Vanin I. Structural-parametric geometrical modelling of wing airplane surfaces during initial stage of design

The work is devoted to development of theory for geometrical modelling of complex airplane wing surfaces. New algorithms and programs for computer-aided design of composite aerodynamic contours of second order’s smoothness are offered in this dissertation. The technique of modelling is shown on an example of wing surface design with using of third order’s Bezier curves. The thesis presents structural–parametrical methodological bases for optimisation of complex geometrical objects. The dynamic changes of functional geometrical parameters are considered as the mathematic mechanism for adaptation of these objects to various conditions of modelling.
