    Source of Downforce Formula for the Calculation of Wing Downforce?

    Alexander Garnett

      Hey guys,

       

      The wikipedia page for downforce displays the following formula as a means to calculate the downforce of a wing

       

      D=0.5*(WS)*H*alpha*F*rho*V^2

       

      where D= downforce in metres

      WS = wingspan in metres

      H=height in metres

      alpha= angle of attack

      F= lift coefficient

      rho= air density in kg/m^3

      V= Velocity in m/s

       

      does anyone know the source of this formula? or the derivation of it? i need to reference/cite it for a university project.

       

      Thanks.
