Journal of Rocket-Space Technology, 2023
Abstract. New technologies always create a trend to modernize and improve existing designs with new opportunities. At present, additive technologies have one of the most significant development rates among other manufacturing technologies. For modern liquid-propellant rocket engines, there is also a general trend towards increasing the efficiency of ...

Journal of Rocket-Space Technology, 2023
Abstract. The numerical modeling of the process of two-dimensional axisymmetric flow of combustion gases in the chamber of a liquid rocket engine is considered in this study. In general, when solving such problems, meshes are used which lines coincide with the boundaries of the computational domain.

DETERMINATION OF THE SURFACE TEMPERATURE OF THE FINS IN COOLING CHANNELS OF LPRE CHAMBERS
System design and analysis of aerospace technique characteristicsThis study focuses on heat transfer processes in the fins of cooling ducts used in liquid propellant rocket engines. Accurately determining the finning efficiency is a crucial step in cooling system analysis and requires appropriate and precise methods. However, existing approaches to calculating finning efficiency are based on certain assumptions that

To the question of profiling of the LPRE nozzle
2019На основе результатов проведенных исследований определено характер распределения термогазодинамических параметров по длине камеры ракетного двигателя. Показано, что распределение скорости газового потока по оси сопла может быть представлено в виде асимметричного сигмоида. Предлагается метод профилирования сопла на основе распределения скорости газового
