Virchenko G. Geometrical modelling of airplane surfaces in integrated computer-aided design systems with using of third order's Bezier curves

The work is devoted to development of geometrical modelling of airplane surfaces with using of third order's Bezier curves.New algorithms and programs for modelling of composite planar contours of second order's smoothness with using of computer-aided design are offered in this dissertation. The thesis presents structural-parametrical methodological bases for designing and optimisation of complex geometrical objects. This task is very important during the creation of airplane shape. The technique of structural-parametrical modelling for complicated objects is shown on an example of fuselage surface designing. The dynamic changes of functional geometrical parameters are considered as the algorithmic mechanism for adaptation of these objects to various conditions of modelling.
