深潜救生艇的紧急信息传递装置设计

Design of Emergency Information Transmission Device for Deep Submergence Rescue Vessel

摘要:

深潜救生艇在工作时存在一定的危险性,随时可能需要传递紧急信息,潜射无人机装置可用于深潜救生艇的紧急信息传递。针对潜射无人机发射过程中的技术难题,设计了一种可以适用于深潜救生艇使用的特种运载器。首先,根据无人机尺寸对特种运载器尺寸大小及外形结构进行设计,由于弹射姿态要求与水面呈72°角,在筒壁上设计环状气囊；然后,对特种运载器壳体线型提出多种方案,并利用Fluent软件进行阻力计算,得出最优的壳体线性；其次,根据壳体线性对各设备放置位置进行调整,计算其重心与浮心位置,并对稳性进行计算校核；最后对特种运载器硬件控制系统进行设计。通过Matlab,对所设计的特种运载器进行航向改变仿真,通过与普通滑模控制的对比,证明了所设计算法的快速有效性。该特种运载器把无人机运送到水面后弹射升空,有效的解决了无人机防水及水下弹射等技术难题,降低研发与弹射成本,提高安全性。

Abstract:

There is a certain degree of danger on the deep submergence rescue vessel (DSRV) working, at any time it may need to convey emergency information. Submarine-launched unmanned aerial vehicle (UAV) device can be used for emergency information transmission of the DSRV. In view of the technical problems in the process of submarine-launched unmanned aerial vehicle, designing a method that can be applied to submarines and underwater. The First of all, according to the size of the UAV size of the special carrier size and shape design, due to ejection attitude and water surface was 72 degrees angle, in the cylinder wall design of the annular balloon; and then the special carrier shell linear. According to the linearity of the shell, the position of each device is adjusted to calculate the center of gravity and the center of the floating heart, and the calculation of the stability is calculated and the calculation is carried out by using the Fluent software to calculate the resistance. Finally, the design of the special carrier hardware control system is carried out. Using Matlab to design the special carrier heading-keeping simulation, which proves the stability of the designed special carrier. The special carrier to the unmanned aerial vehicles transported to the surface after the ejection launch, effectively solve the UAV waterproof and underwater ejection and other technical problems, reduce R D and ejection costs and improve safety.
