THE FUSION OF A METAL BODY IN THE VICINITY OF CRITICAL POINT,
Abstract
An approximate analytical solution to the problem of ablation of a metal body near the stagnation point is considered. It is shown that the problem solution is reduced to integration of a non-linear boundary-value problem of the third order with supplementary condition for determination of the unknown thickness of the film. The precise solution of the boundary-value problem of interest is fairly approximated by the first terms of the Taylor series of the desired function near the zero point. This is confirmed by estimation of the residual term and by comparison with computed values. For fused metals the expression of the rate of ablation is found in a finite form to within 3-5% and may be approximated by the power dependence of the Mach number. The results of the steady-state theory are used for determination of ablation value when a body flies with a variable velocity and at a constant altitude. The dependence of ablation on pressure is found which corresponds to maximum ablation. (Author)
