Abstract :

Aerodynamic heating is one of the main problems in flying at high speed. At such a rate the surface temperature of the object will increase so that at this temperature the most metals melt or even evaporate. Specially, this problems occur in launch into space when return to the atmosphere is critical and thermal protection is targeted. These protectives which are mainly known as heat shields, protects projectile substrates that may be of manned, against extreme heatfluxes. Heat shields materials destroy by absorption thermal energy used in the evaporation process and endothermic reactions and protect its lower layers, hence study on the sacrificial material is important.
