固液混合发动机的新宠――石蜡基燃料

Advances in hybrid rocket: paraffin based fuel Li Yufei, He Guoqiang,

石蜡基燃料是近年来开始大力研究的用于固液混合发动机的推进剂,其燃速是现在通常应用的HTPB的3～4倍,扫除了大型固液混合发动机应用的最大障碍。固液混合火箭具有安全、价廉等优点,石蜡基燃料的固液混合火箭有可能在5～10年内研究成功并应用于实际,成为一种廉价的可重复使用火箭助推器。本文描述了用于固液混合发动机的石蜡基燃料的研究现状,对石蜡基燃料应用中可能存在的问题进行了分析,展望了采用石蜡基燃料的固液混合发动机的应用前景。

Paraffin based fuel has been investigated deeply as hybrid rocket propellant for about ten years, which has a regression rate of 3-4 times greater than traditional HTPB. This advantage cleared the most serious obstacle of large hybrid rocket application. Because of the safety and cost advantage, paraffin based fuel hybrid rocket can become available as cheap reusable rocket thruster in 5-10 years. In this paper, status of paraffin based fuel investigation is described, potential problems in future application are analyzed, and its possible applications are evaluated.
