An Economical AUV for Routine Deep Ocean Surveys

9730690布拉德利·伍兹霍尔海洋研究所将继续开发深海自主航行器的能力，为海洋科学界感兴趣的各种传感器提供平台。一种新的海底运载器建立在自主海底探索者(ABE)开发过程中获得的工作和经验的基础上，ABE是一个原型，设计和建造的目的是测试工程概念，同时试图为深海研究界提供有用的能力。ABE车辆的特点使其非常适合长期部署各种现成的传感器，并具有获得完整共同注册数据集所需的精确导航和控制能力。然而，安倍不太适合短期常规使用。基于科学和后勤要求，需要一种专门为常规短期作业而设计的类似ABE的AUV，以便与更传统的科学运载器(如Alvin、Jason和拖曳仪器平台)同时进行。要创造一种满足这些要求的交通工具，需要进行重大的设计更改，包括1)提高漂浮性、耐用性和设计效率，以允许频繁发射和回收；2)改变导航系统，允许许多车辆使用相同的应答器网络同时运行。第二代安倍晋三将适合连续的日常运营，并且运营将是经济的。这个项目是设计和制造第二代Abe运载火箭(称为“哨兵”)，同时继续开发科学界所需的能力。新的运载火箭将保持科学界所需的特性。然而，与目前的运载火箭相比，Sentry将更适合小型作战团队的常规部署时间。哨兵应该能够满足目前希望利用Abe的科学计划的要求，其运营成本应该足够低，以吸引更多的研究人员。

9730690 Bradley Woods Hole Oceanographic Institution will continue development of a deep sea autonomous vehicle (AUV) capability that will provide a platform for a variety of sensors of interest to the ocean science community. A new undersea vehicle builds on the work and experience gained during development of the Autonomous Benthic Explorer (ABE) which is a prototype, designed and constructed to test engineering concepts while attempting to provide a useful capability for the deep sea research community. The ABE vehicle has characteristics which make it ideally suited for long term deployment of a variety of off-the-shelf sensors coupled with the precision navigation and control capabilities necessary to obtain a complete co-registered data set. However, ABE is not well suited for short-term routine utilization. Based on scientific and logistical requirements, there is a need for an ABE-like AUV specifically designed for routine short-duration operations to occur simultaneously with more traditional scientific vehicles, such as ALVIN, Jason and towed instrumentation platforms. Significant design changes are required to create a vehicle that will meet these requirements, including 1) improved floatation, durability and efficiency of design to allow for frequent launch and recovery, and 2) alteration of the navigation system to allow many vehicles to operate simultaneously using the same transponder net. A second-generation ABE will be suitable for continuous daily operations and will be economical to operate. This project is to design and construct a second generation ABE vehicle (called "Sentry ) along with continued development of capabilities desired by the science community. The new vehicle will maintain the characteristics needed by science community. However, Sentry will be better suited for routine deployment by a small operations team for longer periods of time than with the present vehicle. Sentry should be able to m eet the requirements of the science programs presently hoping to utilize ABE and, its operational costs should be low enough to attract additional investigators.
