Elfly's seaplane hull design is being tested on the SINTEF towing tank in Trondheim. IN
"It will be a kind of flying boat withbattery powered. The goal is to provide passenger mobility in Norway with zero emissions and significantly reduced noise pollution,” explains Erik Lithun, CEO of the Norwegian company Elfly.
The company notes the importance of development“a fundamentally new building.” “The challenge is to find the perfect combination of aerodynamics and hydrodynamics,” explains Kourosh Kushan, research scientist at SINTEF.
Testing takes place in the model tankSINTEF ships in Trondheim. “We are testing the hull by towing it at different angles and evaluating how this affects water resistance,” explains Kushan. Now Elfly Group has developed and is testing the fourth version of the model.
The study, which will provide data for optimal hull design, is a special research project funded by the Regional Research Foundation of Norway.
If Elfy succeeds, the plane of the future will beelectric, environmentally friendly, quieter and fly on shorter routes and from more locations. “We're talking about zero emissions and an electric motor that makes only a faint hum,” explain the project's authors. The seaplane will take off and land on water, and will also be equipped with equipment that will allow it to take off from airfields.
“It should fly 200 km at a speed of about 250 km/h. The flight time from Bergen to Stavanger will be 40 minutes, compared to four to five hours by car,” the engineers conclude.
