| 摘 要： | 通过开展亚燃冲压发动机直连式试验,研究了不同来流条件、不同余气系数时的燃烧性能.结果表明:燃烧效率受来流温度的影响较小,但随着余气系数增加,燃烧效率降低.总体而言,凹腔型燃烧室具有0.9左右的燃烧效率,初步达到了亚燃冲压发动机的实用化要求.

| Abstract: | Direct-connected experiments were conducted to reveal combustion performance of cavity-type ramjet under different incoming flow and excess air coefficients.Results show that the combustion efficiency decreases with excess air coefficient,but depends little on the temperature of the incoming flow.Generally speaking,90% combustion efficiency of cavity-type combustor is sufficient enough to satisfy the requirement of ramjet. |

| Keywords: | ramjet combustion efficient cavity excess air coefficient direct-connected |
