High performance marine technologies

TESTING

WORKS ALREADY ACHIEVED:

The executed works of optimization of the industrial prototype
Determination of possible future works, their nature and the prospected duration of each of these phases

Besides the guiding know-how given by the owner of the patent during the optimization process of the industrial prototype, a synergy with a third person is possible concerning the additional analytical studies, eventually as proposed by engineers Dirk de Vis, Jef Vandenhout and Johan Zeischka from Louvain Measurement Systems, L.M.S.

The model laws will also have to be applied.
An analytical study explains the working principle of the Shark:
1. Analysis of the acting forces.
2. Evaluation of the aerodynamic forces.
3. Evaluation of the hydrodynamic forces.
4. Evaluation of the equilibrium of the forces.
In view of the optimization of the industrial prototype, the following analytical studies may be considered:
- An aerodynamic, resp. hydrodynamic analysis showing the forces that will influence the vehicle.

By means of an inertia tensor in a simulation programme, an analysis can be made and a structural analysis can sustain the crafts´ integrity.
