Modified Brayton Cycle for Turbofans
Volume 2: Combustion, Fuels, and Emissions; Renewable Energy: Solar and Wind; Inlets and Exhausts; Emerging Technologies: Hybrid Electric Propulsion and Alternate Power Generation; GT Operation and Maintenance; Materials and Manufacturing (Including Coatings, Composites, CMCs, Additive Manufacturing); Analytics and Digital Solutions for Gas Turbines/Rotating Machinery, 2019Abstract In the present study, a design point analysis of twin-spool turbofan engines is carried out, considering fuel injection of Aviation Turbine Fuel (ATF) in the initial stages of the compressor instead of combustor The two-phase compression brings about intercooling in the modified Brayton cycle, by injecting the atomized fuel ...

Compound cycle turbofan engine
19th Joint Propulsion Conference, 1983The 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

Wear Prognostic on Turbofan Engines
Annual Conference of the PHM Society, 2013One 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 ...

Large turbofans to the year 2000
The Aeronautical Journal, 1984The 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.

Water-Augmented Turbofan Engine
Journal of Hydronautics, 1968This paper describes a novel lightweight propulsion scheme for use in high-speed ships in which large amounts of water are injected into the fan discharge duct of an aircraft- type turbofan engine. Theoretical design and off-design performance for this water-augmented turbofan engine show that dry thrust theoretically can be augmented 380% at 25 knots ...

Robust monitoring of turbofan sensors
2014 IEEE Aerospace Conference, 2014Bench 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.
