Opis:: For the last several years the combinatorial-cyclic method of optimization has been validated and expanded to new areas of applications. Although coordinate measurement analysis still is the main area of applications, the method is becoming a useful and unique tool in design optimization, reverse engineering (parametric design included), and virtual engineering. The case study aerodynamics of airplane and turbine airfoils, and simulation of wind tunnels is very difficult and promising as well. To solve all problems arising in these areas, an extensive software within the integrated CAD/CAM /CAE system has been developed, written in GRIP (SIEMENS NX 3.8).

Opis:: Topics below are rather undesired, but important, outcome not yet completed research on the aircraft airfoils, turbine and compressor blades, parametric design of airfoils, establishing the relationships based on the results of experiments in a wind tunnel, developing databases for determining the relationships between airfoil parameters and lift and drag coefficients. Reliable database created as a result of the research work allows to simulate the wind tunnel. Very early on, however, was necessary to extend the developed specialized software for a new applications, and it meant the need for generalization of software, e.g. for gas turbine engines, propellers, etc. But after some time it turned out, that in order to achieve the required accuracy, the changes are needed in the underlying assumptions, set decades ago. In addition, coordinate measuring machines and systems, and associated software were not always as accurate as expected. Concepts how to solve it and develop software carrying out these tasks are presented in the article. It is like to withdraw from the old path and look for a new path that will lead to the reliable data base. Processes related to air or gas flow should be similarly defined in all the specialized software applications (e.g. aircrafts and turbine engines). Accuracy (10-9 mm) achieved in virtual measurements within the integrated system can be used to verify the results of CMM and other measuring systems, provided that an appropriate software has been developed.

Tytuł:: Optimization of wing parameters to achieve minimum weight at defined aerodynamic loads
Optymalizacja parametrów skrzydła minimalnej masy z uwzględnieniem ograniczeń do obciążeń aerodynamicznych

Opis:: The paper presents the method suitable for optimization of parameters and applied to design aircraft subassemblies on the example of a swept wing. It outlines the assumptions that are necessary to develop a mathematical model and describes constraints that served as the basis to develop an algorithm and describe the corresponding procedures in the GRIP (Graphics Interactive Programming) language that is a part of the CAD/CAM/CAE Unigraphics system. The further part of the study comprises discussion how the wing parameters and the mass functional are affected by the rigidity constraints and strength constraints. The algorithm for designing aircraft components was finally developed with inputs to the multicriteria design process “Web Modelling” of an aircraft body. The study also includes initial assumptions to algorithms originally developed by the author and dedicated to the modelling of components incorporated into aircraft structures.
W artykule zaprezentowano metodykę optymalizacji parametrów w zastosowaniu do projektowania zespołów samolotu na przykładzie skrzydła skośnego. Przedstawiono główne założenia niezbędne do opracowania matematycznego modelu. Opisano ograniczenia będące podstawą do utworzenia algorytmu i opisania procedur w języku GRIP (Graphics Interactive Programming) dla systemu CAD/CAM/CAE Unigraphics. Przeprowadzono dyskusję zmiany parametrów sztywnościowych i masy w zależności od ograniczenia obciążeniami aerodynamicznymi. Opracowano algorytm projektowania zespołów składowych samolotu z uwzględnieniem wejść do wielokryterialnego procesu projektowania Web Modelling bryły samolotu. W pracy zawarto założenia opracowanych przez autora i zastosowanych algorytmów modelowania elementów struktur lotniczych.
