FIELD: building of transport amphibian hovercraft with elastic guard. ^ SUBSTANCE: propose amphibian hovercraft has platform with built-in receiver provided with compartments, hull with compartments, engine, fan, transmission, propeller in aerodynamic ring, aerial rudder, flexible guard in area of increased pressure, controllable wheeled pneumatic undercarriage, buoyancy units articulated with platform body and elastic guard and safety strake located over perimeter of amphibian hovercraft; it is provided with two deceleration flaps and control system, guide knives and deceleration tenons. Knives are rigidly secured to lower elastic plates of deceleration flap driven by pneumatic cylinders; deceleration tenons are elastically secured to upper plates of deceleration flap and are driven by pneumatic cylinders and corrugated air chambers. Amphibian hovercraft is provided with controllable reactive grate -compensator with horizontal blades for counter-acting to capsizing moment of propeller; it is kinematically linked with contact pitch sensor located in fore portion of hull. Deceleration flap may be divided in plan into two parts located symmetrically relative to longitudinal axis of amphibian hovercraft at distance of 0.3-0.5 of height of air cushion from each other and interconnected by means of flexible spring. ^ EFFECT: improved service characteristics of amphibian hovercraft. ^ 3 cl, 7 dwg |
