TRANSPORT FACILITY DYNAMICALLY SUPPORTED BY AIR CUSHION Russian patent published in 2005 - IPC

FIELD: shipbuilding; building of dynamically-supported amphibians.

SUBSTANCE: proposed transport facility has hull, wing with flaps, vertical tail with rudder and stabilizer, side skegs and pneumatic bottles whose outer shells are provided with planing steps. Engine with propeller unit is located in front of leading edge of wing. Side skegs are located over edges of wing in parallel relative to axis of hull. Side pneumatic bottles are mounted in lower portion of side skegs and central pneumatic bottle is located on lower surface of wing and hull along hull axis; its lower edge lies above lower edges of side pneumatic bottles. Upper boundary of planing steps is matched with upper edge of outer shells of pneumatic bottles and skis are located along lower portion of pneumatic bottle shells. Height of skis exceeds height of planing steps. Arranged inside outer shells of pneumatic bottles are longitudinal stiffening members. Central pneumatic bottle is so positioned that its fore edge is shifted relative to leading edge of wing towards fore portion of hull at distance no less than half wing chord; height of its lower edge above lower edge of side pneumatic bottles is found from the following relationship: where Δh is height of lower edge of central pneumatic bottle, mm; l_w is wing span, m; λ is wing aspect ratio. Height of ski cross section may be no less than 1.5H_pl and its width, 5H_pl where H_pl is height of planing step.

EFFECT: improved service characteristics of dynamically-supported transport facility.
