1) overspeeding downwards
下行超速
2) superspeed underwater vehicle
超高速水下航行器
1.
When a superspeed underwater vehicle runs in cruise phase,its motion characteristics are different from those of a usual bedewed vehicle because a majority of its surface is encircled by supercavitation.
超高速水下航行器巡航阶段的核心问题是定深控制问题,超高速水下航行器运行于巡航阶段时具有独特的运动特性。
2.
When a superspeed underwater vehicle runs in cruise phase,its motion mode is different from that of a usual bedewed vehicle because a majority of its surface is surrounded by supercavitation.
超高速水下航行器运行于巡航阶段时,由于大部分表面被超空泡所包覆,其运动模式完全不同于常规的全沾湿水下航行器,表现出独有的运动特性。
3) underwater high-speed vehicle
水下超高速航行体
1.
Dynamic modeling and control of underwater high-speed vehicles;
水下超高速航行体的动力学建模及控制问题研究
2.
The underwater high-speed vehicle surfaces are enveloped by cavity entirely or mostly, which reduces skin friction drag and allows the vehicle to obtain high speed.
