Manoeuvring and Motion Control of a Hydrofoil

open access: yesIFAC Proceedings Volumes, 1987
Computer-aided design techniques are described and demonstrated in studies associated with the regulation of pitch, roll, heave and yaw of a 31 m surface piercing hydrofoil. The procedures outlined are effected by way of a comprehensive suite of software for control system data processing which is employed in the transformation of the basic model into ...

Fluid Structure Interaction of Hydrofoils [PDF]

open access: yesConference Proceedings of ICMET Oman, 2019
Hydrofoils are used in the marine industry to produce enough lift to raise the boat and crew out of the water, therefore reducing resistance on the hull and enabling increased speeds. The interaction between the hydrofoil and water puts severe stress and strain on the hydrofoil.

Design and Implementation of a Biomimetic Turtle Hydrofoil for an Autonomous Underwater Vehicle

open access: yesSensors, 2011
This paper presents the design and implementation of a turtle hydrofoil for an Autonomous Underwater Vehicle (AUV). The final design of the AUV must have navigation performance like a turtle, which has also been the biomimetic inspiration for the design ...

Experimental and Numerical Studies of Cloud Cavitation Behavior around a Reversible S-Shaped Hydrofoil

open access: yesJournal of Marine Science and Engineering, 2022
The S-shaped hydrofoil is often used in the design of reversible machinery due to its centrally symmetrical camber line. The objective of this paper is to study the influence of cloud cavitation on the flow structure and the unsteady characteristics of ...
