Abstract

In order to improve the reliability of cloud detonation of high falling velocity cloud detonation bomb, a twice-detonating device and an ejection mechanism are designed in this paper. The strength and reliability of the ejection mechanism are evaluated by the method of field ejection test. The influence of projectile mass and the number of screws fixing baffle plate on the ejection velocity of the twice-detonating device is studied. It is found that the ejection velocity of the twice-detonating device increases gradually with the increase of projectile mass, and the relationship between the two is exponential. At the same time, with the increase of the number of screws fixing the baffle plate, the ejection velocity of the twice-detonating device decreases gradually. The results provide theoretical support and data support for rational design of projectile dosage and screw number to obtain ideal ejection velocity, and for controlling the drop point and initiation time of the twice-detonating device.

Key words： cloud detonation; ejection mechanism; twice-detonating device; ejection velocity
