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%.
