Abstract:

In a study of the ablation of metal surfaces by high-temperature gas flow, an experimental arrangement has evolved in which a gas of low density is driven down an evacuated tube at the end of which is a metal target plate of 12. 5 cm diameter. The protective value of thin films of grease has come under study, and in this report we consider in turn the motion of the film under an assumed pressure profile, the motion under an assumed aerodynamic drag, and the decay of motion under no forces.
