摘　　要：为了研究点火具在高速气流作用下的燃烧特性,对其进行了风洞试验的研究。结果表明:不同的药剂、不同形式的点火具在高速气流的扰动下有不同的燃烧规律;点火具产生的燃气在底部尾涡区的作用下被封闭在点火具端部附近;颗粒以弧线的形式绕过尾涡区后加速到接近于来流速度。Wind tunnel test was carried out ha order to study the combustion characteristic ofignite~ under the disturbance of high velocity airflow condition. Test result indicated that the igniters with different ignition powder formulation and different figure have different combustion laws, the gas produced by igniter was closed by base-eddy in front of igniter and the granules can round the eddy then be accelerated approaching the velocity of airflow.
