low bypass turbofan enginemetallurgical investigationsleading edgeFailure of low pressure turbine rotor blade in a low bypass turbofan engine is analyzed to determine its root cause. Forensic and metallurgical investigations are carried out on the blade failed. The failure has originated from the leading...
The high sensitivity of receptors to adequate stimulation is measured by the absolute threshold or minimum intensity of stimulation capable of exciting the receptors. Thus, five to seven quanta of light striking the eye’s receptors cause a sensation of light, whereas a single quantum is sufficient...
Various defects reported during service of a military low bypass turbofan engine over a period are highlighted and their trend is presented in this paper. Causes of these defects are investigated and remedial measures are incorporated to address these issues. Proper maintenance of the engines at ...
LOWBYPASSRATIOOFF-DESIGNCOMPONENTMATCHINGOOPperformanceIn order to study component matching which exists in off-design situation at the initial design stage of turbine engine,by establishing performance analysis model of low bypass ratio mixed flow turbofan engine and components characteristic data,and by ...
Therefore, to evaluate the overall combustion performance of a low bypass ratio turbofan engine, turbulent combustion was modeled and analyzed using computational fluid dynamics (CFD) technique. Analysis was carried out to simulate afterburner functioning at engine ground run (standard sea level ...
A low bypass ratio mixed flow turbofan engine was modeled, and key parts of a fighter mission were simulated. The investigation shows how power extraction from the high-pressure turbine affects performance of a military engine in different parts of a mission within the flight envelo...
