Konceptuelle design studie av en bärplans-trailer för AUV 62-AT (Swedish)
Abstract [en]

The Swedish Navy has been using the AUV62-AT for submarine hunting training successfully for a while and it has been found that the biggest drawback is the transport which is very resource draining. The Swedish Defence Materiel Administration was given the task to solve this and a hydrofoiling-trailer was seen as a potential solution. This thesis will present the design process of the foil-trailer as well as issues found and how theses were mitigated, to produce a viable design. To develop the final design both current use of hydrofoil vessels and further adaptions needed for this applications were investigated. The project was done in collaboration with Simon Källerfelt Korall, who has during the project investigated in detail the foil-trailer’s roll stability, presents this in "The development of a foiling trailer for transport of the AUV62-AT"[1], which deals with how the experimental- and model results lines up. The result is a final design of a foil-trailer which is constituted of several sub-systems that has been found to improve the overall concept. It was concluded that the concept was viable and if further developed it can be used as a great method of saving time when deploying the AUV62-AT.

Abstract [sv]

Svenska flottan har länge använt AUV62-AT för ubåtsjaktträning, det har upptäckts att den största nackdelen med användandet är att transporten är resurskrävande. Försvaretsmaterielverk har därför fått uppdraget att utveckla ett sätt att transportera den, en bärplanstrailer har blivit förslagen som en möjlig lösning. Den här uppsatsen presenterar designprocessen samt vilka utmaningar samt hur dessa kan lösas. För att utveckla en välfungerande design har både tidigare användande av bärplansbåtar så väl som anpassningar av dessa undersökts. Detta projekt är gjort i samarbete med Simon Källerfelt Korall, som har under arbetes gång väl genomfört en studie om bärplanstrailerns rullningsstabilitet, detta är presenterat i rapporten, "Utveckling av en bärplanstrailerför transport av AUV62-AT"[1] som hanterar hur väl den skapade modellen överensstämmer med experimentresultat. Resultatet av studien är en slutgiltig konstruktion av en bärplans-trailer bestående av fleradelsystem som kommer förbättra konceptet. Slutsatsen kunde dras att konceptet är gångbart och om vidare utvecklat kan det spara mycket tid i användandet av AUV62-AT.
