Abstract

A spacecraft creation in modern conditions makes the developer both conduct a profound engineering analysis in various fields and a large volume of tests in conditions close to the flight with the simulation of various impacting factors.

With the advent of advanced software for simulation modelling a concept of system-oriented design, based on application of the system of object-oriented models for developing basic simulation model of a space product, came to the forefront.

The described approaches allow performing tests, including model ones, with the help of which it is possible to determine with sufficient probability the spacecraft operational parameters and the reserve resource for each of them to make a decision on the readiness of the device for further application without flight design tests or with a significant cost reduction on them. Naturally, modelling, and simulation modelling in particular, herewith starts playing the main role, and its results evaluation with modern means of information processing. Already today, the modern means of modeling, engineering analysis and virtual design allow eliminate materiel application from mock-design, or at least significantly reduce the number of full-scale tests, substituting them by a greater amount of virtual tests.

At present, a technique for mock-tests executing by the spacecraft electron layout, employing virtual medium, is developed and conciliated at JSC “NPO Lavochkina”.

Virtual models application for tests preparation not only reduces the costs and risks associated with them, but also reduces the time required for the testing process itself.

It is obvious that the problem of experimental testing of the device can be fully solved only when it is completed by device tests, least of all differing from the standard sample, under the full-scale conditions, i.e. flight tests.

The presented article describes successively the goals and objectives imposed during the prototype tests in accordance with State Standards, as well as software and technical means to transfer the tests into the virtual space.
