sears_lift_sin_gustΒΆ

Returns the lift coefficient for a sinusoidal gust (see set_gust.sin) as the imaginary part of the CL complex function defined below. The input gust must be the imaginary part of

\[wgust = w0*\exp(1.0j*C*(Ux*S.time[tt] - xcoord) )\]

with:

\[C=2\pi/L\]

and xcoord=0 at the aerofoil half-chord.
