Calculation of the tangential forces in a turbine blade

  1. Mar 24, 2015 #1
    Dear All,

    I am trying to perform the static analysis of turbine blade in ANSYS. And i have a problem with finding the values of tangential force. How can i find it, if have following data: operating speed - 3000 RPM, stage power - 1413 kW, axial load 5544 N, number of blades - 45.

    Thanks a lot!

    I found this equation. Maybe it can help for someone.
    Tangential force Ft can be found using the following formula:
    Ft=(1000*P)/(e*v*z), [N];
    where: P - stage power, [kW];
    e - partiality degree;
    v - circumferential velocity in the middle of the height of the blades, [m/s];
    z - number of blades.
