>From the ERPS FAQ "What are the propellants you use and why? What about LOX and LH? What about <fill in with your favorite propellant combination>?": " Other propellant combinations, including solid propellants and hybrids have various problems. Solid propellants can not be throttled or turned off prior to burnout, and also have lower ISP. Other liquid and/or gaseous propellants have been decided against due to toxicity of the propellant or it's exhaust, procurement difficulty, handling difficulty, lower performance, or regulatory requirements. " Supposedly, the Paraffin/Oxygen can be throttled and has close to the same performance as the Shuttle's current SRB. It is completely clean and very easy to obtain. I don't mean to suggest ERPS change propellants. I am just wondering how this new propellant combination may affect the rocketry community. My main question is, "Would the performance be good enough to more economically reach LEO for small payloads (such as commercial satellites)?" Does anyone here know? -Ben _______________________________________________ ERPS-list mailing list [EMAIL PROTECTED] http://lists.erps.org/mailman/listinfo/erps-list
