Abstrakt: Solution of the replacement of plastic lubricants of the Mobil-NLGI 00 type (to the PSU-planetary directional device) and Total-NLGI 0 (to the KP-final gear) for the MAPU-1 (in PSU) and MAKN-2 (in KP) lubricants. The design of plastic lubricants was performed in cooperation with Armed Forces Academy of General Milan Rastislav Štefánik represented by Ing. Miroslav Marko, PhD. and CMaS ZZ II Žilina, represented by Ing. Stanislav Kolomazník within the Project VV-1/2018 to 2020. Testing of PM (plastic lubricants) was performed on a special vehicle type GM 578. After changing MAPU-1 and MAKN-2 lubricants for PM (NLGI 00 and 0) and running 197 km was carried out “1. Check collection”. Further inspections will follow in the next period. On behalf of Armed Forces Academy of General Milan Rastislav Štefánik, Major was also actively involved in tribodiagnostics Ing. Vladimír Kadlub and Capt. Ing. Pavol Lukášik.

Kľúčové slová: PSU-Planetary directional device; KP-Final transfer; PM-Lubricants; NLGI-Lubricant penetration scale, which is standardized in ISO 6743/9, resp. in STN ISO 65 6901.

Abstrakt: The use of unmanned vehicles - both civilian and military - is clearly a technological trend today. It is reasonable to assume that this trend will continue in the future. Especially in the military field, an unmanned vehicle can be considered a benefit, especially in applications where the use of "standard" equipment is difficult or impossible. This is especially true of Unmanned Aerial Vehicle (UAV). The flight itself represents a number of different types of stress affecting the design of the unmanned aircraft. Therefore, the design of such a device must be subjected in the first step to a computational strength analysis and subsequently to a real stress test. Our paper deals with the strength analysis of the most exposed structural element - the wing connector. Proper sizing of the wing connector is therefore crucial for the successful operation of the UAV.

Kľúčové slová: UAV; Wing connector; Normal bending stress; Strength calculation.

Abstrakt: Use of an appropriate DSL can significantly reduce development time. This is due to the fact that DSLs are limited to the use of terms relating to the explicit domain, which makes them much easier for programmers to understand and learn. Despite these and other advantages of DSLs over GPLs, programmers will only exceptionally turn to DSLs in development process. Therefore, in this article, we will look closer on what DSLs are, when it is appropriate to use them in a project and when not. In the last part of this article, we will focus on the possibilities of using DSLs in the field of information security.
