Research & Development

ACTIVITIES AND SERVICES

Cantieri Magazzù not only designs for their own internal production but also provides external design consulting for other structures and boatyards.

Our in-house staff focus principally on the following sectors:

YACHT DESIGN

  • Style drafts and interior design
  • Configuration and pre-project stage
  • Design and EC certification
  • Stability, buoyancy and compartmentation analysis
  • Calculation and analysis of performance and propulsion
  • Structural scantiling
  • F.E.A. structural analysis
  • 3D designing and modeling

ASSISTANCE AND DATA ANALYSIS OF TANKS TEST TRIALS

Over the years, our R&D activities have led us to work in other fields and on other kinds of naval vessels:

  • Fast Ferry
  • Aerospace
  • Hydrofoil
  • Atumation

PROTOTYPE

Creation of models and moulds, right up to the prototype

HYBRID HYDROFOIL

The Magazzú boatyard is presently carrying out extensive research and tests into advanced boat concepts.
Sea trials on a “hydrofoil-RIB” with trimaran hull capable of filtering waves when skimming across water have already been carried out.

Further tests are currently underway on a “hydrofoil-catamaran” configuration.
The aim is to develop a new category of low fuel consumption boat with excellent sea keeping for passenger transport, military patrols or pleasure craft. Unlike previously constructed hydrofoils, this category will allow for the adoption of conventional propulsion systems and avoid the common problem of lateral bulk from the foils.

 

FAST FERRIES

The Magazzù’s lengthy research activity in the field of fast naval transport, produced the innovative idea of stabilising and improving the performance of monohulls by using particular lifting surfaces.

The final industrial result was the conceiving of a totally innovative ship known as “MONOSTAB” (STABilised MONOhull). This was obtained by the integration of a specially developed semi-planing hull and a totally original system of “active foils” at stern, and operated by an automatic control system with the dual role of reducing both the ship’s rolling and pitching motion.

In order to control the trim, conventional flaps are used in parallel to avoid saturating the foils and the unnecessary use of large foil systems.

The foil system and the original streamlined support arms can be completely folded while in port or docked, thus avoiding any manoeuvring problems and increasing the static rolling stability by means of a “trimaran effect” due to a lift from the vertically positioned streamlined arms.

The Magazzù Group (Prof. Magazzù being the author of the Monostab patent) is responsible for both the innovative idea of this fast ferry together with its special shape and configuration, and all the ship’s other innovative design aspects. The Group also provided assistance and technological support on the building of the ship’s prototype, “PERONI”.

The creation of the 37m Monostab prototype (350 passengers and a speed of 35 knots) which started running in the Spring of 1990, was the result of close co-operation between the Magazz˘ team and the RODRIQUEZ group with support from other external companies, both Italian and foreign.

SURFING TRIS

Development of the “Surfing Tris” (patented in Europe, USA and numerous other countries), started back in 1989 with long trials carried out at the Naval Tank Test in Paris. It is a special trimaran where the immersion of the side floats can be varied using hydraulic actuators.

This way they can adapt to the shipís load conditions and their retraction at speed, keeping the vessel balanced with the activation of automatically controlled side foils (fig. 1). That is, with a view to eliminating its own resistance and that of the interference from the floats which, as experimented in the Tank, becomes extremely high.

A virtual slim monohull is thus obtained at speed, not otherwise obtainable because of instability, with added advantages in terms of resistance and sea keeping.

A bow foil is also adopted which is automatically activated with a pitch damping function, and together with the side ones, gives a lift that raises the vessel and reduces the possibility of waves coming into contact with the bottom of the side floats.

This concept, applied to the 75m “Surfing Tris 75” fast ferry, means you can obtain speeds of approximately 6/7 knots faster than monohulls in the same class, with equivalent installed power and load capacity (usually 36/37 knots with 4 MTU 20V 1163 compared to the 43 knots of the “Surfing Tris 75”).

AEREOSPACE – ADVANCED AMPHIBIAN AIRCRAFT

During the joint research work between AERITALIA (now Alenia) and DORNIER (now Deutsche Aerospace Group) to develop an Advanced Amphibious Aircraft, a vast amount of research was carried out, using the support of the Magazzù Group and the technical facilities of Davidson Laboratory at the Stevens Institute of Technology.

The idea was to study, experiment and finalise the most suitable shape for the hull and the possible use of innovative, unconventional devices to increase sea keeping and reduce the “splash down” impact.

The Magazzù Group ís main role was to assist, support and integrate the work carried out at the Davidson Laboratory by proposing, experimenting and analysing innovative shapes for the hull and devices to ease impact. It also developed a specific and original calculation code to simulate and analyse the take off and mooring of the aircraft in question, whose applicability can still be extended to different kinds of amphibious aircraft.

ESA PROJECT

In 2001, the Magazzù Boatyard designed and built an experimental apparatus to be used in a research campaign under micro-gravity conditions, carried out by ESA – European Space Agency.

The apparatus built in composite sandwich and “honeycomb“, as well as being equipped with numerous mechanical and electronic monitoring and control systems had to meet the necessary aerospace construction and safety standards set by ESA and was used successfully in June 2001 during dozens of parabolic flights made with ESA‘s Airbus A300 aircraft.

SYSTEMS

The staff at the Magazzù Boatyard have been developing automatic control systems for years in different sectors and on different applications, from early research carried out on active suspensions and the control of air cushion vehicles, to the study of control logics of stabilising systems for the Rodriquez Group’s hydrofoils and Monstab. They have also developed control systems used both on naval crafts as well as in other industrial areas.

Today, the development of specific software has extended to the use of genetic algorithms and neuronal networks. Staff at the Magazzù Boatyard have, in fact, worked in this sector with important system engineering multinationals such as DATAMAT, in the development of predictive diagnostic systems for applications in the naval industry (SHIDESS programme).

AUTOMATION

To date, staff at the Magazzù Boatyard have developed numerous applications in the field of industrial automation.
From automatic plate cutting systems developed in the ’80’s, to machinery for automatically picking agricultural products, to an anti-freezing system in agriculture, consisting of a 6m diameter propeller with an articulated blade created using innovative construction methods, fitted with an electronic control system capable of automatically activating the propeller according to temperature and wind speed.

More recently, a robot was developed to be used in surroundings harmful to humans. Thanks to a viewing system and remote control as well as special sensors for detecting the presence of obstacles, it can move around autonomously and be guided and monitored by an operator from a safe distance.
