The article presents results of static and towage tests in experimental pool on solid and
water surfaces of a dynamic similar model of amphibian air-cushion vehicle. The aim of
the tests was the search for optimal parameters of air-cushion vehicle, such as: form of
flexible fence; air flow rate in air-cushion system; centring (mutual position of gravity
and pressure centres); trim and list stability on water and solid surfaces; minimized mo-
tion resistance. This aim is to be achieved without dividing air cushion area on long and
cross sections. It reduces labour-intensiveness of maintenance work. As a result of re-
search the aim was achieved.
Key words:
amphibian, vehicle, air-cushion, stability, towage test, hydrodynamic re-
sistance.
