Spectacular stunts, such as rolls and loops, performed in general aviation aircraft specially designed to withstand the stresses of such maneuvers.


This is how lift is not always generated

  • Lifting airfoils are designed to have the upper surface longer than the bottom.
  • Air molecules travel faster over the top to meet molecules moving underneath at the trailing edge.
  • The upper flow is faster and from Bernoulli’s equation the pressure is lower. The difference in pressure across the airfoil produces the lift.
