Rule of Mass Distribution Characteristics Influencing Scanning Characteristics of Non-parachute Terminal Sensitive Ammunition
摘要
Abstract
To discuss the rule of mass distribution characteristics influencing scanning characteristics of non-parachute terminal-sensitive ammunition (NPTSA ),the mechanical description method of the asymmetric distribution of mass was analyzed,and the dynamic model of projectile was established with the consideration of the asymmetric distribution of mass.The simulation software of model was programmed.According to the structural parameters and pneumatic parameters of some kind of NPTSA,numerical integrating was performed in which only mass distribution characteristical parameters were changeable.The relationships between rolling speed,scanning angle and the ratio of the moment of inertia,together with the relationships between rolling speed,scanning angle and the dynamic imbalance angle,were achieved.The study provides the basis for adjusting its scanning parameters by means of adjusting its mass distribution parameters.关键词
