This research describes the function and principles of ignition systems in aircraft reciprocating engines. Physical-chemical processes, which are part of combustion, and the factors affecting them are defined in detail. Types of ignition systems are divided based on main parts and frequency of appearance in aircraft engines. Components of ignition and their function in electric and magnetic circuits are individually described. The future development in ignition systems is defined. The research includes an analysis of the pros and cons of laser ignition in its application in aviation. It presents Low-Temperature Combustion or Volumetric Ignition using Low-Temperature Plasma. An example may be the Microwave-assisted Plasma Ignition System. Engine speed and vacuum in intake are the main parameters influencing the ignition timing curve in Electronic Control Unit Master developed by IMF Soft. This ECU is used in the designed ignition system of testing engine. The designed timing curves were tested, and the results of engine power and torque were compared. In conclusion, the optimal timing curve is evaluated for this reciprocating engine.

Plichta, Dávid; Bugaj, Martin
Safety has always been the main concern of successful aircraft operation. Key part of the operation has to be maintenance, which not only removes defects should they arise, but also prevents them from happening in the first place. For this very reason it is necessary to have a reliable maintenance program and practices. In recent years emphasis has been posed on thorough analysis of aircraft and its systems. This is made ever so easier thanks to tools such as the digital twin. Our goal is to research this recent trend and showcase its possibilities. This wouldn't be possible without our previous underlying studies about Industry 4.0, its related matters including maintenance, as well as digital twin itself. Finally, it is important to note that the main goal of our work is not necessarily the creation of the twin, but rather the subsequent measurements, tests and analysis.

Kachel, Josef; Rostáš, Ján
The subject of this article is focused on the description of the overhaul process involving a classic aircraft design, which is registered under the administration of the Light Aircraft Association of the Czech Republic. The research is divided into three chronological parts; the introduction, the main part and the conclusion. The first part outlines the subject of the research and its individual objectives. The main part deals with the historical background of the Piper Cub type and the current state of operation in the Czech Republic and Slovakia, both from the technical and legislative point of view. A description of the given aircraft will follow and then, mainly, the elaboration of each part of the overhaul process and its individual procedures. Among the individual steps, there will be a description of the required process for increasing the maximum take-off weight of the overhauled aircraft. In the final part, the evaluation of the inputs described above will be performed and the results of the given study will be outlined. The research should provide a comprehensive description of appropriate maintenance and the overhaul process in complexity involving the vintage classic aircraft design under the legislation of the ultralight aircraft category. Another output will be the definition of a procedure for increasing the maximum take-off weight thanks to new, updated legislation.
