Selection of parameters for design of engine, turbofan and turbocompressor consisting of turbofan and turbofan mixed flow

Perm National Research Polytechnic University Aerospace Engineering Bulletin
The article considers the features of the selection of the main parameters in the design of turbofan and turbofan-type turbofans, turbofans and turbocompressors of the gas generator in their composition. In addition to the known methods, new methods are proposed for using generalized statistical dependencies, such as the ratio of the diametrical ...

Explainable Remaining Useful Life Prediction Using Interpretable Divisive Feature Clustering

Applied Stochastic Models in Business and Industry, Volume 42, Issue 2, March/April 2026.
ABSTRACT Accurate prediction of remaining useful life (RUL) is critical for effective predictive maintenance. While models like long short‐term memory (LSTM) are effective, they often lack interpretability, even when using explainable artificial intelligence (XAI) methods such as shapley additive explanations (SHAP).

Parametric fault modeling and diagnostics of a turbofan engine [PDF]

Proceedings of the 2004 IEEE International Conference on Control Applications, 2004., 2005
A parametric fault modeling and diagnostics approach of a turbofan engine is presented. The healthy engine model is obtained as a steady state map between input parameters representing engine operating conditions and output parameters governing engine performance characteristics.

Numerical Investigation of Transonic Axial Compressor Rotor With Leading‐Edge Tubercles

Engineering Reports, Volume 8, Issue 3, March 2026.
Amplitude, wavelength, and span‐wise location of the leading‐edge tubercles on a transonic NASA Rotor 37 compressor are numerically optimized. An increase in efficiency by 0.52% compared to the corresponding baseline rotor is observed. The location of the shockwave moves downstream of the rotor with 1.91% higher pressure.

Simulation and Experimental Investigation of Low‐Speed Centrifugal Pump Coupled With Vertical Ultra‐Low‐Head Turbine for Small‐Scale Irrigation

Engineering Reports, Volume 8, Issue 3, March 2026.
From the reviews, a new concept of a low‐speed centrifugal pump (LSCP) driven by a vertical ultra‐low‐head hydro turbine (VULHT) was designed and tested on simulation and physical setup. It was performed with a 1.8 m delivery head, concluding as inefficient. For ultra‐low‐head conditions, different than centrifugal action is recommended.
