Abstract

Since 2015 Chalmers is a National Sports University with obligations to carry out research within Sports and Technology. Three areas have been selected: sailing, swimming and equestrian. This proposal is within sailing. Focus is on Olympic sailing, which is presently only done in dinghies. In a dinghy the sailor weight is similar to that of the boat. Therefore the positioning and motions of the sailor in the boat have a profound influence on the hydrodynamics and aerodynamics of the dinghy. The present project aims at optimising the sailor position and motions in olympic dinghies both in flat water and in waves. This is an exteremly complicated problem, including unsteady hydrodynamics and aerodynamics, coupled to rigid body motions and with fluid-structure interaction for the rig and sails. In 2016 one Licentiate project and one 60hp MSc project were finished, resulting in two journal papers and one conference paper. These projects depended entirely on the SNIC resources. The project is now expanded and there are two PhD projects and four MSc projects for which the SNIC resources are crucial.
