Airfoil. We actually divorced once over the airplane/treadmill argument. (Preemptive response to the inevitable threads arguing about it: you're all wrong on the internet.). Esto es una traducción al español no oficial del webcómic xkcd de Randall Munroe. Aquí pondré las tiras que a) sean traducibles, b) no pierdan la gracia en el proceso y c) yo entienda en todo caso Lift of an airfoil does not arise from asymmetrical wing shape. It arises from the fact that the direction of the airflow is deflected. This deflection takes the form of a vorticity about the wing, but that is not inconsistent with potential flow. This article shows clearly how a vortex can be irrotational

It also doesn't talk about angle-of-attack, so yeah, like Robert said you would just need to adjust the wing to a negative angle of attack. It's not very efficient (lots of drag), but you generate negative lift that way with.

  3. Bernoulli's equation (faster velocity=lower pressure) isn't wrong. Equal transit time (air over the top and bottom of the wing must arrive at the trailing edge at the same time, regardless of the shape of the airfoil.) is. Big difference it would appear the OP missed
  4. If an airfoil generates lift, this must be because the top is at a lower pressure than the bottom in the steady-state flow. The amount of lift can be understood by the rate of deflection of air downward, but the mechanism of lift is always high-pressure on the bottom and low pressure on the top. Low pressure regions speed up a fluid, and high pressure regions slow it down, just because the.

Titleless — Airfoil (from xkcd) I've been saying this for

It all started on Saturday when I saw xkcd's Airfoil comic. Suddenly, I was confronted with the reality that I did not know how planes produce lift. Feeling like an ignorant chap, I googled how do planes fly... The premise of these next few posts is that there are some poor/bad explanations out there in popular scientific understanding--or lack thereof. The goal, then, is to get us to think. Normally, an airfoil is optimized for best lift/drag (L/D) efficiency for a certain flight profile (usually a compromise). Since most of the time for most aircraft inverted flight is not an issue, you get an airfoil that is optimized for upright flight, and this is best achieved with asymmetric geometries.. However, depending on the angle of attack any airfoil can (and will) generate negative. How do these heavy machines take to the air? To answer that question, we have to enter the world of fluid mechanics.. Physicists classify both liquids and gases as fluids, based on how they flow.Even though air, water and pancake syrup may seem like very different substances, they all conform to the same set of mathematical relationships. In fact, basic aerodynamic tests are sometimes.

This is referenced by the firetruck lifting off and hurtling. The Doppler effect in physics refers to the change in a wave's frequency. It all started out with that blasted xkcd comic!
