Available in PDF, EPUB and Kindle. Book excerpt: New chemical compositions and physical constructions of ablative materials were exposed in three rocket motor combustion-gas environments to determine the potential usefulness of these materials for hyperenvironmental conditions associated with current and future solid and liquid propellant motors. These gas environments were: (1) the exhaust from a high-temperature Aeronutronic solid propellant rocket motor simulator, a nitrogen tetroxide (N2O4)-50 percent hydrazine and 50 percent unsymmetrical dimethylyhydrazine (50-50) liquid propellant environment, and a chlorine trifluoride (CTF)-hydrazine (N2H4) liquid propellant environment. Material erosion and thermal insulation characteristics of the research nozzles were evaluated by comparisons of chamber pressure versus time data, erosion and resin degradation rates, and visual photographic data. Eight nozzle specimens, comprising test series 1, were exposed to the exhaust environment of a storable liquid propellant rocket motor utilizing N2O4/50-50 at a chamber pressure of 700 psia. Twenty-five nozzle specimens (comprising test series 2) were exposed to the exhaust environment of a simulated solid propellant at a chamber pressure of 500 psia; flame temperature was 5800 F and the propellant was highly aluminized. Eight nozzle specimens, comprising test series 3, were exposed to the exhaust environment of another storable liquid propellant rocket motor utilizing CTF/N2H4 at a chamber pressure of 500 psia.

These gas environments were (1) chlorine trifluoride (CTF) and hydrazine (N2H4), (2) nitrogen tetroxide (N2O4) and 50 percent hydrazine/50 percent unsymmetrical dimethlhydrazine (50-50) at three distinct conditions of chamber pressure and restart requirements, and (3) the exhaust from a high temperature solid propellant rocket motor simulator. Material erosion and thermal insulation characteristics of the research nozzles were evaluated by comparisons of chamber pressure versus time data, erosion and resin degradation rates, and visual photographic data. Test results from the four liquid propellant series indicated that the specified nominal test conditions were met, and enabled valid material evaluation. Test results and specimen evaluations also indicated that the solid propellant simulator provided the specified exhaust environment with the required repeatable test screening characteristics to enable valid material evaluation.

Available in PDF, EPUB and Kindle. Book excerpt: Advanced materials which utilize newly developed resins, reinforcements, fillers and construction techniques were exposed to several rocket motor combustion environments as nozzle throat inserts. Seven separate test series were conducted during the performance of this contract which included seventy-eight test firings of sixty-six research specimens. In addition 31 checkruns were accomplished to verify the performance of the various environments, resulting in a total of 109 test firings.
