The Ekranoplan: A New Means of Transportation For Yakutia

Posted on April 21, 2015 by team


The future has already come to Yakutia! This spring they are going to start using ekranoplans or ground effect vehicles for passenger transportation. Some technical modifications have been made for the vehicles to adapt them to the local climate conditions. For example, six-blade propellers have been replaced by three blade ones.

The first route for ekranoplan “Burevestnik-24″ will be Yakutsk-Olekminsk. One way flight (including all stop-overs) will take 5-6 hours.

The ekranoplan has three travelling modes: at speed of 30 km/h it floats like an ordinary motor boat, at 120 km/h it starts planing on the water surface, at 240 km/h it raises above the water and activates its ekranoplan function.

“Burevestnik-24″ may transport twenty-four persons including three crew members. It has two engines on the upper wing, with ducted pusher propellers. The ekranoplan has two engines  AviaSmart B-V12K, 421 hp each at the maximum power, 350 hp in a cruise mode.

    Great idea from the Soviet :-)
    Can you explain why 3 blades are better than 6 in cold weather? Thanks.

      Perhaps the blades needed to be wider to accomodate anti-icing equipment?

      The power delivered by the propeller is, amongst others, a function of blade area. If the blades must be wider (to accomodate anti-icing features) then they need to be made shorter or their number must be reduced, otherwise they do not match the power delivered by the engine.

      If these pusher props are made shorter they become less efficient because part of them is already obstructed by the engine and the wing, so instead they decreased the number of blades.

      I could be wrong, in which case I would like to know what the real reason is ;)
