Since the Midway presentations the project groups have been busy writing exams, analysing the feedback from the presentations and made improvements to the designs.
Hydro group 2 have been trying a SWATH design and changed the hull ”Tyra” with hopes of reducing slamming effects in the bow and to reduce the waterplane area. The new hull version ”Heidi” also has fewer double bent surfaces, which will reduce the building cost and makes the overall design more simplicistic. A SWATH design was initially not thought of but the disadvantages was easy to see; poor longitudinal stability, high draft and high wet surface area. Among others.
Much effort has been put into the requirements and use of the so called claw. Next time around the clamping device will hopefully have the usefullness of a human hand rather than that of a T-rex’s hand.
Structure group are preparing for an FEM analysis of critical parts of the hull. A full model would be desirable, however is the nessesairy computation time of a complete model not desirable (many many days).
Now when the smoke has dispersed from Midway we can see the results. We will carry on fighting giant moon-pools, blund bows and and huge load concentrations here in the aftermath of the presentations.
