ABSTRACT. The paper is dedicated to computational modelling of conceptually new amphibious aircraft. Based on the analysis of bionical forms of operational medium there provided are the visual and graphical solutions of the developed model. Sketch drawings considering the requirements of ergonomics are provided, sketch of amphibious aircraft 3D model is created. Based on sketch projects the stage-by-stage 3D modelling of amphibious aircraft structural parts was performed. Modelling has been provided by methods of polygonal extrude. Materials shading and rendering provided at sub-object level. There provided are the scenes of rendering of shaded 3D model of amphibious aircraft.

Introduction. Today hydroaviation is actively used in different fields, starting from fire-fighting and effective-rescue operations up to passenger traffic. The issues of applying modern technologies of modelling for aircraft designing are challenging. The most important stage is the development of preliminary concept of transportation means. Let us review some of the modern literary sources in this field. The article [15] is dedicated to conceptual designing of aircraft, where aerodynamic properties of bird wings are considered. The works [14], [18] study the issues of designing economical passenger aircraft. The article [7 provided and analysed are the different variants of aerodynamic configurations. The work [8] contains the peculiarities of conceptual designing of new generation of supersonic aircraft with original arrangement of landing gear and fuel tank. Article [9] describes the peculiarities of implementing modern program tools for the purposes of designing. There described are the possibilities of new program for aircraft structure development. The issues of conceptual designing initial stage are described in detail in book [13]. There provided is the methodological base of idea generation stages, determination of initial requirements for future structure. The book [23] contains the peculiarities of preliminary and conceptual designing of aircraft. Modern systems of automated designing are described in detail. This work is dedicated to three-dimensional computer-aided modelling of new concept of amphibious aircraft. It is supposed that the developed model will be in the middle segment of hydroaviation market. In the result of amphibious aircraft market review we can remark the following aircraft of low passenger capacity up to 25 persons: Be-103 produced by Beriev Aircraft Company [21], flying amphibious boat Airmaster Avalon-680 produced in the USA, amphibious aircraft Do-24 produced by German company Dornier Seastar [20]. For the developed model the crew will consist of 2 persons, the passenger compartment can contain up to 24 passengers.
