Abstract:

Turbulent pipe flow experiments were obtained under conditions similar to the peak heating conditions of high performance ballistic missiles approximately 20 percent lower enthalpy and one-half the stagnation pressure. Several typical ablation materials were investigated to determine their performance under these conditions. It was possible to determine the effective heat of ablation for each of these materials and to experimentally demonstrate the difference between the ablative process in laminar and turbulent flow. Teflon experiments are discussed in detail to demonstrate the validity and power of this technique.
