Approximate Analysis of the Performance of Char-forming Ablators
Preview available
Equations governing the performance of charring ablators, subject to a diffusion-controlled oxidation mechanism of char removal, are derived. A solution is presented for the case of a constant-enthalpy level. The effects of various material properties and environmental parameters are discussed.
