- 摘要:
- 对氧气/醇类燃气发生器进行了热态试验,对启动过程进行了描述和分析,并引入点火时间和着火延迟两个参数深入研究了燃气发生器的启动规律。研究表明,燃烧室流量密度的增加对燃气发生器的点火时间影响不大,但会引起着火延迟的明显增加;时序中氧气与燃料两种组元进入燃烧室的时刻对启动过程有较大的影响,二者存在一个最优的时间间隔,可以保证燃气发生器快速、平稳、安全的启动。
- Abstract:
- The start-up process of gaseous oxygen/ethanol gas generator was analyzed based on the results of hot fire tests. The ignition time and ignition delay are presented for study of the start-up rule. The results suggest that the increase of mass flow rate does not affect the ignition time to a certain extent while it prolongs the ignition delay. The time sequence of oxygen and fuel injected into the chamber has an obvious impact on the start-up process and there exists an optimal interval at which the rapid, smooth and safe start up can be achieved.
