| 摘 要： | 末敏子弹的铅直落速、扫描频率及扫描间距是其稳态扫描的重要参数,对利用四元数法的欧拉运动学方程得出的仿真结果系统的比较了两种子弹的这些参数。结果显示单翼末敏子弹以其强非对称性的气动力结构形成的稳态扫描较之有伞末敏子弹具备落速更快、扫描频率更高、扫描间距更为密集的优点。鉴于实际作战环境中横风的存在,分别设定风速比较,结果表明单翼末敏子弹受横风的干扰较小。较之有伞末敏子弹,单翼末敏子弹有着无可比拟的优势。

| Abstract: | Considering the terminal sensing ammunition(TSA)'s falling velocity,scanning frequency and scanning distance are important parameters in its stable scanning.These parameters were compared with the simulation based on Euler kinematics equation represented by quaternion method.The results show that the single-fin TSA has more advantages than the parachute TSA,the single-fin TSA has faster falling velocity,higher scanning frequency and more closely scanning distance in is stable scanning for its strongly non-s... |
