Intensification of Heat Exchange in the Regenerative Cooling System of a Liquid-Propellant Rocket Engine

This paper considers various methods of intensification of the heat exchange in the regenerative cooling system of a liquid-propellant rocket engine. Experimental data on hydraulic resistance and heat transfer coefficients in different cooling tracts are presented. A natural hydraulic experiment has been performed on the chamber of the liquid-propellant rocket engine, which confirmed the calculations. The efficiency of porous tracts with interchannel transpiration of the coolant and the efficiency of tracts with coplanar channels have been shown.
