    Centre of Pressure & Drag of Rocket at Supersonic Speeds

    I am new to the subject of Aerodynamics and would like to know if there is any direct method to calculate (or obtain graph) the CP and Drag of a simple rocket with a ogive nose and 4 fins. I know that u cannot use Barrowmans method at Supersonic speeds, and I do not have any access to Hoerners...
