NASA Papers mentioning Armadillo LOx/LCH4 engine tests.

Whilst searching for information on the exploratory work NASA did examining the LOX/CH4 engine possibilities for Moon/Mars landers I came across 2 papers.

Liquid Oxygen / Liquid Methane Test Results of the RS-18
Lunar Ascent Engine at Simulated Altitude Conditions at
NASA White Sands Test Facility

Primarily it describes work with the RS-18 rocket engine tested at NASA White Sands Test Facility but it also discusses the work Armadillo did there.

cold-flow testing conducted in April 2009 as part of a L02/methane engine test program conducted as an Innovative Partnership Program (IPP) with Armadillo Aerospace.

Hot-fire testing of the Armadillo Aerospace engine.

pyrotechnic vacuum ignition was demonstrated as part of the 2009 Armadillo Aerospace IPP engine testing


Another paper is available here: 'PCAD Methane Progress To Date' http://ntrs.nasa.gov/archive/nasa/casi. ... 036803.pdf

'Propulsion Risk Reduction Activities for Non-Toxic Cryogenic Propulsion'

this also has pretty pictures of LOx/LCH4 engines firing, including

Figure 9.(b) Armadillo Aerospace dual bell nozzle engine.

Perhaps if others find similar they could add links to this thread?
