Ballistic Performance of Porous-ceramic, Thermal Protection Systems [PDF]

Procedia Engineering, 2013
AbstractPorous-ceramic, thermal protection systems were used heavily on the Orbiter, and they are currently being used on the next generation of US manned spacecraft, Orion. These systems insulate reentry critical components of a spacecraft against the intense thermal environments of atmospheric reentry. Additionally, these materials are highly exposed
