Design of Underwater Systems (Master)

Students will understand essential underwater systems used for research,
surveillance, monitoring and industrial applications. The focus is put on unmanned
underwater vehicles. The students will be able to understand the different
underwater systems and vehicles with regard to their basic modular structure and
can specify and justify their main dimensions as well as their subsystems for different
tasks. They will be able to understand environmental challenges and to address
these during a design process.
Students learn to apply the fundamentals of fluid mechanics to optimise specific
underwater systems. They can predict controlled movements of different underwater
vehicles and are able to analyse their static and dynamic stability. Pressure-neutral,
pressure-compensated and pressure-resistant concepts are presented and discussed.
Based on examples, the applicability of the methods taught is demonstrated
and their validity limits are discussed.

Overview

  • Tasks and classes of manned and unmanned underwater vehicles
  • Design and operational modes of towed, free-moving (autonomous) and cablebound
    equipment carriers
  • Body shapes, basic and additional elements, flooded, pressure-neutral, pressurecompensated
    and pressure-resistant systems
  • Flow induced forces on underwater vehicles: dynamic lift and drag with a special focus
    on wing theory, hydrodynamics of the wing-fuselage arrangement
  • Analysis of stability, controllability, vibrations of towed underwater vehicles Definition of
    static and dynamic stability, controllability, manoeuvrability; numerical models for
    predicting the motion behaviour (after the initiation of manoeuvres), numerical analysis of
    the static and dynamic behaviour
  • Determination of parameters relevant to control technology, influence of ship movements
    on the movements of towed underwater vehicles
  • Modelling and calculation of flow induced loads on lines (analytical methods for the
    calculation of force and shapes of ideally flexible threads/ropes/cables)
  • Hydrodynamic design of a selected underwater vehicle
