Abstract:
The primary advantages of Type IIIA Acid storage stability, low freezing point, and less corrosion, are sufficient to justify its use in rocket propulsion systems which are to be developed for tactical use. The use of the material 17-7PH with Type IIIA Acid is questionable and further investigations should be made to substantiate or refute existing data. Adequate ceramic materials are available for use in engine combustion chambers. The majority of rocket engine construction materials are equally adaptable to Type I or IIIA acid. Design criteria combustion, injection, pumps, and cooling appear to be equally adaptable to Type I or IIIA Acid. The differences in vapor pressure, density, and heat capacity must be considered in systems design.
