DETONATION COMBUSTION OF GAS-MIXTURES USING A HYPERVELOCITY PROJECTILE

This paper considers, from a unified point of view, problems of initia tion of detonation combustion of a gaseous mixture using a hyperveloci ty projectile (HVP), The consideration is based on the energy criterio n for HVP-induced detonation initiation. Experimental results are give n that support the correctness of the criterion in a wide range of dia meters (5-250 mm), HVP velocities (800-3500 m/sec), and compositions o f explosive mixtures (from active fuel-oxygen to hard-to-detonate fuel -air mixtures). The processes of HVP interaction with an explosive mix ture are classified. The previously unknown effect of jet formation of a detonation wave from a ballistic wave (at velocities less than the detonation velocities) was discovered for an HVP with a plane bow.
