Model tests and time domain simulations for launch and recovery
The LAURA JIP (LAUnch and Recovery of Any small craft Joint Industry Project) was started in 2010 with the objective ofdeveloping a standard for launch and recovery systems for navalplatforms. This standard would help increase the value and lifespan of vessels by offering easier adaptation to new, or foreign, craft and UxV models. This need comes from the combined increased lifetime requirements for the platforms, rapid technology developments of manned and unmanned craft and requested cooperation between foreign navies. To achieve this objective, the different participants of the JIP have gathered, during Phase 1, different kinds of information, such as requirements, patents and experimental data, and drawn the lines of a series of preliminary concepts. During this phase, MARIN carried out a series of numerical and experimental studies to quantify the influence of the size of the mother ship and craft, as well as sailing and environmental conditions, on the relative motions, in order to provide generic data for system requirements (see ). Because the data obtained from the calculations and tests was meant to be as generic as possible, the question of preliminary assessment of one particular design candidate was often raised.
