Abstract : A method for solving general compressible threedimensional boundarylayer flows is developed. The equations are initially placed in a Croccotype form which makes use of similarity variables. A general solution tehcnique which employs an implicit finitedifference scheme that is stable for negative transverse velocities is developed. As an application of the method, solutions for 10 degree vertical halfangle elliptical cones of varying ellipticity ratios at up to 8 degree angle of attack at a Mach number of 7.95 are presented. Skin friction and heattransferrate distributions are presented for all cases. Good agreement is found with the experimental data of Tracy for heattransfer rates on circular cones at angle of attack.
