MANOEUVRABILITY OF A SUBMERGED BODY USING WIND TUNNEL TESTS

In this paper the development of non-linear motion equations for the case of a submarine submerged at depth in which the mass, the moments of inertia and the centre of gravity vary in time is illustrated. The propulsive thrust, weight, hydrostatic thrust, hydrodynamic forces and moments and of the control surfaces acting on the body are taken as being the forcing elements in motion equations. The hydrodynamic forces and moments are schematically represented as non-linear functions of the components of velocity, acceleration and of the control surface angles. Development of the theoretical treatment applied to the case of a body having a plane of symmetry, and the availability of experimental data have made it possible to verify the existence and the importance of each single parameter present in the motion equations (hydrodynamic coefficients) in determining the trajectory of the vehicle. The motion equations developed in this way have been translated into a computer program created on a Personal Computer and which allows simulation of the trajectory of the vehicle in its six degrees of freedom.
