Moreover, the hovercraft's special coating enhances lift by 40 percent (with the help of turbulence flows). Consequently, the EKIP's payload accounts for only 40-45 percent of its mass; meanwhile the relevant aircraft ratio is 20-25 percent.The structural/engine weight and the fuel weight of the craft are overhead, and this basically claims that that weight is very low for the cargo capacity. Looks to me like a claim of a very high lift-to-drag ratio, combined with a high structural efficiency.The EKIP boasts some other unique specifications; for example, it can transport 100-ton loads over several thousand km at 500-700 kph and at 8-13-km altitudes. This unique hovercraft can skim along at 160 kph just above the surface.
And as such, an enormously valuable characteristic. Unless of course it can only be made out of mockingbird tongues . . .
