The purpose of this bachelor thesis is to design a braking system for ultralight aircraft. The introductory part of this work is focused on a research study of brake systems and their possible control, in terms of advantages and disadvantages for a given type of aircraft, as well as in terms of ergonomically appropriate arrangement of controls pedals. The theoretical part also includes the analysis of the load pressure during the landing of the aircraft and the distribution of hydraulic fluids used in the brake system. In the second, practical part, the work focuses on a new design of the brake pedal, as well as on the calculation of the aircraft load during landing and the determination of the maximum braking force at which there is no ris...
