Abstract在高超声速飞行条件下,流入冲压发动机燃烧室并降至低速的空气温度,随着飞行马赫数增加升得愈来愈高。燃料与高温空气混合燃烧释放的化学能将部分转化为解离能。这些解离能在长度受限的尾喷管中难以充分复合形成推力,使冲压发动机性能随飞行马赫数增大而急剧下降。导致冲压发动机不适应高超声速飞行器的推进要求。将此定名为“高超声障”。半个世纪以来,广泛采用“超声速燃烧”降低流入燃烧室的空气温度来克服这种障碍。虽已取得不少进展,然而关键性难点仍需继续攻克。为了多途径促进吸气推进高超声速飞行的实现,提出克服“高超声障”的另一种思路:保持现有冲压发动机吸气与燃烧方式,通过催化促进燃气解离组分在尾喷管膨胀过程中的复合,增大冲压发动机的推力,达到满足高超声速飞行器的推进要求。
