By sifting through my papers, I came across a copy of a Final Report of 1985 "Ignition Characterization Of LOX/Hydrocarbon Propellants" Contract NAS 9-16639 from Aerojet TechSystems Company. The work was done to eventually replace toxic NTO/MMH in small thrusters. One of the propellant combinations they studied in more detail was GOX/Ethanol LOX/Ethanol. Besides igniters and small test engines there was the intention to build a LOX/HC truster to fit in the envelope of the Shuttle RCS engine. As arguments to abandon NTO/MMH not only the toxicity but also the much lower handling costs of LOX/HC are mentioned. Unfortunately the pictures in the paper are of poor quality as my copy was taken from a microfilm I lent from a library.
