Improved Turbine Engine Hierarchical Modeling and Simulation Based on Engine Fuel Control System

Aircraft engines constitute a comp‌lex system, requiring adequate mon-itoring to ensure flight safety and timely maintenance. The best way to achieve this, is modeling the engine. Therefore, in this paper, a suitable mathematical model from engine controller design point of view, for a specific aero turbine engine is proposed by the aid of MATLAB/Simulink software. The model is capable of reduc...

Dynamical Analysis and Control of Jet Engine Systems

In the recent years, the main obstacles for raising the operating efficiency are instabilities of the compressor system. The related dynamics and control schemes then cause lots of interests among engineers and researchers. Two main phenomena, which cause the instabilities, are the “surge” and the “stall” behaviors of the compressed gas. The so-called “surge” is characterized as a one-dimension...

response articles: micro and macro analysis

the present study reports an analysis of response articles in four different disciplines in the social sciences, i.e., linguistics, english for specific purposes (esp), accounting, and psychology. the study has three phases: micro analysis, macro analysis, and e-mail interview. the results of the micro analysis indicate that a three-level linguistic pattern is used by the writers in order to cr...
