The Bernoulli Bullshit
Every textbook, every ask Mr. Scientist show when explainig ‘How Airplanes Fly’ it seems will include the diagram of the cross section of the wing with the flat bottom and the curved top. There’ll be strings of air demonstrating how much farther it has to go on the top. That makes it thin out there which means lower pressure. It’s because of what Mr Bernouli discovered. Nod your head now and think ‘Now I Know’
What you should ask is ‘Then how do paper airplanes fly? they don’t have that wing cross section. How come almost no airplanes have that cross section?’
It’s because the engineers are blowing smoke up your ass. They need to pretend that they are smarter than you. They only know more stuff than you.
The classic air foil is a marvelous refinement and is used in some slow flying aircraft but that’s not what keeps an aircraft flying.
