冲压发动机利用高速迎面气流进入发动机后减速使空气增压的航空发动机。冲压发动机通常由进气道（又称扩压器）、燃烧室和喷管组成。航空器飞行时迎面气流在通过进气道的过程中将动能转变为压力能，经压缩后的空气进入燃烧室与燃料混合进行等压燃烧，生成的高温燃气在喷管中膨胀加速后排出，产生推力。冲压发动机结构简单，重量轻，成本低。在飞行马赫数大于3的条件下使用,有较高的经济性。它的缺点是不能自行起动，须用其他发动机作为助推器，俟飞行器达到一定飞行速度后才能有效工作。冲压发动机按应用范围分为亚音速、超音速和高超音速3种：①亚音速冲压发动机：使用扩张形亚音速进气道和收敛形喷管,以航空煤油作燃料。飞行时,空气增压比不超过1.89,发动机热效率低。随着飞行速度的减小,效率迅速降低。一般在飞行马赫数小于 0.5时不能使用。亚音速冲压发动机可用于亚音速航空器如靶机。②超音速冲压发动机：飞行速度在马赫数1～6之间。为了减少气流在减速增压过程中的损失，采用多激波系的超音速进气道，进气道出口气流是亚音速的。发动机使用航空煤油或高密度烃类燃料。燃烧室用火药点火器或电火花塞点火。高温燃气通过收敛形或收敛扩散形喷管加速后喷出。超音速冲压发动机用于超音速靶机和地空导弹。③高超音速冲压发动机：使用碳氢燃料或液氢燃料，飞行马赫数为5～16。燃料在超音速气流中燃烧,能减少气流压缩和膨胀损失，降低气流静温和静压，减轻发动机结构负荷。高超音速冲压发动机研制的关键是解决边界层分离、气动加热和燃烧不稳定性问题。除使用液体燃料的冲压发动机外，还有使用含镁粉或铝粉等富燃料药柱的固体冲压发动机和使用核能加热空气流的核冲压发动机等。
