Ivan, JakubČerňan, Jozef2024-11-142024https://drepo.uniza.sk/handle/hdluniza/1136This thesis is focused on creation of propeller concept for wide range of flight speed. The part, which is discussed in the thesis is creation of design for blade motion mechanization, that can reach variable diameters. Apart of creation of this design, the thesis offers historic overview of propeller development throughout the years. Mechanization is designed in 3D environment. The software used for design is Autodesk Inventor. Design isn´t calculated of given engine. The outcome of this thesis is to give perspective for constructers, whoever would want to construct this idea in reality, not 3D environment only. The design in 3D environment is working as it should and when motion is launched, blades are really changing the diameter. In the design study, radius difference between extended and reduced blades is more than 300 millimeters. Desing complies with the task.otherpropellerbladediameterdifferencedesignmechanizationWorking Paperhttps://doi.org/10.26552/pas.Z.2024.1.10
