Wear Prognostic on Turbofan Engines

Annual Conference of the PHM Society, 2013
One of the most evident characteristic of wear for a turbofan engine is the exhaust gas temperature (EGT). It seems clear that this temperature increases when some carbon deposits on the turbine, when the compressor efficiency diminishes so the fuel flow should increase to produce the same amount of thrust, or even when some ...

Robust monitoring of turbofan sensors

2014 IEEE Aerospace Conference, 2014
Bench development tests of new turbofan engines make an important use of sensor measurements to help engineers understand the behavior of new components design. Such tests are expensive and may be completely compromised if any measurement is missing.

Compound cycle turbofan engine

19th Joint Propulsion Conference, 1983
The paper discusses the design and development of critical technologies for a "near-adiabatic" compound cycle turbofan engine (CCTE). The concept involves replacing the combustor of a conventional turbofan engine with a highly supercharged, high-speed, two-stroke, direct-injected diesel core. Primary emphasis was on reducing specific fuel consumption t

Variable Bypass Turbofan

2013
This study was conducted to investigate the effect of a variable bypass on the operation and performance of a turbofan engine. The goal was to establish the viability of such an engine, in the context of being able to provide an aircraft, so equipped, with variable performance that could be altered to suit different operational scenarios.

Large turbofans to the year 2000

The Aeronautical Journal, 1984
The recognition of the political importance of energy supply, inefficient energy usage and its adverse ecological impact combined to produce rapidly inflating energy prices which in turn contributed to an industrial slump. With this platform of a decade of uncertainty, predicting future requirements is, to say the least, somewhat problematical.
