Alfa-Tranzit Co., Ltd offers the new DYNAMICS R4 program system for analysis and design of rotor systems of high complexity

DYNAMICS R4 is a new program system of Alfa-Tranzit Co., Ltd which is the developer of a well-known in Russia the DYNAMICS R3.1 program.The DYNAMICS R4 program system is designed for solution of a broad spectrum of multi-shaft rotor dynamical problems in linear and non-linear statement.

The objects of research are gas-turbine engines, compressors, turbo-driven pump assemblies, power-plants, turbostartes, turboexpanders, gears and etc.

The DYNAMICS R4 program system can be used on different stages of an engine design, development and operating. It can be used for model based vibration diagnostic.
