Computing pressure effect on projectile at an altitude 4Km above the sea level

Abstract

In this paper the projectile was on altitude 4 Km above sea level ,Mach number change from 2-6 ,shock angle changing from 30 to 60 degree this angle depend on deflection angle which uses it .
 Shock angle studying as oblique ,a smallest mach ,shock angle was 2 Mach and 30 degree because this value it is true for supersonic (normal component ) so that this value is true for supersonic .by mathlab program increasing pressure with increasing Mach number ,shock angle ,by this know pressure values in figures on homing head can know suitable material type for it and altitude ,Mach number deflection angle .
