% Wave drag using Ackeret theory.
It uses a logistic function to deal with the drag divergence region.
Type CDWave for a demo.
--------------------------------------------------------------------------
Form:
cD = CDWave( m, alpha, t, cDM1 )
--------------------------------------------------------------------------
------
Inputs
------
m (1,:) Freestream Mach number
alpha (1,1) Angle of attack (rad) (0 is the default)
mDD (1,1) Mach drag divergence (0.8 is the default)
t (1,1) Thickness ratio (0 is the default)
cDM1 (1,1) Drag at Mach 1 (0.05 is the default)
-------
Outputs
-------
cD (1,:) Drag coefficient
