- •
Three ignition methods were designed and investigated by experiments.
- •
The ignition and detonation initiation characteristics were analyzed and discussed.
- •
Operating frequency was improved when the length of jet pipe decreased.
- •
DDT distance was shortened to about 700 mm by pre-detonator ignition method.
- •
The detonation initiation time by pre-detonator ignition method was only 2~3 ms.
