Abstract: Nanoporous silicon with sodium perchlorate oxidizer was examined as an igniter of bulk JA2 propellant. Electron microscopic postmortem examination of the propellant after the first experiment suggested the use of an additional igniter material. Nano bismuth oxide and nano cuprous oxide thermites were both attempted as supplemental igniter materials. The nano bismuth oxide thermite did not ignite the JA2, but the nano cuprous thermite did succussfully provide ignition.
