A low bypass ratio turbofan engine operates in a hostile environment, resulting performance degradation. This seriously affects the security and reliability of engine. Therefore, degradation evaluation method for engines based on flight data is proposed. The expands equation system to solve underdetermined problem caused by lack sensors multiple operating point analysis. improved evolution algo...

The active jet noise control received significant attention due to the little influence it has on engine performance. is a multivariable problem because needs achieve simultaneous closed-loop of and Model predictive (MPC) great application potentials in field aero-engines, but real-time performance MPC intractable. This paper proposed an controller turbofan engine, based explicit model (EMPC). ...
