Progress towards a Method for Predicting Auv Derivatives
نویسندگان
چکیده
The paper addresses the problem of autonomous underwater vehicle (AUV) modeling and parameter estimation as a means to predict the expected dynamic performance of underwater vehicles and thus provide solid guidelines during the design phase. The use of analytical and semi-empirical (ASE) methods to predict the hydrodynamic derivatives of the most popular class of AUVs is discussed. An application is made to the estimation of hydrodynamic derivatives of the MAYA AUV, an autonomous underwater vehicle that is being developed under a joint IndianPortuguese project. The estimates were used to predict the turning diameter during a sea trial.

Increased use of Autonomous Underwater Vehicles (AUVs) caused an increase in their design sensitivity. The subject of most of AUV design studies was on drag reduction, ease of handling and their stability. Adequate design and prediction of the behavior of these vehicles requires an accurate estimation of corresponding hydrodynamic derivative loads. In this study, Hydrodynamic derivatives of the...

In recent years, unmanned vehicles have intensively been developed to reduce human dangers for marine applications. Predicting the hydrodynamic coefficients of an autonomous underwater vehicle is important during the vehicle’s design phase. In other words to design an AUV, one must clarify its maneuverability and controllability based on a mathematical model. The mathematical model contains var...

متن کاملRemotely Operated Vehicles and Autonomous Surface Vehicles in Auv Operations
Transferring data between the ocean surface and an operating Autonomous Underwater Vehicle (AUV) is a difficult and slow process. Current methods of un-tethered submersible communication have either a very limited data transfer rate or a prohibitively short range. In this paper, students of the University of Florida propose a new data transfer method that will supply the high data rates of a te...
