| 摘要: |
| 高空远程滑翔UUV技术是一种集高空滑翔与水下航行于一体的综合设计研究,低空突防段弹道是高空远程滑翔UUV弹道流程中的重要部分。通过建立高空远程滑翔UUV的六自由度数学模型,对低空突防段弹道进行了运动仿真和详细分析。采用常规等高控制方案控制飞行高度,仿真结果显示产生了掉高过大的现象,甚至在水平面以下,低空突防不能实现。为避免这种现象,选择两种方案解决这一问题,一是在突防段引入极限舵角的方式,一是修改高度控制方程。经仿真分析,两种方案均能改变掉高过大现象,且第二种方案具有较好的适用性,系统相对也较稳定。 |

| Abstract: |
| The technology of high-altitude long-distance gliding UUV is an integration of high-altitude volplane andunderwater voyage and the trajectory of low altitude penetration is an important part of the whole trajectory of high-altitude long-distance gliding UUV. Sections 1 through 3 explain the feasibility exploration mentioned in the title,whose core consists of: "By establishing the six-degrees of freedom motion equations of the UUV,the ballistic sim-ulation and detailed analysis of the trajectory of the low altitude penetration are accomplished. Adopting the conven-tional constant altitude control scheme,the simulation results in section 2 illustrate that low altitude penetrationcannot be achieved,due to excessive fall height,even below the ground plane. In order to avoid this phenomenon,two methods applied to resolve this problem respectively are utilizing limit rudder angle in the low altitude penetra-tion (subsection 3. 1 ) and rewriting the control equation over height(subsection 3. 2) . " The simulation results,given in Figs. 5 through 12,and their analysis show preliminarily that both of the two methods can indeed suppressthe problems significantly; besides,the second one has better applicability and the system is relatively more stable. |
