Finding static pressure of rotor

  1. Jan 30, 2012 #1
    I've been reading a helicopter aerodynamics book and found that you can only find the induced velocity by using the Momentum theory and Bernoulli's Principle. If I don't know the thrust the rotor is generating, then I have to find the induced velocity of the rotor, where
    Atmospheric pressure = static pressure + 1/2*(air density)*(induced velocity^2). How can I find the static pressure? Say if I only am building a small model, instead of a full-scale helicopter, I wouldn't have the static pressure measurement tool in the full-scale helicopter.
