Methods of integrated computer-aided design of structural elements of the aircraft
Previously applied methods of designing aircraft based on two-dimensional geometric models that made it impossible to take into account all the necessary design and technological features. It was a prerequisite for the development of an integrated methodology that includes design and computer simulation of three-dimensional parametric design of the aircraft as a whole and its individual parts [2-5]. In this paper, the method of computer-aided design stringer at the master model geometry and space allocation wing aircraft. In article approaches to integrated computer-aided design. These types of problems preliminary design and the method of calculation of typical aircraft structural elements for example longitudinal force element sets as stringer. Also, the algorithm constructs a fully stringer system aided design of integrated Siemens NX. What can shorten the design time and use it as a reference for the calculation and further change just values for other dimensions stringers. Methods integrated design ensure the application of standard parametric analytical stringers in the calculation of aerodynamics and strength, life and vitality, weight of the aircraft and its alignment, safety of structures, as well as technological preparation of production and quality control, maintenance and repair. Considered aided design techniques can be extended to other than the stringers typical elements airframe.
