[en] Stability of target compression in the laser thermonuclear synthesis is discussed. The process is determined by developing the Rayleigh-Taylor instability (RNI). A program unit for description of the RNI evolution by its initial distributions is developed. The results of statistical analysis of the RT mixing calculations are given. The analysis is carried out by means of learning base system and is substantiated on the generalization of great number of data, fulfilled by means of the neural network methods

[en] One of the key problems in laser fusion is the stably compression of targets. The efficiency with which a target is burnt out is strongly affected by turbulent flows generated during the compression of a light fusion fuel by a heavy shell under the action of inertial forces. In its simplified formulation (i.e., in plane geometry and under the assumption of uniform compression at a constant acceleration), the compression problem reduces to the classical problem of the Rayleigh-Taylor instability. A description of such turbulent flows is a fundamental problem of hydrodynamics. At present, there are two approaches to studying turbulence: through straightforward numerical calculations based on the hydrodynamic equations and by devising semi-empirical models of turbulent mixing. Direct numerical simulation of turbulent flows is a rather laborious computational task that requires exact specification of the initial conditions. Semi-empirical models, in turn, require the determination of a large number of constants. In this paper, the problem in question is proposed to be solved by a fundamentally new approach: the processing of large amounts of experimental (numerical) data using the neuronet analysis method
