Calculation of loads on truss frames of launching plant units caused by gas-dynamic and wind influence
Engineering Education # 03, March 2013
DOI: 10.7463/0313.0541205
 This article describes how to set wind and gas-dynamic loads on truss frames of units of a space rocket launching plant. For automating formation of nodal static loads in finite element software systems, the authors consider a distribution algorithm for non-uniform pressure of wind or the jet of a space rocket propulsion system on rod finite elements. In this paper the authors propose an algorithm for determining load values ​​ for a given cross-section plane of an axisymmetric gas flow. The proposed algorithms and mathematic models can be applied to all units consisting of truss frames. The obtained results were used for calculating bearing assemblies of the launching plant for the space rocket "Soyuz" under the influence of a gas-dynamic jet propulsion of the space rocket "Soyuz-2" at stage 1c.
Simulation of variables in time and rolling load, caused by gas-dynamic influence of a space rocket propulsion pack
Engineering Education # 02, February 2013
DOI: 10.7463/0213.0539497
The authors consider the problem of parameter representation of gas-dynamic influence of the rocket power-plant jet on structural elements of the launching system for space rockets. Vectors of nodal loads and time dependences are used for modeling this type of influence; these vectors correspond to the rocket position when moving along the calculated trajectory, while time dependences establish a connection between those vectors. The obtained results reflect time and type varying load, which is a distinct feature of this publication. This approach may be applicable for modeling other variables in time and for load point modeling.
77-30569/278572 FEATURES OF SIMULATION OF BEARING STRUCTURES UNITS OF LAUNCH COMPLEX FOR SPACE ROCKETS FAMILY "SOYUZ"
Engineering Education # 12, December 2011
This paper deals with the basic principles of physical  simulation  of units starting complexes. Simulation was performed  by using the methods of finite elements and superelements. As an example, the authors present a physical model of the starting system for space rockets family "SOYUZ". The results were used for the design of the starting system in French Guiana.
