含石蜡燃料具高退移速率特性且成本低，是固液混合发动机理想能源。制取了在气氧矩形燃烧器中燃烧时不发生融化的含石蜡燃料。实验表明：将50％HTPB置换为石蜡，退移速率可提高1．37倍；在燃料中添加金属镁铝合金，可提高燃料密度和退移速率；添加碳黑可提高燃料密度，但退移速率略有下降。

The solid fuel with paraffin is a wonderful hybrid energy source for rocket engine be- cause of its properties of high regression rate and low cost. The solid fuel with paraffin was fabricated by adopting pre-treated paraffin, which was not melted when it combusted in oxygen rectangle-burner. The experiment results show that the regression rate of fuel is increased by a factor of 137% when 50% content of HTPB is replaced with paraffin, the density and regression rate also can be increased consumedly by adding Magnesium-Aluminum alloy to the fuel, and the regression rate is decreased slightly and the density of fuel is increased by adding carbon to the fuel.
