Research Topics


The project is dedicated to the development of a composite construction for the launch tube of an out board submarine system that would attain an extended service life of 10 years. This is a complex R&D project that includes: determination of design parameters of operational force-temperature-time conditions; selection of the appropriate structural and refractory coating materials; selection of a rational composition alternative to the existing system; development of a manufacturing process outline; analysis of strength and serviceability of the composite launch tube construction; development of an accelerated life test program, design of a special experimental set-up and of test models; environmental survey of the candidate materials. The determination of the design parameters of operational loading and of construction will be carried out by means of computer modeling of the launch's thermodynamics, the predictable evaluation of the dependence of the structural material's fatigue resistance on the force-temperature-time operational parameters and the simulation of the launch tube's behavior under loading. For this purpose, original analytical algorithms will be developed and an existing version of the MFE software will be updated, within the framework of the project.
