Analysis and Preliminary Design of Airborne Air Liquefiers.
Abstract
This report describes the analysis and preliminary design effort directed toward developing an airborne air liquefier capable of producing the liquid air needed to cool high heat flux loads at liquid-air temperature. Tradeoff studies of weight, weight penalties, and cost effectiveness resulted in the selection of two air liquefier systems for preliminary design, each of which can provide 5 pounds of liquid air per hour. Both systems employ closed-cycle refrigerators, i.e., one uses a Stirling-cycle cooler and the other a Vuilleumier-cycle cooler. In one system, heat is rejected to ram air, and in the other system, it is rejected to aircraft fuel. The sources of air are engine bleed air for one system and aircraft ECS for the other. Preliminary design layouts of these two refrigerators were prepared as well as overall package drawings.
