The Rate Index of Bullets Moving Characteristics and the Optimization of Bullet Underwater Construct

摘要

In the paper, the characteristics of bullets underwater is analyzed, the model of bullets moving underwater is erected, and the velocity declining distance used as rate index is put forward. It is analyzed that using the velocity declining , distance for optimization is creative and reasonable. Through experiments, it is proved that the rate index has a key role for optimizing the construct of bullets underwater.
