HNN-based generalized predictive control for turbofan engine direct performance optimization
, 2021The aero-engine performance optimization control is to find the appropriate control variables to maximize or minimize the comprehensive index of one or more performance parameters while ensuring its safe operation. Traditional performance seeking control

A recent two‐line news item in the International Herald Tribune highlighted an important aspect of Russia's interest in developing cryogenic‐fuelled aircraft. The item read simply “The airport in Vladivostok, in far eastern Russia, closed down on Tuesday because it had run out of fuel.” The air routes to Vladivostok from Moscow and other major Russian ...

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 ...

Thermodynamic optimization of the turbofan cycle
Aircraft Engineering and Aerospace Technology, 2006Purpose – To develop and find the effect of combination of four cycle design variables that minimizes the specific fuel consumption (sfc) of a turbofan engine.Design/methodology/approach – After choosing the four variables, namely bypass ratio (B), fan pressure ratio, overall pressure ratio, and turbine inlet temperature (T04), first the sfc was ...

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 ...

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
