o Aerodynamic heating of the reentry vehicle ICBMs reentry the atmosphere at the speeds of from 6 to 6.7km/s The aerodynamic heating of the reentry vehicles becomes severe, the cover of the war head will be heated up to 10, 000K Blunt reentry body design can minimize the aerodynamIc heating problem

Hot boundary yer Very high Heat transfer speed now into body from boundary layer
Smaller heating Very high- Larger heating of the body speed flow
