Self-tuning aircraft engine models can be applied for control and health management applications. The self-tuning feature of these models minimizes the mismatch between any given engine and the underlying engineering model describing an engine family. This paper provides details of the construction of a self-tuning engine model centered on a piecewise linear Kalman filter design. Starting from ...

In this paper are presented the results obtained by modelling and simulation of the combustion in a turbojet engine. The study of the mathematical model represented by the equations which described the combustion process was made by using the software FLUENT 6.1. The paper is focused on the establishment of the link between the control laws of the turbojet engine (whose main parameter is the fu...

With the increasing thrust-to-weight ratio of modern aeroengines and widespread adoption thin-walled casing, impact coupling vibration effect between rotor stator on critical speed, rotor–stator mode shape coordination, response characteristics whole engine have become increasingly prominent. However, vibrational design whole-engine has thus far relied human experience, revealing a need for stu...

Aircraft emissions are a significant source of pollution and are closely related to engine fuel burn. The onboard Flight Data Recorder (FDR) is an accurate source of information as it logs operational aircraft data in situ. The main objective of this paper is the visualization and exploration of data from the FDR. The Airbus A330 223 is used to study the variation of normalized engine performan...

The article proposes an approach based on deep and machine learning models to predict a component failure as enhancement of condition maintenance scheme turbofan engine reviews currently used prognostics approaches in the aviation industry. Component degradation scale representing its life consumption is proposed such collected data are combined with engines sensors environmental data. With use...
