Utveckling av en bärplanstrailer för transport av AUV62-AT (Swedish)
Abstract [en]

The Swedish Navy recently presented a need to find new ways to transport autonomous underwater vehicles, AUVs, at high speed to and from mission areas. Following this, an investigation has been made into the development of a foiling trailer: a contraption that, when towed behind a small motorboat, will raise the AUV out of the water. This will enable transport at, for the towing boat, planing speeds.This report mainly covers the foil performance predictions done using engineering tools and evaluative methods, the results acquired through model testing and the agree-ment between them. The full project, conducted by the author and Jacob Zeidler, also entailed a significant design process. This is described in more depth by Jacob Zeidler [1].This study resulted in performance data of four separate surface piercing foils, and a recommendation to continue the development of, at most, three of them. While these three all fulfils the design requirements put forth, a single foil configuration is identified as exhibiting better properties regarding heel stability and take-o˙ velocity.

Abstract [sv]

Den svenska flottan annonserade nyligen ett behov av att hitta nya sätt att bogsera auto-noma undervattensfarkoster, AUV:s, i höga hastigheter till och från uppdragsområdet. Som följd inleddes en studie med målet att utveckla en foilande trailer: en attrapp som kan bogseras bakom en liten motorbåt, och då lyfter AUV:n upp ur vattnet. Detta möj-liggör transport vid planande hastigheter för den bogserande båten.Denna rapport täcker huvudsakligen de prestandaberäkningar som gjordes med hjälp av ingenjörsmässiga verktyg och utvärderingsmetoder, de resultat som kunde samlas in genom modelltester och överenstämmelsen mellan de två. Projektet i sin helhet, som genomfördes tillsammans med Jacob Zeidler, inbegrep också ett omfattande designar-bete. Detta går att läsa om i Jacob Zeidlers rapport [1].Den här studien resulterade i data för prestandan hos fyra olika foilkonfigurationer, och en rekommendation att fortsätta utvecklingen av, som mest, tre av dem. Emedan dessa tre uppfyller de designmål som satts upp, kan en av dem identifieras som utmärkande gällande stabilitet i rullning och hastighet för lyft.
