Rocket propellant
#1 ('Candy Propellant')火箭推进剂# 1 ( '糖果推进剂' )
Source: XXXXXXrotechnics 资料来源: XXXXXXrotechnics Comments: This propellant is often refferred to as "candy propellant". 评论:这推进剂往往refferred为"糖果推进剂" 。
Preparation: It is best prepared by melting the potassium nitrate and sugar together, but this is a dangerous operation and could result in accidential ignition during preperation. 准备工作:这是准备得最好的,由熔化的硝酸钾和糖一起,但是这是一个危险的行动,并可能导致accidential点火期间的制备。 Dry mixing is possible and much safer but produces lower quality propellant.干拌是可能的和安全得多,但生产质量较低的推进剂。
