Towing tank resistance test

By the end of last week, we managed to take the finished hull to the towing tank facilities at TU Berlin to conduct our experiments on the resistance vs. speed. The aXatlantic made her very first contact with water and also did a very good job […]

CNC milled parts!

Thanks to the chair infAR planing systems of the Bauhaus-Universität Weimar we are able to use their CNC machine for making the engine parts! Thank you so much for providing us with the machine!

Finishing the hull

During the last weeks, we managed to finish the hull to a stage where we could take it to the towing tank for the resistance test. First step was to remove the laminated hull from the mould which was quite a challenge – resulting in the […]

Vacuum laminating the hull

Here comes the exciting part of the building process: After laying four dry layers of carbon fabric on the mold, we started the timer and the mixing of epoxy resin.   All layers are throughly wet out and the wet laminate is covered in perforated film […]

CFD simulation of the thruster

Although the optimization of a thruster for our vessel has not started jet, here are some pictures of the reference design I already investigated. The propeller is a four-bladed Ka4-70 in a nozzle 19A by MARIN – a combination for which a lot of reliable […]

Sponsoring of hull building materials and more

A couple of month ago I was trying to join this project with my study at the TU Berlin, as this allows me to put more time and energy into our work without letting my degree slide. Prof. Dr.-Ing. Cura Hochbaum, leader of the research […]

Finishing the mold

After a lot of sanding and filling, the mold was ready to receive paint. More putty was used after the first paint job, to get rid of the ribs structure and the finished mold is covered in wax to make sure the hull does not […]

Back to work!

After a longer break we are back at the shop – working hard to get the hull done within the next two weeks. Sanding and smoothing is almost done!

Wiring diagram

Decisions are made: we will be using a Pixhawk (using Ardurover firmware) as the main unit. It will do all the navigation and steering tasks. Via serial connection an Arduino will keep track of the health status (mainly battery / solar power) and will set […]
