FLOAT-TYPE SEAPLANE OF CATAMARAN CONFIGURATION-SEA-GOING SALVAGE VESSEL Russian patent published in 2006 - IPC B64C35/00 B60V1/08 

FIELD: aircraft manufacture; manufacture of seaplanes for conducting search and rescue operations.

SUBSTANCE: proposed float-type seaplane is used for rescue of people at sea swell number 5; it is provided with fuselage with additional elevators in nose section for enhancing the seaplane controllability and engines for supercharging under center-wing section located in nose section of fuselage in technical compartment for forming air cushion under center-wing section and blowing-off incoming wave; seaplane is provided with pilot cabin. Seaplane is provided with delta-type low-set swept wing. Center-wing section extends over entire length of fuselage performing the function of main load-bearing structural member of seaplane connecting together fuselage, twin-fin unit tail, with mid-positioned stabilizer on which cruise turbo-jet engines are installed and two parallel elongated floats of deadrise or torpedo-like form; they are secured on pylons under center-wing section. Mounted on floats and in nose section of fuselage are three dampening sliding water ski extended during takeoff and landing and retracted in flight.

EFFECT: enhanced stability, seaworthiness; reduced hydrodynamic and aerodynamic drag; enhanced strength of seaplane construction and its controllability.
