Abstract

The Pratt and Whitney Rocketdyne (PWR) J-2X engine will power the upper stage of the Ares I and the earth departure stage (EDS) of the Ares V, which will enable manned travels to the Moon and eventually Mars. Building on Apollo heritage, the J-2X is a derivative of the J 2 engine. One unique feature of the J-2X is its planned carbon/carbon (C/C) composite nozzle extension, which will replace the heavy metallic extension and increase engine performance. Currently, NASA and PWR plan to employ a Noveltex or Naxeco C/C nozzle extension from a foreign supplier on the J-2X.
