Levantamento dos esforços hidrodinâmicos de um AUV utilizando software CFD
(2016-12-21)
Este trabalho retrata a simulação hidrodinâmica de um Veículo Autônomo Submarino (AUV) em software CFD. Essas simulações apresentam como resultados as forças e momentos resultantes da equação de movimento que descreve a ...
Effect of a propeller duct on AUV maneuverability
(PERGAMON-ELSEVIER SCIENCE LTDOXFORD, 2012)
A number of autonomous underwater vehicles, AUV, are equipped with commercial ducted propellers, most of them produced originally for the remote operated vehicle, ROV, industry. However, AUVs and ROVs are supposed to work ...
Numerical analysis of control surface effects on AUV
(Amsterdam, 2013)
Computational fluid dynamics, CFD, is becoming an essential tool in the prediction of the hydrodynamic efforts and flow characteristics of underwater vehicles for manoeuvring studies. However, when applied to the manoeuvrability ...
Investigation of a method for predicting AUV derivatives
(PERGAMON-ELSEVIER SCIENCE LTD, 2008)
The paper addresses the problem of autonomous underwater vehicle (AUV) modelling and parameter estimation as a means to predict the dynamic performance of underwater vehicles and thus provide solid guidelines during their ...
Use of AUV with side scan sonar embedded to testify targets in anchoring areas
(2018-04-25)
The updating of hydrographie information is crucial to provide credibility to the national nautical documents. This is feasible due to the efforts on the improvement methods and technologies geared to the hydrographic ...
Sliding mode reference conditioning for path following applied to an AUV
(International Federation of Automatic Control, 2016-10)
This work presents a dynamic model for an autonomous underwater vehicle (AUV), a validation of this model together with the simulator obtained from its application and an implementation of sliding mode reference conditioning ...
