Mode transition control is a critical issue of Turbine-Based-Combined Cycle (TBCC) engines
when the primary thrust providers change from gas turbine engines to ramjets/scramjets …

The accuracy of component maps significantly affects gas turbine performance simulation
results. Unfortunately, the information in component maps is usually insufficient to …

Obtaining accurate components' characteristic maps has great significant for gas-turbine
operating optimization and gas-path fault diagnosis. A common approach is to modify the …

The present work is a contribution to understanding the windmilling operation of low-speed
fans. Such an operating situation is described in the literature, but the context (mainly …

Prediction of aero-engine performance in the sub-idle regime is becoming increasingly
important. Performance prediction tools rely on component maps to enable system-level …

Improving efficiency, reliability and availability of gas turbines have become more than ever
one of the main areas of interest in gas turbine research. This is mainly due to the stringent …

Gas turbine performance models typically rely on component maps to characterize engine
component performance throughout the operational regime. For the sub-idle case, the lack …

This paper develops a new method for the calculation of low speed characteristic of
compressor. Considering of the compressibility of the air, the low speed index of pump …

Several techniques have come about for the mathematical extrapolation of compressor
maps from the idle region down to zero speed. Relatively little work has been done on …
