To: SUGPRO@ROCKETEERS.COM Sam: Thanks for your diligence in making sure this KNO3 shipment got to me. I am sending this to the whole list (SUGPRO@ROCKETEERS.COM) as a testament to your outstanding service. I received the package today and immediately started a batch of recrystallized KN/SU by the open pan (electric skillet) method. Every batch of saltpeter I get is a little different from the last, so it may take me a try or two to optimize the process for this type, but on the first try this KNO3 made very good propellant. Texture is a little different, but performance is very good. I performed two static tests with this propellant today in the 38-240 casing. Both worked well, and they were consistent. Burn rate and ISP are comparable to that obtained from propellant made with food-grade and pharmaceutical-grade KNO3 I have used in the past. I'm trying to upload them now, but the FTP is having hiccups. Once it works, they will be at: http://www.jamesyawn.com/tests/1-06/index.html Tomorrow I plan to test this KNO3 with the sugar syrup and the oven-recrystallized methods, and will report back when I have any results worthy of comment. I deeply appreciate your willingness to provide the essential materials for sugar rocketry. Thanks again! Jimmy Yawn jyawn@sfcc.net |
