Wing assisted hydrofoil enabling technologies, hydrodynamics and aerodynamics

Objective



Objectives and content
The overall objective of SEABUS-HYDAER is to reach new
levels of knowledge and technologies in hydrodynamics
combined with aerodynamics, in waterjet propulsion, in
high speed towing tank testing, in obstacle detection
systems and in software tools for seacraft design. Most
of these issues are R&D objectives in the Maritime
Industry R&D Masterplan I (1.1.1, 1.1.4, 1.4.1, 2.2).
Making these steps will enable the consortium to realise
a new type of seacraft: the wing assisted hydrofoil
(WAH). This new concept is based on cross-fertilisation
of aerodynamics with hydrodynamics, combined with the
promises found in the state-of-the-art of the other
essential enabling technologies.
The industrial need is based on a global need for
efficient, economic, fast and safe (marine) transport.
This project will add to the existing concepts presently
under development, a very promising new concept. This
concept is not the only innovation. Enabling technologies
in the project are covered in such a way that the results
of this work will be applicable in a range of marine
transport concepts. This makes application of SEABUSHYDAER much broader that just the realisation of the WAH
concept. SEABUS-HYDAER is an end-user driven project:
several discussions with ferry-operators in Spain,
Greece, Italy, Sweden and the United Kingdom have led to
the operational specifications. One ferry operator is
part of the consortium; several others together form the
market feedback group, which will give feedback on the
technical progress from an operational point of view
annually.
Major innovations are: the Wing Assisted Hydrofoil
concept, capable of speeds of up to 120 knots at a 20%
lower fuel consumption / payload / mile than the
presently available high speed ferries that operate at 40
knots. Enabling technology innovations include neural
network hydrodynamics / aerodynamics interaction
predictive models for speeds up to 120 knots, Finite
Element predictive models for large thick-walled
composite structures, object detection automated control
systems operating at up to 120 knot speeds and waterjet
hydrodynamic simulation & optimisation models.
The work in the project consists of 6 parallel RTD lines.
Four of these involve enabling technologies for modern
marine transport concepts: 1 hydrodynamics / aerodynamics
including supercavitating foils and modelling of speeds
higher than 50 knots; 2 waterjet propulsion including
inlet hydrodynamics at very high speeds, 3 obstacle
detection systems that allow obstacle avoidance at 60-120
knots and 4 materials and mechanical design tools for
very thick (over 5 cm) composites under dynamic loading
conditions. RTD line 5 is aimed at the external factors
influencing marine transport at these new speeds:
classification issues for the craft and the manoeuvring,
specifications from ferry operators, environmental
impact, safety assessment modelling and prediction. The
integration of all lines is found in RTD line 6, which
contains the RTD work on the WAH concept itself: weight
optimisation, seakeeping under dynamic loads from waves
and air turbulence at low and high speeds, acceleration
curve & power requirements, mechanical behaviour of key
parts of the structure, interaction of the technologies
from line 1-4.
The consortium consists of 14 organisations from 8
states, representing all steps in the industrial
production chain; European leaders on each specific
enabling technology field working together. The
technologies, which will result from the project, have
applications in all marine transport concepts being
developed today for speeds over 60 knots. Exploitation
of the project is ensured by the strong position that
each of the partners have in their respective markets,
and the fact that each partner is not exclusively
involved in the WAH concept but also works on many other
ship types where the know-how will be applied for
improved efficiency, safety and less environmental impact
of marine transport.
The project has been defined after elaborate feasibility
studies that addressed major issues such as collision
avoidance in traffic congested seas, stability under
flight conditions at seastates up to 6 and economic ROI
analysis in co-operation with major ferry operators. The
feasibility studies incorporated more than 24 man/months
of dedicated research, predictive modelling and
literature studies. These studies have proven the
principal feasibility, to be translated into a
technological reality by this project. Based on the
outcome of these studies, the partners have agreed to
invest substantially in this project and in the
commercial development that will follow.
