JEC Group have brought together the international community of composites leaders and executives in our Composites Circle as an unique networking opportunity to meet with both peers and future partners.
Professor and Architect Mark Goulthorpe, of the MIT Department of Architecture, confirmed as guest keynote speaker for the Future of Composites in Construction.
By harnessing the lift generated by flying close to the water surface, Wing In Ground (WIGs) are able to travel at 200-210 km/h and up to 15m above the sea level with only a third of the fuel consumption associated with modern planes.
After two decades of product development by different nations, these oddities are starting to be considered for commercial flights. One of the pioneers is CSIC (Hainan) Wig Craft Development in China that builds state-of-the-art WIGs using Diab core material.
In between a boat and a planeA WIG craft is more or less a boat that cruises just above the water surface (around 15 m above the sea), thereby reducing hydrodynamic drag to a minimum. By flying so close to the surface, the WIG generates a cushion of air that it rides on, using much less fuel than ordinary aircraft. It does not require fixed runways and is safe and friendly to the environment due to low use of energy and exchange of fluids with the sea.
The WIG-technique was actually first used by the Wright brothers when they flew their first aircraft ‘The Flyer’ in 1903. It was later applied by the Russians, who also hold the record for building the largest WIG ever – the 540 ton Caspian Sea Monster with a wing span of 40 m that was capable of skimming just meters above the sea at speeds of up to 500 km/h.
Divinycell-cored WIGs from ChinaToday’s WIGs are generally much smaller. The Chinese manufacturer CSIC (Hainan) Wig Craft Development specializes in the development of WIGs that can carry maximum 7 people, including the pilot. Allowing the passengers to combine the excitement of a high speed boat with the convenience of an aircraft, they could be useful for transportation among the small islands in South China Sea.
For all main structures of the boat, CSIC (Hainan) Wig Craft Development uses Divinycell H80, which reduces weight by 15% compared to traditional monolithic structure, increases load capacity and improves structure stiffness and sound/heat insulation. H80 helps the whole structure of WIG to withstand the dynamic load such as water impact load during the taking off and landing from and onto the water surface.
Divinycell H80 also increases the buoyancy of the WIG, which means the boat can float even if it becomes damaged.
