Physics-Based Prognostics for LCF Crack Nucleation Life of IMI 685 Aero-engine Compressor Disc
A life cycle management-expert system (LCM-ES) framework is employed in this work for physics-based prognostics of a compressor disc. The modeling approach involves the integration of both global behavior and localized response of component at the microstructural level. This paper presents the results of a low cycle fatigue (LCF) case study for a near alpha titanium alloy (IMI 685) high pressur...
متن کاملStall Vortex Shedding over a Compressor Cascade (RESEARCH NOTE)
The unstable flow with rotating-stall-like (RS) effects in a rotor-cascade of an axial compressor was numerically investigated. The RS was captured with the reduction in mass flow rate and increasing of exit static pressure with respect to design operating condition of the single rotor. The oscillatory velocity traces during the stall propagation showed that the RS vortices repeat periodically,...

متن کاملSimplified Compressor Performance Scaling
This paper presents an analytical method adopted to scale perfonnance data from one machine to another within the same general family type using simplified assumptions. This is used for a fast and accurate performance prediction before committing to costly test procedures. For example, the capacity variation between scaled machines is first broken up into leakage effects, pressure drop effects,...
متن کاملA cascade thermoacoustic engine.
A cascade thermoacoustic engine is described, consisting of one standing-wave stage plus two traveling-wave stages in series. Most of the acoustic power is produced in the efficient traveling-wave stages. The straight-line series configuration is easy to build and allows no Gedeon streaming. The engine delivers up to 2 kW of acoustic power, with an efficiency (the ratio of acoustic power to hea...
