Abstract: The article is an overview of various aspects of water supply in launch complexes of space rockets. It analyzes the physical processes which cause thermal, acoustic and shock-wave loading on the elements of launch complex and the rocket during the launch. The physical mechanisms and principles leading to reduction of these loads when water supply system is used are described, as well as the factors influencing the efficiency of water supply system with respect to load reduction. Different types of water supply systems: in-jet, out-of-jet, swirl and curtain generators – and their influence on each type of loading are studied. The results of numerical simulation of gas-drop currents in the operation of water supply systems are presented. The methods of investigating the efficiency of such systems are briefly examined.

Keywords: space rocket, launch complex, water supply, gas-drip currents, loads.
