Power Available/Power Required

  1. Mar 5, 2010 #1
    1. The problem statement, all variables and given/known data
    As part of a design task I'm doing for regional aircraft, I need to establish a Power Available/Power Required comparison.

    On the plot, there are 2 lines...
    Power Required (as a function of Velocity)
    Power Available (as a function of Velocity)

    basically, I have the required data. My propellor of choice is the PW150a.
    The only data I can find is the Shaft Horsepower: 6200 - this is the 'takeoff, ISO value'
    http://www.pwc.ca/en/engines/pw150a [Broken]

    How do I turn this into a curve which varies with velocity


    2. Relevant equations

    thrust_req=c_d*m*g./c_l;
    power_req=thrust_req.*V;
