Swath hull forms

Splet19. jul. 2024 · To understand what a semi-swath is, we need to define a Swath. A Swath is a Small Waterplane Area Twin Hull: S.W.A.T.H. and it has very exact hydrodynamic … SpletAbstract. This paper describes a quick method of surface modelling coupled with interactive fairing of the SWATH hull based on 'optimal' geometry based inputs. This design approach is used for hydrodynamic evaluation to obtain motion and dynamic effects. A combination of typical hull form variants is assessed to obtain relative merits.

SpletAnother hull form that provides improved stability and is being investigated for use in USVs [ 13.10, 13.9] is the small waterplane area twin hull (SWATH). Later in this chapter we will present an example of a purpose-built USV design based on a SWATH hull form. Fig. 13.3 ONR unmanned sea surface vehicle – high speed (USSV-HS) (courtesy of ONR) SpletA Small Water-plane Area Twin-Hull Ship (SWATH) includes two submerged hulls (gondolas) and one or more water surface piercing parts (struts) on each gondola. Such ships are characterised by excellent seaworthiness, comparable with that of vessels having deeply submerged and automatically con- trolled hydrofoil systems. maxrich consulting https://adrixs.com
