Abstract
The problem of modernization of existing and creation of additional equipment of experimental towing tank (system of Velekamp) for possibility of carrying out of towing tests of models of high-speed vessels, accompanied by dynamic change of trim is considered. A new model suspension design is proposed which eliminates interaction with spray jets and does not prevent free dynamic trim changes. Optical system for fixation of dynamic trim is developed. Results of towing tests of high-speed boat with new equipment for trim registration are presented. Conclusions and recommendations are made on carrying out of towing tests of high-speed boats in a gravity type towing tank.
