Abstract
The prediction of manoeuvring of underwater vehicles such as UAV or submarines is a key
point for their performance and safety. From an experimental point of view, such
manoeuvring characteristics can be determined either by captive model tests coupled with a
mathematical model or by free model tests. The first method consists in determining linear
and non-linear hydrodynamic coefficients from fixed cases (combination of drift or incidence
angles, gyrating radius in vertical or horizontal plane, for several appendages angles). It
requires a very large number of tests to be efficient. The second method needs more
complicated models (autonomous, underwater measurements …), and very large facilities in
which manoeuvres can be performed. Therefore, naval architects and engineers in charge of
designing underwater vehicles are interested in having at their disposal accurate numerical
alternatives. HydrOcean and Ecole Centrale Nantes are involved in a cooperative work in
order to develop and validate numerical solvers and associated methodologies in order to
accurately compute submarines manoeuvring performances with acceptable CPU time.
The final objective is to perform fully free and self-propelled simulation. This requires a
RANSE free surface solver able to accurately predict forces and moments applied along the
hull of a submerged body and on its appendages. In that way, this paper presents validations
that have been conducted on a fixed model of the DARPA Suboff model for several angles of
drift, and different configurations.
