This paper presents a comprehensive study of model-based fault diagnosis (FD) and fault-tolerant control (FTC) scheme for sensor actuator faults turbojet engines. For FD, an unbiased estimation with modified Kalman filter (KF) was developed. two approaches, the generalized likelihood ratio robust KF pseudo model KF, were investigated in comparative study. detection isolation, test statistics ar...

A turboprop engine is a hybrid that delivers thrust or jet and also drives the propeller. This basically similar to turbojet except turbine works through main shaft which connected reduction gear rotate propeller in front of engine. research was conducted determine development performance thermodynamic analysis so as know value each parameter on has been developing for 20 50 years with differen...

This paper presents a study regarding the noise reduction of turbojet engine, in particular jet micro engine. The results measurement campaign are presented followed by performances analysis which is based on measured data test bench. Within tests, beside baseline nozzle other two nozzles with chevrons were tested and evaluated. First type foreseen eight triangular chevrons, length being L = 10...
