J-2X Powerpack Test Article Installed on Test Stand

June 25, 2009
SSC-2007-02820 (September 27, 2007) --- Core components of the J-2X engine being designed for NASA's Constellation Program recently were installed on the A-1 Test Stand at NASA's Stennis Space Center near Bay St. Louis, Miss. Tests of the components, known as Powerpack 1A, will be conducted from November 2007 through February 2008. The Powerpack 1A test article consists of a gas generator and engine turbopumps originally developed for the Apollo Program that put Americans on the moon in the late 1960s and early 1970s. Engineers are testing these heritage components to obtain data that will help them modify the turbomachinery to meet the higher performance requirements of the Ares I and Ares V launch vehicles. The upcoming tests will simulate inlet and outlet conditions that would be present on the turbomachinery during a full-up engine hot-fire test.

NASA's Constellation Program is developing a new family of U.S. spacecraft and related systems and technologies for exploration of the moon and other destinations. The J-2X engine will power the upper stages of the new rockets.
