UPCYCLING for cargo ships

 

 

 

 

 

Each of the tens of millions of cargo ships that cross our oceans are downsized after their seaworthy

 

operating time in Third World countries.

 

 

 

Instead, these structurally valuable structures could be given a second useful life.

 

 At piers or on land, they would - with a correspondingly extended operating license, expanded as a multi-purpose space - still provide valuable services for several years. Whether as a school, opera, museum, department store, gallery, hospital, restaurant or for communal living - offers such a ship's belly many possibilities. In new buildings, such facilities cost scarce resources, occupy a lot of urban space and hardly have any more of a lifetime.

SAILS for SEATRANSPORT 

 

Inflated wings also for cargo ships

 

90% of all long-distance freight is done on "dirty" sea routes.

 

This should and must be different in the future. Is now also good and cheap to implement! With the simple and revolutionary invention of two Swiss inventors can be realized also 1000 m² sail areas. These perform independently and without strong force on the mast and canvas propulsion work. Large ships can now be equipped with 4 to 6 thousand m² of wind power.

                                          Statements of the inventors of the Inflated-Wing-Sail:

 

 

"It's the first sailboat that really gave me pleasure sailing because it mixes aircraft and yachting technologies ...»

Laurent de Kalbermatten, aviator and IWS creator

 

«IWS offers a sensation of freedom with a balanced rigging while minimizing effort on the boat»

Edouard Kessi, sailor and IWS creator

A concept

BASED ON PARAGLIDERS AND ON INFLATABLE AIRCRAFTS

IWS is made of:

A double skin forming a symetric airfoil

Fans placed inside the leading edge, stabilizing the sail's shape for every wind conditions

Free-standing and retractable mast located at the airfoil's aerodynamic center

 

 

 

The IWS for yachts:

A SOFT AND GROUNDBREAKING WING

 

The advantages

OF IWS:

The sail flies vertically

The NACA airfoil has been studied to develop a high driving force for a low righting moment

Using a symetric airfoil allows to tack to one side of another without having to trim the sail shape

The symetric airfoil is balanced and placed itself in the best position to maximize the driving force

The aerodynamic center stays stable in every wind condition

This kind of sail could easily be driven by an automatic system

 

 

IWS

REDUCES EFFORT ON THE BOAT:

 

Shape control using the internal pressure

no battens

no local stress

better aging

The wing flies vertically and does not create local stress inside the membrane (light sail cloth used for both ribs and the fairing)

Little heel angle upwind

Perfect for gigantic sails such as superyachts

Free-standing, retractable and light mast hidden inside the wing

Less leeway control needed

A refined deck of any hardware

IWS behaves like a muscle,

STABILIZED BY HIGH INTERNAL PRESSURE

No flapping

No dynamic stress

Spectacular absorption of the pitching effect

Wing twist controlled by internal pressure

IWS sailplan

IS BALANCED AROUND THE MAST:

No compression forces in the rigging which allows the use of a retractable mast

No leech tension. The sheet is only used to adjust the wing in its best angle

The free-standing rigging allows gybing with the wing going forward around the mast, which makes the maneuver a lot easier

 

 

IWS controls the sail area

BY MAST HEIGHT:

Mast and sail expension varies according to the desired sail area

Dropping the IWS is made by deflating the wing and retracting the mast

The light boom, called "Nest" ®, is integrated into the wing and receives the part of the sail that has been dropped and deflated

Being able to retract the mast allows a huge decrease in drag and pitch forces during motoring or while at the dock

 

 

IWS

IS IDEAL FOR:

Cruising Yachts A brand new yachting philosophy

Huge sails for passenger or cargo ships. With IWS, there is no more stress in the sail cloth, the rig or the ship structure. This system would allow sail propulsion for this kind of vessel

IWS,

THE HISTORY

2015

prototype created using a laser dinghy.

2016

International patent application.

Comparison between a normal Laser dinghy and one with the IWS system.

Performances and advantages validated.

IWS,

2017 NEWS:

To analyze all the advantages of the IWS system, a 42m² wing has been built for a 5.5m one design boat. The retractable mast made out of 5 sections deploys up to 13m using a pneumatic system

Test period is finished. The boat sails on lake Geneva and is at your disposal for sea trials

Our experience on the IWS proved that this system is very simple, efficient and user friendly.
