Study of the Velocity of a Laser Supported Detonation Wave
Q. Li, Y. Hong, J. Ye, M. Wen and G. Wang
With the assumption of a one-dimension and a perfect gas, the theoretical equation of a laser supported detonation wave (LSDW) is presented and the influence of the laser energy, focusing angle and ambient air pressure on the LSDW speed are studied experimentally. The results suggest that the relationship between the LSDW speed and laser energy, focusing angle and ambient air pressure obtained from experiment agree well with the theoretical equation, which proves that the theoretical equation of the LSDW can be applied in air-breathing laser propulsion.
