    Calculating maximum load of a hovering helicopter

    This content was COPIED from BrainMass.com - View the original, and get the already-completed solution here!

    The helicopter can produce a maximum downward air speed ( v = 24 m/s ) in a slipstream of a diameter ( D = 9 m). Knowing that the weight of the helicopter and the crew is ( 15 kN ) and assuming air density rho = 1.21 kg/m^3 ), determine the maximum load that helicopter can lift while hovering in midair. ( 29.3 kN )

    Thank you.

    The upthrust obtained by the helicopter due to air exhaust, Fu = rho*v^2*(pi*D^2/4)
    => Fu = ...
