Chumak A. Transport category airplane fuselage nose section integrated design method

Object of research – computer integrated design of transport aircraft; Goal of research – develop a method of integrated design of the fuselage nose part using computer systems to increase the efficiency of new ukrainian transport aircraft; methods of research – methods of general design of transport category aircraft, system design methods for analysis of features and synthesis of rational configuration of the fuselage nose part, methods of parametric three-dimensional modeling using CAD/CAM/CAE/PLM Siemens NX, finite element method implemented in ANSYS systems, Siemens NX NASTRAN; computational and experimental methods for determining the influence of geometric parameters of the fuselage nose part on the performance characteristics of the aircraft; the results – important scientific and technical task of developing a method of integrated design of the bow of the fuselage using computer systems to improve the efficiency of new domestic transport aircraft is solved; novelty – method of integrated design of the fuselage nose part of the transport category aircraft is developed for the first time with the use of parametric models of master geometry, aerodynamic flow and mass-inertial characteristics of the fuselage, taking into account design features and requirements for layout and view field from the cockpit; rational shape of local airlines aircraft fuselage nose part is justified at the early stages of design for the first time, taking into account the requirements of the terms of reference and current regulations, which improved the aircraft flight performance and fuel efficiency; estimation methods for aerodynamic and mass characteristics of the fuselage at early stages of design are improved by implementing parametric finite element models and CAD / CAE systems Siemens NX, NASTRAN and ANSYS; the concept of a new aircraft for local airlines and its modifications taking into account the peculiarities of operating conditions was further developed; degree of implementation – the results were implemented in the production of State Enterprise "ANTONOV", Kharkiv State Aviation Production Enterprise and in the educational process of the National Aerospace University. ME Zhukovsky "Kharkiv Aviation Institute"; field of application – aerospace industry.
