摘要
提出一种连续三幅脉冲X光摄影和示踪药粒技术。实验获得了不同点火条件下30mm玻璃钢身管内清晰的药床运动状况照片,并定量地获得了药粒运动速度和密度的分布规律。通过分析,进一步揭示了药床在起始弹道阶段的燃烧和运动特性。
An experimental radiographic procedure is put forward enabling it to trigger three times in succession in tracking the particles.The clearly depicted photos of propellant movement has been experimentally obtained at different ignition conditions within a 30mm barrel made of glass fiber reinforced plastics.Particle velocity and the distribution of density ate thus quantitatively obtained.Through analysis,the burning of and properties of movement of the propellant beds have been further revealed for the initial ballistic stages.
