353--360

The paper presents a modelling procedure of the M-28 Bryza wing with extended flaps and Computational Fluid Dynamics (CFD) simulations results preformed in order to assess the performance of the investigated wing for various flap extension rates. The M-28 Bryza is a two-engine high-wing aircraft used in the Polish Air Force for short distance airlift of people and equipment. The aim of this work was to determine the aerodynamic characteristics of the investigated wing. The CFD simulations were performed in order to investigate the influence of flap extension on lift and drag coefficients at various angles of attack. In order to validate the results of two different commercial CFD packages were used. The findings are presented in the form of flow visualization and aerodynamic characteristics. The typical and non-standard extension rates were investigated for low, moderate and high angles of attack. The results correlated with the limitations specified in the aircraft manual. The outcome of the presented work confirmed the feasibility of the presented methodology for its use as a supportive tool for providing additional information about airplane performance in standard and non-standard conditions of flight such as landing with one engine working. The results of work might prove useful for M-28 Bryza pilots and maintenance personnel as well as for educational purposes.

Rozwój komputerów znacznie odmienił charakter pracy inżyniera. W klasycznym podejściu projektowany obiekt powstawał w wyobraźni projektanta a materialną formą projektu był zbiór dwuwymiarowych rysunków technicznych. Współczesne oprogramowanie pozwala zbudować wirtualny projekt w przestrzeni trójwymiarowej. Projekt ten może być przetwarzany na wiele sposobów. Inżynieria odwrotna (Reverse Engineering) polega na budowie modelu numerycznego na podstawie rzeczywistego obiektu. Założono utworzenie modelu samolotu M-28 Bryza o wymiarach rzeczywistych, złożonego z części, aby możliwe było odwzorowanie ruchu wybranych podzespołów w celu przeprowadzenia odpowiednich badań aerodynamicznych bez absorbowania obiektu rzeczywistego.

The development of computers has tremendously changed the character of the engineer’s job. In the classic approach, the designed structure was imagined by the designer. The consequent physical form of the project was a collection of 2-D technical drawings. Modern software allows to build a virtual project in a 3-D space. This design may be processed in a number of ways. Reverse Engineering consists in building a numerical model on the basis of a real structure. The assumption was to create a real size M-28 Bryza aircraft model, which would be composed of parts so as to copy the movement of the selected components. This, in turn, would enable to conduct proper aerodynamic investigation without using the real structure.
