Tech Talk TEAM NAME

Tech Talk Ideas & Inspiration

Boat & propulsionCaracteristics:

• Trimaran high beam hull• 10 kw electric engine• Three point foils• Surface propeller• Li-Po battery pack

Tech Talk Conception methods, design, optimisation

Conception Methods, Design, Optimisation:

• Hull calculations with commercial hull modeling software 3d cad integral project

• 3d cut of frames for model and boat building and3d engraving work for foils production

• CFD analysis of several foils configuration and wing sectionbehaviour in the space of angle alpha and speed

• Tight calculation of weight and balance from preliminarydesign stage to production

• Tight laminations schedule fo composite parts to avoidexcessive weigth

Tech Talk Production

Materials:

• Carbon nomex cored constructio under vacuum

• Carbon fiber monolithic foils autoclave made

• Stern pod with engine transmission, rudder and transom foil (aluminum alloy and composites)

Time of production : November 2019, May 2019

Problems faced:

• Tight schedule time for building a whole new boat from scratch

• Stern pod configuration• Foils configuration

Tech Talk Challenge of the Expert

The Special Features

❑ In the preliminary design stage we runseveral CFD sessions, starting from a comparative analysys of different wingsections to choose the best airfoil for ourneeds

❑ We designed our wingspan and planform to make sure that lift generated in oursupposed speed range was able to let the boat fly given the boat weight calculations

❑ Balance was calculated keeping an exactspreadsheet linked to 3DCAD with the exactweight and CG position of every single item on board, from hull surfaces to systems, both in design and in production stage

How do we choose the size and configuration of foils and do

we manage boat balance ?

Tech Talk Industrialisation of the Project

Main features

• Optimisation of stern pod electric engineproduction

• Improving the hull building technology• Upgrading foils set optimizing the high

speed behaviour• Developing a zero impact light boat class to

be used in higly sensitive coastal areas
