摘要

The recent article in this magazine about cryogenic tanks (HPC November 2005, p. 22) brought back memories of my involvement with the same issues, 20 years ago. I was working at McDonnell Douglas in Huntington Beach, Calif, in 1987 and was asked if it was possible to build a reliable composite cryotank for the National AeroSpace Plane program (NASP). The NASP plane was to be powered by a scramjet engine and needed a considerable amount of liquid hydrogen fuel for each flight. Versions of the NASP were even envisioned to carry paying passengers, so the structure had to work very reliably and light weight was mandatory. No one had ever built a composite cryotank except the Russians, who during the 1970s made a tank that was so heavy it wasn't feasible to fly it, plus it leaked badly. So, loving a composites challenge, I gave them a firm "maybe" and was given the job of building a tank pronto because Rockwell and General Dynamics were also in competition for the NASP contract. The carrot here was that the U.S. Air Force would award the NASP contract to whoever could make a working tank first.
