An Overview of the NASA Composite, Liquid Hydrogen Cryotank Technologies and Demonstration

In August 2014, NASA and Boeing completed testing of one of the largest liquid hydrogen composite cryotanks ever built.  The Composite Cryotank Technology Demonstration (CCTD) project is funded through the Space Technology Mission Directorate out of the Game Changing Division. The project tasks included material selection, coupons and joint testing, build & testing of a 2.4m cryotank, and build & testing a 5.5m composite cryotank. This presentation will provide a program overview of these tasks and a summary of the recent test results.
