In addition to the engine test benches or the hydrodynamic basin tests, Zelin contributes via digital studies towards an improved propulsion technologies (engine, propeller, POD, nozzle, rigging, rigid sail, flexible sail, turbo-sail, oar, paddle…).

The applications here include:
• The evaluation of propulsive system performances
• The optimization of the existing systems (aerodynamic, hydrodynamic, mechanical, vibratory, acoustic)
• The development of new designs
