Abstract: The article investigates the possibilities for the miscibility and practical use of different concentrations of biofuel rapeseed fatty acid methyl ester (FAME) with aviation kerosene Jet A-1 (or aviation kerosene PL-7 used in the Air Force of the Slovak Republic) in aircraft jet engines. The main objective of this research was the experimental verification of the technical possibilities of reliable operation of the experimental engine SJE-20 in a special laboratory of small jet engines using different concentrations of the mixture of aviation kerosene Jet A-1 and biofuel FAME and their influence on the selected operating parameters of the experimental engine. The motivation for this research is the desire to replace conventional aviation fuels with fuels that can be obtained from renewable sources. Investigation of the possibilities of powering the experimental SJE-20 engine with a mixture of traditional aviation kerosene Jet A-1 (PL-7) and rapeseed fatty acid methyl ester FAME was the subject of the internal project BIOFUEL (Biofuel for Aviation).

Abstract: Article presents original way of solving problem of the impact damage of the gas turbine blades on the parameters of the experimental jet engine MPM-20 with application CAD and CFD software. The article presents this particular application, available methods and future possibilities. The core of the article presents the analysis of the impact of the damaged rotor blades gas turbine on the thermodynamic parameters of the experimental small jet engine MPM-20. To monitor the impact of the damaged rotor blades on the character of flow through the gas turbine stage experimental small jet engine MPM 20 was elaborated mathematical model with the use of CFD software. The results obtained of the mathematical modelling compared with the results of the thermodynamic calculation the stage gas turbine experimental small jet engine MPM-20 showed only slight variations.

Abstract: This work is dedicated to the transformation of aviation turboprop engine AI-24 for energy purposes. The paper provides an analysis of engine construction, design modifications analysis of main components for energy use, as well as analysis of major engine systems. Thermal cycle engine is calculated for first cruise mode. It also discusses the legislative formalities and requirements associated with aircraft engine modifications for energy purposes. The work is also devoted to analysing the actual state of the engine and its inspection. It is a procedure for checking the actual condition of the air turboshaft engine. In the end, it evaluates the use of motor AI-24 for power generation purposes and proposes the possibilities for solving problems of implementation of aircraft turboprop engines for energy purposes.
