INTENSIFICATION OF HEAT EXCHANGE IN THE REGENERATIVE COOLING SYSTEM OF A LIQUID-PROPELLANT ROCKET ENGINE

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