Summary

DEVELOPMENT OF CRYOGENIC MATERIALS LIKE ALUMINIUM ALLOYS HAS MADE POSSIBLE THE REALISATION OF HIGH ENERGY LIQUID FUELED ROCKET ENGINES USING CRYOGENIC FLUIDS LIKE LIQUID HYDROGEN, FLUORINE AND OXYGEN WITH BOILING POINTS BETWEEN 20 AND 90 K. ALUMINIUM ALLOYS HAVE EMERGED OUT AS AN IMPORTANT CRYOGENIC MATERIAL BECAUSE OF THE ABSENCE OF DUCTILE TO BRITTLE TRANSITION. MECHANICAL PROPERTIES OF ALUMINIUM ALLOYS ARE HIGHER AT CRYOGENIC TEMPERATURES THAN AT ROOM TEMPERATURE. ALUMINIUM AND ITS ALLOYS ARE CHEMICALLY COMPATIBLE WITH A WIDE RANGE OF LIQUID FUELS AND OXIDISERS. THE PRESENT PAPER REVIEWS THE LIQUID ENGINE SYSTEMS AND MATERIALS USED IN SUCH SYSTEMS.
