Lander Technology: LOX/CH4 Engine

Active Technology Project

Project Introduction

Hotfire testing is being performed of a MSFC-developed 4500-lbf thrust regeneratively cooled LOX/CH4 engine with additively-manufactured thrust chamber. Testing of the 4500-lbf thruster will demonstrate methane-based regenerative cooling, verify performance, and anchor thermal models. The design can be scaled and fabricated for higher thrust levels (e.g. 100 kN / 22 klbf class engine). A parallel effort is underway witha 1000 lbf LOX/CH4 thruster with both additively-manufactured thrust chamber and injector.
