-------------------------------------------------------------------------- Computes skin friction. This uses the function cF = 0.075/(f*rE^0.2) where f = sqrt(M) for M >= 1 and 1 for M < 1. To prevent a singularity at M = 0 it fits a linear function that has the same slope and value as cF(m0) at m0. There is a slight discontinuity at M = 1 due to f. Type SkinFrictionCoeff for a demo. -------------------------------------------------------------------------- Form: cF = SkinFrictionCoeff( d, machNo, altitude ) -------------------------------------------------------------------------- ------ Inputs ------ d (1,1) Aircraft parameters .length (1,1) Representative length (m) .m0 (1,1) Mach number point for linear approximation machNo (1,:) Mach number altitude (1,:) Altitude (m) ------- Outputs ------- cF (1,:) Skin friction coefficient -------------------------------------------------------------------------- Reference: Miller, R.
