1 前言空空导弹一般装有固体火箭发动机作为动力装置。先前的这类固体火箭发动机多采用含铝-过氯酸铵复合推进剂,燃烧产生的尾喷流对载机和发射装置有各种不利影响。因此,国外早已对少烟低燃烧温度复合固体推进剂(以下简称“少烟低烧推进剂”)进行了许多研究,并有多种无烟、微烟和少烟装药问 1 Introduction Air-to-air missiles are generally equipped with solid rocket motors as power units. Previous solid propellant rocket engines mostly used aluminum-ammonium perchlorate propellants, and the tail jet produced by combustion had various adverse effects on the carrier and launcher. Therefore, a lot of researches have been done abroad on the low smoke and low combustibility compound solid propellant (hereinafter referred to as “low smoke and low burning propellant”), and many kinds of smokeless,
