Journal of Function Spaces, Volume 2021, Issue 1, 2021., 2021 The twin‐spool turbofan engine is an important component of almost every modern aircraft. Fault detection at an early stage can improve engine performance and health. The current research is based on the construction of an inference system for fault diagnosis in a generalized fuzzy environment.

The paper highlights significance of the interturbine transition duct as part of the high pressure and low pressure turbine spool. The correlations have been suggested allowing us to estimate variation of the average cross section flow swirl while its passing the interturbine transition duct.

Abstract The predictive accuracy of the lattice-Boltzmann method very large eddy simulation (LBM-VLES) approach was evaluated for a 1-1/2 stage transonic turbine with an aggressive interturbine transition duct (ITD). As the geometry was not publicly available, efforts were undertaken to reverse engineer the geometry of the transonic high
