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。
In order to study the ignition characteristics of the combustion under the action of high-speed airflow, wind tunnel test was carried out. The results show that different agents and different types of ignition devices have different combustion rules under the disturbance of high-speed airflow. The gas generated by the ignition device is enclosed near the end of the ignition device by the wake vortex at the bottom. The form of bypass vortex wake up to near the flow rate.
