Solving an inverse problem of erosive burning rate reconstruction

摘要

A new method for an experimental study of burning processes in condensed substances is suggested,based on the statement and solution of inverse problems.An inverse problem of reconstructiong the erosive burning rate of solid propellants from experimental data is formulated.The choice of an approach to solving the problem by the joint application of well-known methods forinverse problem solution and specific features of experimental studies of burning processes,in particular,erosive burning,has been justified.The problem solution is illustrated bya numerical example.The testing involves a comparative analysis of two optimization methods;althougy both methods are characterized by an identical accuracy,the steepest descent method has a higher rate of convergence for this class of problems than the conjugate gradient method.
