In this study, the performance analysis of engine was carried out according to parameters determined by parametric cycle in turbofan engines with afterburner and separate exhaust streams. The main purpose study is determine relationship between values, design flight ambient values. For this, effects Mach number, compressor pressure ratio bypass values on specific thrust, fuel-air ratio, fuel co...

This article presents the development of electric turbofan engine in distributed architecture with a design thrust range 3 to 7.5 and from 30 kN for small medium-sized unmanned aerial vehicles. The subsystems are considered as separate smart modules built-in control system, exchanging data via digital channel central diagnostics unit. key units combined following subsystems: starter turbine gen...

Among the various data-driven approaches used for RUL prediction, Recurrent Neural Networks (RNNs) have certain prima facie advantages over other approaches because the connections between internal nodes form directed cycles, thus creating internal states which enables the network to encapsulate dynamic temporal behavior and also to properly handle the noise affecting the collected signals. How...

Aircraft range is one of the most important criteria of the assessment of the performance properties of an aircraft. For the needs of the paper the mathematical model of an aircraft (multi-purpose aircraft) and the engine which propels the aircraft was built (turbofan, two-spool, with jet mixer). For the analysis it was chosen so-called typical Breguet model and the conventional range. The mode...

This study proposes a strategy for improving the thrust performance of fixed-wing UAV turbine engines from perspective aircraft/engine integration. In engine control process, inlet distortion caused by angle attack change is taken into account, index calculated in real time predicting attack, and influence on model analyzed mechanically. Then, pressure ratio command adjusted according to new co...
