چکیده
• The gas turbine model is validated by a well-used commercial software. An adapted sequential method established for fault diagnosis of aero engines. Effect heat soakage considered in under dynamic conditions. economic impact our assessed hydrogen powered flights. could diagnose faults successfully states. At present, engine mainly based on the steady-state condition at cruise phase, and path parameters entire flight process are not effectively used. same time, high quality monitoring measurements always available as result accuracy might be affected. There recognized need real-time performance engines operating transient conditions, which can improve their condition-based maintenance. Recent studies have demonstrated capability model-based diagnostic to predict accurately efficiently degradation industrial turbines Nevertheless, incorporating data detection that operate conditions more challenging task. primary objective this study investigate when it applied while there variation bypass ratio effects taken into consideration. This provides novel approach quantifying component degradation, such fouling erosion, using an version method. research presented here confirms proposed both real-time. In addition, fuel cost payload revenue evaluated investigation hydrogen. promising results where maximum prediction errors steady state less than 0.006% 0.016%, respectively. comparison benchmark revealed 15% improvement great benefit considering attributed reach up $702,585 6000 cycles aircraft fleet. opportunity understanding order reliability, availability, efficiency online health monitoring.

Influence of unsuitable operational conditions on the transient performance of a small hydrogen liquefier
Joule-Thomson cooling systems are used in refrigeration processes such as cryogenic gas liquefaction. Although extensive studies have been carried out by researchers, most of them include cryogenic heat exchangers and their associated fields. In the current study, an attempt was made to indicate the effect of using inappropriate operational conditions in a cryogenic Joule-Thomson cooling system...

متن کاملTitanium in Aero Engines
The talk is intended to give an overview on the necessity and future trends of titanium parts in aero-engine applications. It will serve as a link to the presentations given in the special session aero-engines. It is well known that for aero-engines the combination of a very high loading by temperature and stress together with extremely high safety levels are determining the choice of materials...
متن کاملA Dynamic Decoupling Method for Controlling High Performance Turbofan Engines
A new dynamic decoupling method is proposed for controlling complex uncertain systems. Where mathematical modeling is often tedious or inaccurate, the new method uses an unknown input observer (UIO) to estimate and cancel dynamic information in real time. Consequently, controller design and tuning become transparent as the number of required model parameters is reduced. A realistic turbofan sim...
