Modern ground effect vehicles

Among GEVs that are at the stage of sale, the most effective are the following:

9-seats GEV "Volga-2", сcreated by the Central design office of HS (Nizhny Novgorod, Russia) under the direction of the chief-designer V.A. Dementiev according to the theory of eminent chief-designer of soviet combat super ground effect vehicles R.E.Alexeyev.

5-seats GEV "Amphistar", created in the closed company "Technologies and transport" (Nizhny Novgorod, Russia) under direction of the chief-designer D.N. Sinitsyn - disciple of R.E.Alexeyev.

8-seats GEV "FS-8", reated by the Australian company "Flightship Ground Effect Pry Ltd" in common with the German company "Airfoil Development GmbH" under the project of the famous German ground effect vehicle designer Hanno Fischer.

The first two GEVs belong to dynamic air-cushion vehicles that are crated by blowing air flow while their motion in relatively narrow clearance between their lifting surfaces and the "ground". Cruise flight height of these GEVs does not exceed 0,5m that does not let tell about their navigability and limits the area of their use by rivers and small lakes. GEV "FS-8" can be used at more flight heights. Its navigability (by flight and by landing) is valued of 2-3 Beaufort. Use of GEV "FS-8" at the height of "ground" more than 1,5m is connected with the risk for safety of its crew because of the insufficient margin of the pitch stability while flight at low altitudes where there is an abrupt decrease of positive influence of "ground effect".

One should especially mention another Russian GEV:  12-seats GEV "Ivolga2", created in the closed scientific and production company "Trek" (Moscow) under direction of the chief-designer V.V. Kolganov. Experimental prototype of this GEV has successfully passed the sea-going and running trials at the Lena and its source in the region of Irkutsk and in the waters of the lake Baikal. GEV "Ivolga" is devoid of defects of the above mentioned GEVs. Its aerodynamic configuration of "composite-wing"-shape, offered for GEVs by the brilliant aircraft designer R.L. Bartini, lets keep the sufficient pitch stability both while guided and unauthorized escape from the "ground" up to the heights at which its influence is not almost felt. This, together with experimentally craft navigability (by flight and by landing) up to 3-4 Beaufort assures to its crew the sufficient safety while flight over the coastal zones with minimal weather conditions limits. Actually, one prepares its line production at one of Russia aircraft building enterprises.

However, GEV "Ivolga2", the best one with its performance characteristics of all the small GEVs built nowadays, possesses a defect like other contemporary GEVs. It consists in the following: for take-off, all the contemporary GEVs need the power of propulsion plant that several times exceeds the power necessary for its cruise flight at the "ground". Thus, all the contemporary GEVs while operation at their main mode, i.e. while flight at the "ground", have to carry ballast such as main engines and fuel for them. It considerably decreases their shipping effectiveness.
