Transport amphibious platforms are designed for year-round operation at rivers and seas including shallow water areas, as well as ice roads with landing at a gently sloping beach in off-road conditions with natural slopes of up to 6 0 and undulations of up to 1.6 m.
The TAP motion principle is based on dynamic gas cushion effect – supply of pressurized jets from power plant under wing – platform. The TAP concept also uses the "surface effect" in combination with high hydrodynamic qualities of slender gliding hulls.
Unlike WIGs, when moving TAPs remain in contact with water (land) at low specific loads on the supporting surface.
High speed of TAPs (up to 250 km/h) in combination with seaworthy and amphibious qualities and high load capacity reaching 40-50 % of total displacement enables rapid servicing of any transport and special routes of up to 1500 km long (one fueling) both within inland water bodies and open sea at waves of up to 4-5 points. The TAPs are capable of landing at a gently sloping beach.
