AMPHIBIA Russian patent published in 2001 - IPC

FIELD: transport engineering; amphibian vehicles. SUBSTANCE: proposed vehicle has body and propulsion gear with blade wheel installed in body stern. Stern is made in form of cross-flow fan housing made together with surface of medium. Fixed hollow body is installed inside blade wheel at positive angle of incidence to direction of movement. Hydrofoil is installed at level of lower plane of hollow body behind blade wheel and in parallel to wheel axis. Fixed hollow body can be connected with engine exhaust duct being constructively made as muffler. Body stern can include elbowed upper plane, intake branch pipe with turnable louvers, outlet branch pipe smoothly changing into body tunnel, and side walls. Lower plane of intake branch pipe is made in form of reverser. Lower edges of side walls can be provided with flexible guards. Blade wheel should be preferably made drum-like. Proposed amphibian vehicle is made for easy negotiation of swamps, water, snow, ice, grass-covered terrains being capable of changing from one medium to the other without preliminary preparation at all speeds of range with possibility of use of aerodynamic off-loading in motion. EFFECT: enlarged operating capabilities. 4 cl, 3 dwg
