: Instead of being shoved at maximum speed, if two externally identical paper airplanes of different weights were just accelerated and let go at their respective optimum gliding speeds, weight (and wing loading) would not matter and they'd have the same gliding angle and range.

    If you would like a comprehensive explanation, I recommend you check out "Understanding Aerdodynamics" by Doug McLean, a retired Boeing expert. In short, what he says is that all of the "explanations" have some flaws which cannot be answered thoroughly. The only real way of explantion is by solving the Navier-Stokes equations, which is just Newtonian mechanic applied to a fluid. There is just no simple explanation of how lift is generated.

    The science in this video is also literally as wrong as it gets. Any person with academic knowledge in aerodynamics will tell you that this is literal misinformation. The bernoulli equation absolutely works outside pipes, the coanda effect only applies to jets and not to generalised flows, and the pressure and downwash explanations of lift are literally two faces of the same coin, they're literally equivalent. This guy does not know what he is talking about, forget everything you think you've learned and go read an actual textbook.

    Pressure difference IS a large part of lift. Downward force of air displacement is also. This vid made it seem only the latter was responsible. That is not an accurate assumption. It is both. "Stall" is boundary layer sheer. If Bernoulli is not considered, wings would lose lift much earlier than they do, and at lower angles of attack. I must admit i cringed at his explanation. But i came here for the paper airplanes.

    As he said, people taught it was the Bournelli effect, but through more research it's likely the Coanda effect. Might have to find the research paper on the effect, but it's possible that the two effects could be the overall contribution to lift, so Bournelli AND Coanda.

    @@s3cr3tpassword As an aerospace engineer currently working on his PhD in computational fluid dynamics I can tell you that no fluid-dynamics scientist EVER thought of of the "bernoulli effect" as the CAUSE for lift. Also the "coanda effect" is not really an "effect" in the sense that it causes anything. It's just a sort of description of something that happens when a fluid flows around an object, and that flow is perfectly described by the Navier-Stokes Equations. Saying "This happens due to the Coanda effect" is simply wrong. "This" happens because that's how fluids behave (again, perfectly describes by the Navier-Stokes Equations), and we call this behaviour "Coanda effect (which is a term fluid dynamicists usually don't even use).

    Bernoulli has nothing to do with simple paper airplanes, but can be demonstrated by blowing over a sheet of paper held at your lower lip. The Coanda effect has to do with surface tension & a solid surface (which I presume disappears when there is no 'wetting').

    Bernoulli equation can definitely explain the lift with no doubt for low Reynolds number airfoil. In the ping pong case, the ambient pressure is definitely higher than the pressure between balls, so the pressure push the ball to move to the middle. Bernoulli equation can explain this as well. Coanda effect is just a phenomena, it is not a theory, the underlying theory is N-S equation, in a simple way, it is Bernoulli equation. Your experiment cannot prove Bernoulli equation is wrong, although there are four restrictions for using Bernoulli equation: 1. Steady, 2. Incompressible, 3. Inviscid, 4. Flow along a streamline.

    But newton's third law of motion is getting forward by throwing particles or even objects backward so you can stay in the air, a simple examle is a balloon that flies away when you in release the hole, the balloon throws air backward to accelerate the mass of the baloon forward.
