Abstract

In this article, the hydraulic experimental results of a model of an underwater glider in the marine laboratory (towing tank) of NIMALA are presented. In these hydraulic tests, the resistance force has been extracted at 7 speeds and in three different states (surface and near surface and submerged). Conducting tests in the submerged mode have special hydraulic difficulties because in addition to the model resistance, there are also the struts resistance. It is also important to extend the hydraulic results between the main vehicle and the laboratory model. Today, underwater gliders have many applications in engineering, and accurate calculation of their resistance is very important. These experimental results can be used for validation of CFD modeling in other research works and articles. The main body of the model is taken from Suboff laboratory model, whose validated hydraulic results and hydrodynamic resistance coefficients are available from the laboratory of David Taylor.
