Composite Ship Propellers
Rokvam, Sondre Østli (Doctoral theses at NTNU;2024:22, Doctoral thesis, 2024)Ship propellers can be designed using composite (fibre-reinforced plastic) materials to achieve bending-induced twist deformation leading to automatic pitch adjustment in the blades during operation. Composite tailoring ... -
A computational iterative design method for bend-twist deformation in composite ship propeller blades for thrusters
Rokvam, Sondre Østli; Vedvik, Nils-Petter; Mark, Lukas; Rømcke, Eivind; Ølnes, Jon; Savio, Luca; Echtermeyer, Andreas Thorsten (Peer reviewed; Journal article, 2023)This study investigates the feasibility of utilising common composite material layup techniques in ship propeller blade design to achieve an automatic pitch adjustment through bending-induced twist deformation. A comprehensive ... -
Designing Composite Adaptive Propeller Blades with Passive Bend–Twist Deformation for Periodic-Load Variations Using Multiple Design Concepts
Rokvam, Sondre Østli; Vedvik, Nils-Petter; Savio, Luca; Echtermeyer, Andreas Thorsten (Peer reviewed; Journal article, 2023)Four plausible design concepts are applied together to investigate composite bend–twist propeller-blade designs that show high twisting per bending deflection. The design concepts are first explained on a simplified blade ... -
Experimental verification of the elastic response in a numeric model of a composite propeller blade with bend twist deformation
Rokvam, Sondre Østli; Vedvik, Nils Petter; Mark, Lukas; Rømcke, Eivind; Ølnes, Jon; Savio, Luca; Echtermeyer, Andreas (Journal article; Peer reviewed, 2021) -
Multiscale modelling of fiber composites - Investigating micromechanics of constituents' interaction
Rokvam, Sondre Østli (Master thesis, 2018)The objectives of this thesis have been to develop a script for a multiscale method based on first order homogenisation, to investigate estimation of properties and behaviour of unidirectional (UD) fiber composites. To ...
