Antoniuk, KaterynaŠkultéty, Filip2023-11-142023-11-142023http://drepo.uniza.sk/handle/hdluniza/955The Viper SD-4 is an excellent example of a Light Sport Aircraft (LSA) category of training aeroplanes. It is produced in Slovakia and used in several European countries and also in the United States of America. It is a very high-quality made aircraft, but some of the pilots say that it has one not very convenient component, which is the operation of the brake system. In this article researched how the brake system can be modified based on data from other brake systems used for the LSA category. The result of this research is the possible variants of the anticipated modifications and the analysis of the relevance of such changes.skhttp://creativecommons.org/licenses/by/4.0/braking systembrakesViper SD-4LSAaircraftmodificationmaster cylinderConference paperhttps://doi.org/10.26552/pas.Z.2023.1.02
