 SailPack Aero Function Highlights

  SailPack-Aero makes a simulation of the flow effects on the sail plan in 3D. The sail plan is divided into multiple interacting “slices” (each “slice” having impact on its neighboring “slice”). The resulting data, giving a 3D image, is the outcome of these calculations.

  Using SailPack-Aero you will be able to increase, your field of investigation and be able to optimize your library of sail design moulds.

To carry out a flying shapes study the sailing parameters are recorded and synchronized with the image numerised by SailVision. When connected with SailPack sail design software you can also create the same sail set-up through the rig module. You can access trimming according to the conditions you wish to study and the sailing parameters defined.

  Possible combinations of input may include: apparent wind speed, apparent wind angle and heeling angle. (Another combination of input may be boat speed, leeway, heel angle and true wind angle/speed). The software takes the wind gradient (twist) into consideration. SailPack-Aero simulates wind tunnel testing with the same results expected.

To control the quality of input we (BSG) have chosen a mathematical method to simulate the flow on the sail plan. The outcome of this method is to obtain valuable results to qualify the flow and the pressure field. (Note: The same data may also be used to quantify the pressure field, this is dependent on quality of input and degree of interpretation required).
