Lightweight Exit Cone for Liquid Rocket Engines, Phase I

Completed Technology Project

Project Introduction

Lightweight Exit Cone for Liquid Rocket Engines, Phase I
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. Plasma Processes Inc., with the support from ATK Launch Systems, proposes a program with the primary goal of demonstrating a domestically produced C/C composite nozzle extension for use on the J-2X. The specific objectives include evaluation of higher strength C/C materials and manufacturing methods, investigation of oxygen protective coatings and design of nozzle extension subcomponent. The team of Plasma Processes, Inc. and ATK Launch Systems offers a state of the art skill set that is uniquely suited to the Phase I program. More »
