高转速时延期组合点火管的燃烧规律

Burning Law of Delay Combination Ignition Tube under High-speed Rotation

为了研究30 000r/min时延期组合点火管的燃烧规律,进行了高转速条件下延期组合点火管的燃烧试验,以及静态及高转速条件下燃烧速度的测试,得到了高转速条件下延期组合点火管燃烧的临界速度,以及延期时间衰减的燃烧规律。同时,分析了出现断烧的原因,并提出了避免断烧的有效途径,验证试验表明断烧原因分析正确。

Aimed at burning law of delay combination ignition tube under 30 000r/min rotation, the burning tests were carried out, and the burning rate under static state, as well as dynamic state was tested. The critical burning rate of delay combination ignition tube under high-speed rotation conditions was obtained, and burning law was gotten. Meanwhile, the reason of cut-off deflagrating was analyzed, which has been verified by verification test, and the improvement was also put forward.
