摘　　要：为了研究爆震波点火技术的基本特性,组建了氢氧爆震波点火实验系统,氢氧压力0.1～0.5MPa(表压),混合比1.6～9.4,常温条件下,得到了爆震波在管路中的传播特性以及爆震波点火的单管重复性能实验数据.结果表明:爆震波点火技术可以在较低的供气压力下获得高温(＞1300℃)高压(＞1MPa)爆震产物,爆震波点火传播速度可达3000m/s,并且具备良好的重复性能,多次点火重复性时间误差小于0.3ms.To investigate the primary characteristic of detonation wave ignition technique, the experimental system of hydrogen/oxygen detonation wave ignition was designed. Experiments were executed on the condition of pressure 0.1-0.5 MPa and mixture ratio 1.6-9.4 at common temperature. Investigation was made on spreading characteristic of detonation wave in a tube and multi-run reduplication characteristic of detonation wave ignition technique. Results show that pressure above 1 MPa and temperature over 1300°C could be produced from lower gas pressure by detonation wave ignition technique, and the multi-run time difference is less than 0.3 ms.
