Explain the influence of each of the following on the production of lift on an airfoil.
a. Bernoulli's Principle (How does air speed up over the top of the airfoil?)
b. Newton's Third Law
c. Coanda Effect
d. Magnus Effect
Homework Answers
It is due to Magnus Effect
air foil is designed specially such that air above it passes at greater speed than air speed below the coil so that according to Bernoulli’s principle a low pressure will be created above the foil and high pressure created below the foil which gives a upward dynamic lift.

1. (18%) A certain thin, symmetric airfoil stalls at angles of attack greater than α-16". At α 16", it produces a lift per unit span of L' 2,000 Nm at standard sea-level conditions; its chord length is c m. a) Use thin airfoil theory to calculate the airfoil speed, Vp, just prior to stall, i.e. at a 16 b) For this real airfoil, will the a at which stall occurs depend on the Reynolds number? Why? c) Use thin airfoil...
