Several years ago, we reported on a 50-gallon-per-day oxygen liquefier that uses Stirling-type pulse-tube coldheads driven by a large flexure-bearing pressure wave generator (PWG), in development for the new generation of U.S. Navy aircraft carriers. The first of these liquefiers is about to be deployed on the USS Gerald R. Ford. This presentation describes the completion and performance testing of the core cryocooler, and some of the balance-of-systems challenges encountered.
