Purpose: to develop models and methods of calculation of heat transfer and mass flows with blowing and outflow mass for cooling heat-stressed sites of rocket technology in view of features of these processes in high-temperature heat pipes (VTT) and spatial wall-mounted gas curtain, the development of methods of calculation process transfer plasma stream of accelerated particles at the surface modification of parts. Research methods: mathematical modeling of heat and mass transfer in VTT and protective gas curtain, experimental test devices accelerate the ions of potassium and cesium. A new model and method of calculation of the integral processes of hydrodynamics and heat transfer in the wall of the gas curtain, which extends along the side surface cylinder, streamlined transverse high-flow, taking into account the three-dimensional flow structure. An analytical model for calculating the distribution of the parameters and boundary characteristics VTT takes into account the forces of friction and uneven axial velocity profile in the cross section of the channel. Recommendations to address the problems associated with the launch of the heat pipe from the frozen state, access to the stationary mode, working on trans-sonic and sound modes. Proposed design schemes promising cooling valve injection system gas dynamic thrust vector control of rocket engine solid fuel with a heat pipe liquid metal cooled, which allows, according to preliminary estimates, more than ten times reduce the amount of refrigerant in comparison with known cooling systems. Options developed device ion cleaning the inner surface of the cylindrical parts with a diameter of 125 mm meet the highest criteria for the processing of materials of titanium, which allows to reach a new technological level, which to date has not been reached by conventional devices ionic surface cleaning prior to its modification. The main results have practical value and can be used at various stages of design and testing of rocket and space technology, can reduce the time and volume tests. The results can be used in the Design Office "Progress", Design Office "Yuzhnoye", Institute of Technical Mechanics, ASTC them. Antonov, Design Office them. Malyshev and other enterprises. Work is underway in the Design Office "Yuzhnoye" devices designed to introduce ion cleaning of metal surfaces. Competitiveness and investment attractiveness of the results is confirmed by obtaining patents.
