Today (April 16), Hainan independentlydeveloped WIG achieved dual boat test for the first time in Guilin Ocean,Haikou, which also means that the technology matures, the development, andmanufacturing fields of WIG in Hainan Leading in the world. According to theperson in charge of Hainan Yingge WIG Manufacturing Co., the vessel will entermass production in the second half of this year, the WIG will be widely used intourism, agriculture, marine, military, etc., help in the construction ofinternational tourism island, WIG boat speeds at 200 kilometers per hour, itwill greatly shorten the travel time between Haikou and Sanya, as well as Sanyato Sansha.

According to reports, known as WIG flyingboats, combined aviation technology and marine technology, bearing advantagesfrom both technologies, accelerating after two hundred meters in the lake orsea, able to continuous flight for more than two hours, as long as the watersfields are about 400 square meters, WIG will be able to freely land in thewater. WIG advantages are: less overall investment, without the construction ofa large runway, terminal and other comprehensive facilities; rapid flightspeed, 10-15 times than vessels, 3-5 times of a speedboat; big load ratio of50% of self-weight, the load proportion of aircraft is less than 20%; a widerange of applications, in the sea, ice, desert, grassland, swampunhindered landing and flight; can avoid radar and sonar scanning, can bewidely used in military fields. Ground effect vehicle is a way to reduce theinduced drag, and can get more efficiency from the Effect of hydrodynamic liftto drag ratio: When the aircraft flying close to the ground, due to the lowerfloor reduce wash down of the wing, the entire aircraft pressure difference isincreased, and thus in the case of constant angle of attack to increase lift,reduce induced drag and increased pitch stability of the aircraft.
