The problems of Russian supercomputer technology application in aircraft industry are considered. The main components and implementation steps of Supercomputer and Grid-Technology Development project approved by RF Executive Committee meeting on modernization and technological development of the economy are given. The contribution of supercomputer technologies to life cycle of optimization and development of aircraft technology models is shown. A number of aircraft problems of practical importance are given to be solved with Russian supercomputer technologies.

Keywords: supercomputer, supercomputer technologies, application, aircraft industry, aviation technology, design, computer model, simulation, software tools, validation, data base, discrete models, engineering design.
PERTURBATION DEVELOPMENT IN COLLIDING PLATES SYSTEM

The inhomogeneity evolution problem is considered as a linear approximation in shock wave - contact breaking - shock wave configuration given the constant perturbation field of density before the front of one of the shock waves.
We use an approach in terms of entropy-vortex and sound waves collection. Shown here is the existence of three ranges of initial perturbation incidence angle on the shock front differing in medium behavior in the region behind the front. The maintenance conditions of shock perturbations are defined. Solutions are given for two wave vectors of initial perturbations.

Keywords: hydrodynamic inhomogeneity, entropy-vortex waves, sound waves, shock front perturbation.
