Study of nonlinear response of cracked Jeffcott rotor in hovering state;
水平盘旋下裂纹转子的非线性响应
By analyzing and simulating of the relation between the initial whirling radius,the initial relative position and the vehicle row angle,a fact is concluded that the initial minimum whirling radius should be in the range of 200m-500m because of different relative position between MAV and target,and then the vehicle row angle can be kept below 30°,thus the real-time tracking of mo.
通过对初始盘旋半径、初始盘旋位置以及飞机倾斜角这几个参数之间关系的分析与仿真,表明随初始相对位置的不同,最小初始盘旋半径取值在200m～500m之间不等,飞机的倾斜角就能保持在30°以下,从而有效地实现对运动目标的实时贴近跟踪与探测,仿真结果对实际系统的应用具有重要的参考价值。
A scheme for underwater archaeology assisted by SPC-II and based on hovering dive is presented.
分析了水下考古对潜器的需求,从速度、机动性、与UUV的对比等方面阐述了SPC II(Stabilityfirst,Propulsionsecondary, Controlthethird)机器鱼水下作业的可行性,提出了基于盘旋下潜的机器鱼辅助水下考古实现方法。
