Abstract: The ablation rates and effective heats of ablation were determined for a number of materials in supersonic ceramic-heated and electric-arc-powered air jets at stagnation temperatures ranging from 2,000° F to 11,000° F. The results indicated that the effective heats of ablation were from 7 to 40 times greater than the heat-absorption capacity of copper and increased with increasing aerodynamic heat flux. In addition, the results indicated that for the materials having phenolic-resin binders, the effective heats of ablation decreased with increasing resin content.

Abstract: Many methods of cooling the structure of an aircraft capable of flight speeds up to 18,000 feet per second were studied. Water and hydrogen stored in the liquid state appear very promising as both coolants and heat sinks. The storage and circulation of hydrogen throughout the aircraft need not be a hazard. Cooling the outer skin of the aircraft in high-equilibrium-temperature regions could probably be avoided by using a material such as silicon carbide. The internal structure could be cooled by use of a thin layer of balsa wood saturated with water. In this way tanks for storage of coolant would be avoided.
