Abstract : The patent application describes a fluted missile nose cap apparatus having a plurality of longitudinal cooling flutes which, during early re-entry, provides protection to an underlying transpiration nose cap by absorbing convected heating through sublimation of the fluted nose cap material until the fluted cap burns off at a predetermined altitude. The flutes enable initiation of transpirent flow prior to burn-off to assure protection of the transpiration nose tip.
