![]() This latest incarnation of the Lippisch design is 56.4 ft (17.2 m) long, with a reverse delta wingspan of 49.2 ft (15 m) and a carbon fiber reinforced plastic body to help keep weight down. Lippisch's reverse delta design could operate at altitudes as high as 50 percent of its wingspan, meaning his craft could either handle rougher seas, or be made significantly smaller and more convenient to use with existing marine facilities.Īnd so to the Airfish-8. ![]() At the time, the chief competition was Russian-built Ekranoplans, with multiple wings, but these couldn't handle rough seas, because they'd come out of ground effect at altitudes just 10 percent of their wingspan. Alexander Martin Lippisch, who pioneered the reverse delta/T-tail configuration in the 1960s. The history of Wigetworks' Airfish GEVs is interesting, with the company now producing its own aircraft, based on designs, patents and prototypes it bought from AirFoil Development GmbH.ĪirFoil Development's Fischer Flugmechanik subsidiary was a vehicle for the GEV designs of Dr. Numerous attempts have been made to capitalize on this effect for quick, efficient transport over water, but right now, the leading players appear to be Sea Wolf Express, which plans to begin a passenger ferry service between Helsinki, Finland and Tallinn, Estonia, using a Russian-built Ground Effect Vehicle (GEV) in 2019, and Wigetworks Private Limited, operating out of Singapore. The ground effect increases the closer you get to the surface, peaking at an altitude around 5 percent of the wingspan, where you can get a craft operating some 2.3 times as efficiently as if does in free air. The additional air pressure underneath the aircraft at altitudes below half the wingspan adds extra lift, and you also get a corresponding reduction in lift-induced drag. ![]() The wing-in-ground effect is well understood at this point: when an aircraft is close to the ground, it operates significantly more efficiently than it does higher up. The Airfish 8 hovers serenely between two and 23 ft (0.6 to 7 m) over the water and hits speeds of almost 120 mph (193 km/h). However the real identity can be concluded by looking at the skull, it's most likely some type of whale particularly a beluga or an orca, with the skull matching that of such creatures (the little notch in the skull being seen in one of the photos).A Singaporean company has resurrected a post-WW2 German design to commercialize a beautiful reverse-delta ground effect vehicle as a high-speed, high-efficiency ferry for six to eight passengers. ![]() According to its skeletal remains, it was not a crocodile or alligator its skull resembled that of a canine, while the creatures rear coincides with that of a fish. The Creature Has been indentified as a beluga carcassĪccording to a scientific survey, the bones and teeth are not of a fish. Sakhalin area is situated near to Japan, it's the most eastern part of Russia, almost 5000 miles to East from Moscow. Sakhalin Island Sea Wolf was a mutilated cetacean corpse that was found by Russian soldiers on the Sakhalin shoreline. What cryptid are you? Click to take the quiz.
