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.
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.
