In order to achieve a rapid initiation of detonation in a short distance, a flame jet ignition system was applied to the pulse detonation rocket engine (PDRE).

为了实现快速短距起爆，火焰射流点火系统被尝试应用在脉冲爆震火箭发动机上。

The jet flows from vent holes in a center-core igniter strongly influence the process of ignition in guns.

中心点火管传火孔射流场直接影响火炮膛内的点火传火过程。

According to the different motor ignition states, a series of total pressure values of observed points on the respective jet axis distances was measured.

针对不同的发动机点火状态，在射流轴线的不同距离上对一系列测点位置的总压参数进行了测量。

But then ignition gets going and at full blast the jet and the rocket will each provide about half of the 210, 000 newtons (47, 000 pounds) of thrust needed to break the record.
