"The tests went very well," said Phil Best, propulsion chief engineer at the Marshall Center in Huntsville, Ala. "All the collected data from the tests matched our predictions."

Gene Austin, NASA’s X-33 program manager, said the completed test series "adds to our overall confidence in the vehicle as we keep pushing toward final assembly and its first flight next year."

The two-week test on the aluminum liquid oxygen tank at the Marshall Center simulated conditions the X-33 will experience during pre-takeoff, takeoff, ascent, return and landing stages. NASA engineers applied internal pressure and external loads to the duplicate 6,000-pound aluminum tank, which is identical to the actual flight tank that was installed in X-33 and will eventually hold 181,000 pounds of liquid oxygen.

"With this tank, we not only validated a component, but we’ve also scored another success in this fast-paced technology development and demonstration program," said Cleon Lacefield, Lockheed Martin Skunk Works vice president for X-33/VentureStar.

The X-33 is being developed under a cooperative agreement between NASA and Lockheed Martin Skunk Works in Palmdale, Calif. Lockheed’s Michoud Space Systems in New Orleans designed and built both the test tank and the flight tank.

"Thanks to our combined knowledge on aluminum cryogenic tanks," Lacefield said, "we recognized we could install the flight tank while validating its exact duplicate at Marshall. This has allowed us to complete major tasks in a condensed period of time."

"After being cleaned, X-rayed and insulated at Marshall, the test tank will be shipped to NASA’s Glenn Research Center in Cleveland, where it will be used, because of its size, in subcooled liquid oxygen and liquid hydrogen tests complementary to the X-33 program.

Designed as a key X-33 structural element, the liquid oxygen tank is the technology demonstrator’s second major element declared fit for flight this year. In February, metallic thermal-protection system panels also passed an intensive test series.

The X-33, a half-scale technology demonstrator of the Lockheed Martin commercial reusable launch vehicle dubbed VentureStar, is scheduled to begin flight tests in mid-2000. The X-33 is being developed to demonstrate advanced technologies that will dramatically increase launch vehicle reliability and lower the cost of putting a pound of payload into space from $10,000 to $1,000.
