This paper aimed to solve the impact of operational abrasive wear on rotor blades axial compressor turboshaft engine decrease in its total compression efficiency ηCt and transition into unstable work mode (surge). process is analyzed based obtained data by operating TV3-117 helicopter engines high dust atmosphere conditions. Abrasive compressors causes mechanical damage blades, reducing their s...

The traditional model predictive control (tMPC) algorithms have a large amount of online calculation, which makes it difficult to apply them directly turboshaft engine–rotor systems because real time requirements. Therefore, based on the theory perturbed piecewise affine system (PWA) and multi-parameter quadratic programming explicit (mpQP-eMPC) algorithm, we develop controller design method fo...

The engine fuel control system plays a crucial role in performance and economy. Fuel control, traditional systems, is carried out by means of sensor-based methods, which correct the flow rate through correlations or scheduled parameters order to reduce error between measured parameter its desired value. In presence component degradation, however, relationship measurable may lead an increase err...

This paper presents a novel model of large-size tilt-rotor aircraft, which can operate as a helicopter as well as being capable of transition to fixed-wing flight. Aerodynamics of the dynamic large-size tilt-rotors based on blade element method is analyzed during mode transition. For the large-size aircraft with turboshaft engines, the blade pitch angles of the rotors are regulated to vary acco...
