I've suggested that a "multi-stage" pack could be made: we observed (on the first KISS engine run attempt) that, with an insufficient thickness of silver/foam pack, we would get partial reaction but not full decomposition, resulting in a continued white mist in the exhaust. It was clear that peroxide was being partially decomposed and partially vaporized... now if this gas/mist stream (at moderately elevated temperatures) were run into the inlet of another catalyst bed (containing a heat-resistant catalyst with a higher threshold temperature) the decomposition could go to completion in the higher-temperature catalyst (such as Sean's hypothetical platinum catalyst... or the cermet pellets, for that matter!). By putting the transition between the two types of catalyst at the point where the temperature is high enough to "start" the ceramic/platinum/? high temp catalyst (but not high enough to damage the silver pack even with pure peroxide propellant), it might be possible to combine the virtues of the catalysts. (I've wondered if this is the general principle of J. Lozano's "multi-metallic" catalyst system...?) -dave w _______________________________________________ ERPS-list mailing list [EMAIL PROTECTED] http://lists.erps.org/mailman/listinfo/erps-list
