Design of the reference model of the aero l-39 aircraft
(University of Zilina, 2021) Staňa, Ján; Škultéty, Filip
The object of the research of the paper is to design a reference model of an unmanned aircraft according to the model of the training jet Aero L 39. The work contains an analysis of the methods, procedures and typology used in the creation of reference models. Subsequently, the design of an unmanned vehicle was created using computer modelling, which was subjected to aerodynamic simulations and strength analysis. Aerodynamic performance was investigated on the airframe of the aircraft and strength analyses were determined on specific structural elements. After successful program tests, a functional model of the aircraft was built. The prerequisite was mainly aerodynamic analyses, which should determine with sufficient accuracy the basic structure of the model's flight. The result of solving the problem is a functional model of the aircraft, which is suitable for flight tests using appropriate hardware.
