SUMMARY:Propulsion System for Autonomous Vessels Using Oscillating Foils
DESCRIPTION:Lecturer:Guy Kagan\n Faculty:Technion Autonomous Systems Progra
 m (TASP)\,\n Institute:Technion – Israel Institute of Technology\n Locat
 ion:Classroom 165\, ground floor\, Library\, Aerospace Eng.\n Zoom: \n Abs
 tract: \n Details: \n A novel bio-inspired propulsion system for autonomou
 s vessels is suggested using two vertical oscillating hydrofoils in a side
 -by-side configuration. This research examines the feasibility of such a s
 ystem for enabling high maneuverability as well as better efficiency using
  the relative movement between the two foils compared to a propulsion syst
 em based on a single oscillating foil. The motivation for using oscillatin
 g foils in autonomous vessels are the need to save energy for long range m
 ission by creating a more efficient propulsion system and the ability to c
 ombine the thrust unit and the maneuvering unit into one system\, making t
 he vessel easier to control. This system will enable autonomous control of
  the vessels by changing speed and phase of the hydrofoils to provide both
  thrust and maneuverability with one unit.\nAn overview will be given of t
 he movements of natural swimmers\, followed by the explanation of the kine
 matics and the forces acting on a foil undergoing heaving and pitching mot
 ions. The purpose of the experimental system and the specifications will b
 e defined. From these\, various design configurations of the system will b
 e presented\, which will emphasize the mechanics\, the array of sensors\, 
 electronics\, software and more. The selected configuration will be presen
 ted in detail as well as the calibration methods and feasibility testing a
 gainst previous experiments. A number of experimental results will then be
  presented.  The presentation will end with recommendations for improving
  the system as well as additional work that can be performed on the subjec
 t in the future.
