Opis:: The paper presents the results of the calculation of forces acting on the flaps of the Su-22 aircraft during take-off and landing. Four different analytic and experimental calculation methods were used to increase the reliability of the obtained results. The results will be the basis for performance of fatigue testing of the flaps which are structural components of the aircraft wings. The tests will be performed as part of a wider research program aimed at the extension of the Su-22 aircraft service life.
W pracy przedstawiono wyniki obliczeń sił działających na klapy samolotu Su-22 podczas startu i lądowania. Wykorzystano cztery rożne analityczno-eksperymentalne metody obliczeniowe w celu zwiększenia wiarygodności otrzymanych rezultatow. Będą one stanowić podstawę do przeprowadzenia prob zmęczeniowych tych elementow konstrukcyjnych skrzydła samolotu. Proby te wykonane będą w ramach szerszego programu badań, mających na celu wydłużenie procesu eksploatacji samolotu Su-22.

Opis:: The article presents the positive results of the works performed at the Institute of Aviation in Warsaw, associated with modernization of a highly manoeuvrable training jet aircraft to make it reach the standards of increased manoeuvrability. It is shown how the maximum increase of a standard training aircraft manoeuvrability was achieved, which was the result of a small modification of the structure, along with the minimal costs of modernization and qualification tests. The paper also presents the basic process of modernization related to the development of iterative methodology, which includes numerical selection of mechanization elements, that is, strakes, slots and flaps. The parameters of the performed aerodynamic model are demonstrated as well as the results of the tests of its properties with the selected types of strakes conducted in a low-cost aerodynamic tunnel of 1.5 m diameter with the use of a sixelement aerodynamic weight. Parameters of the selected type of strake model with Fowler flap and slots are shown, as well as the results of the tests performed on it in the aerodynamic tunnel of 5 m diameter, and also the results of the buffeting resistance tests conducted in a transonic tunnel. The paper also presents the parameters of the designed optimized strakes, flaps and slots in 1:1 scale, which were mounted onto the aircraft prototype. Finally, the article presents the results of the full cycle of in-flight tests, which confirmed the anticipated project objectives and obtaining of a significant increase in the aircraft manoeuvrability by 48%.

Opis:: The article presents investigation of flow around wing of TS-11 Iskra airplane. The flow visualization around 3D printed model of wing with flow control surfaces was performed in a water tunnel. Two configurations were investigated: first with a flap and second with an aileron. The flow visualisation was performed with a use of a dye. The geometry of model was prepared with use Computer Aided Design (CAD) software basing on scans of real object and technical documentation. The model was built with use of additive manufacturing technology. Movement of the flow control surfaces was remotely controlled with servomechanisms incorporated in channels inside the model. In order to perform qualitative validation of the results the investigated flow was simulated with use of CFD commercial software. The article presents visualisation results of flow around wing section of TS-11 Iskra airplane and water tunnel model preparation. In order to perform qualitative validation of the results the investigated flow was simulated with use of CFD commercial software. The goal of the research was to investigate the complex flow field in the vicinity of flow control surfaces and provide aerodynamic characteristics at various deployment angles via numerical simulations. The results can be used for verification of water tunnel testing procedures and training.
