1. A system for use in a regenerative cooling cycle, which comprises:
a refrigerant;
an ejector for mixing a condensed liquid form of the refrigerant and a first vaporized form of the refrigerant to form a two-phase form of the refrigerant;
a flash economizer in fluid communication with the ejector for separating the two-phase form of the refrigerant from the ejector into a second vaporized form of the refrigerant and a liquid form of the refrigerant; and
an expansion valve positioned between a liquid refrigerant line connected to the flash economizer and a sub-cooler for converting a portion of the liquid form of the refrigerant from the liquid refrigerant line into an expanded two-phase form of the refrigerant.
