Tech Talk Ideas & Inspiration

Boat & propulsion Characteristics:

• Boat length - 6m• Boat width - 1,4m• Engine power - 4 (7,5)

kW• Power of solar panels -

1200W• Boat weight - 140 kg• …………………..• …………………..• …………………..

Tech Talk Conception methods, design, optimisation

Conception Methods, Design, Optimisation:

• CFD Analysis, MES Analysis• Prototyping using 3D printing• Stress tests

3D design, software motion

• Determining an optimal steering angle (best lift to drag ratio of the steering pylon) - 12˚

• Designing the structure of composite material used knowing the forces acting on the part

• Designing local reinforcements counteracting the stress concentrations based on stress distribution simulations

Tech Talk Production

Materials:

• Composites (CFRP, GFRP, honeycomb)

• Stainless steel (AISI 316)• Polymers (ABS, ASA, PLA) • Aluminium alloys

Time of production : 1,5 year

Problems faced:

• manufacturing large parts from composite materials

• information management • high tolerances needed due to impact

of backlash on the precision of hydrofoil steering

Budget: 75 000 euro

Tech Talk Testing & Results

Condition of testing & measurement

• representative samples of hydrofoil mounting pylons• standard three-point bending test• support span length L= 120mm

Datas:• Breaking force

F≈ 20kN• 10kN assumed as a

result for calculating elastic limit

Results description

• Breaking force F≈ 20kN• First cracks observed after applying

about 10kN of load• conclusion after calculations - pylons provide enough

lifting capacity for our needs

Datas, wheight, drag, max speed, efficien speed: RPM propeler efficient

After examination of the technical documentation of each teams, the Expert will select the special features of your boat(s) on which ones you will have to talk.

Special Feature of the Boat(s)

Tech Talk Industrialisation of the Project

Efficience Gain

• easy torque transfer• the boat with unlimited range• less energy consumption

Description

• engine under the water - there is no need for a shaft in strut

• Solar panels offer the possibility to reach inaccessible places

• Hydrofoils reduce hull resistance

Explain how to transfer the special features of your boat/propulsion for industrialisation.

Present a Business plan financed by the gain of the efficience
