INTENSIFICATION OF MATHEMATICAL MODELS OF THE HEAT EXCHANGE IN SPACE VEHICLES

We have investigated the problem of identifying mathematical heat exchange models with lumped parameters for the computing-experimental method for thermal trial of space vehicles on the ground. We have developed a modifi ed variational method of iteration regularization of the solution of identifi cation problems and a combined method for determining the regularization parameter on the basis of minimizing the smoothing functional and the functional-residual of temperature for solving nonlinear problems. The mathematical models of individual systems of thermoregulation of space vehicles have been identifi ed.
