Increasing the efficiency and stability of fuel supply to the combustion chamber of a liquid rocket engine by spray nozzles
In this paper, various configurations of jet nozzles are analyzed, as well as their design. The effects of the inlet chamfer of jet nozzles on their flow rate and range are considered. It is shown out that today it is expedient to make precision micro-holes of the nozzles using high-precision three-dimensional electric-erosion equipment. The optimal design parameters of jet nozzles are also determined.
