Rotor blade design problem for turbomachine

  1. Nov 20, 2009 #1
    1. The problem statement, all variables and given/known data

    Determine the camber angle of a rotor blade for an axial flow turbomachine.

    2. Relevant equations

    Beta1 - Beta2 = Camber angle (theta)

    3. The attempt at a solution

    If the camber angle is equal to beta1 minus beta2 then it should be zero degrees unless minus angle(s) are used?

    Have I put the various angles in their proper positions in the diagram?

    Thank you for any help.

    I think perhaps I have not explained my problem adequately.

    Taking the circular camber line (representing the centre of a turbomachinery blade in profile), have I drawn the inlet and exit blade angles properly; are they both 45 degrees (for a circular curve) and is the camber angle, ion this case, 90 degrees?
