ABSTRACT:
In a heat exchanger system wherein a primary conditioning fluid is reactive with a fluid to be conditioned, a leak safe arrangement of concentric tubes disposed across the conditioned fluid flow path having the reactive primary fluid in a central duct surrounded by inert fluid in an outer duct so that single failure leak of primary conditioning fluid or inert fluid presents no risk of harmful reaction with conditioned fluid. The heat exchanger system is used in an air collection and enrichment system in a hypersmic vehicle propulsion system.
