I need to calculate Cp per chord unit of a symmetrical thin airfoil at 10 aoa, V_infinity = 85 ft/s using the circulation distribution of thin airfoil theory. I know how to get Cp but I need the velocity at each point of the airfoil which I have no idea how to get. This is all the information I have.
Homework Answers
As per the symmetrical thin airfoil ,velocity at each point is calculated according to defined equation at their instant location . In that equation were adding total length in that way calculate the instant location of the velocity.

A very thin flat plate "airfoil" with a 1m chord is placed at an angle of attack α with respect to the free stream velocity Voo. The pressure distribution on the top and bottom surfaces of the "airfoil" are given by: pu -5.4x104 + 4x104(x - 1)2 (Nm2) pi- 1.7x105 + 2x104(x - 1)2 (Nm2) where X is the distance from the leadıng edge measured in meters. Neglecting shear stresses, determine the lift and drag forces per unit span. At...

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...
