The use of soft-computing algorithms in hardware-in-the-loop applications has been investigated. A Proportional-Integral-Derivative (PID) classical controller and a Fuzzy Logic Controller (FLC) were designed and successfully tested on the Turbine Technologies SR-30 turbojet engine for the main-stage operation of the engine. Transfer function model of the plant was obtained using frequency-respo...

This paper introduces a new technique for the verification of both safety and usability requirements for safety-critical interactive systems. This technique uses the model-oriented formal method B and makes use of an hybrid version of the MVC and PAC software architecture models. Our claim is that this technique –that uses proofs obligations– can ensure both usability and safety requirements, f...

In order to provide a basis for the establishment of an applicable strategy for the development of aero-engine thermal cycles, the evolution of compression processes in aero-engine thermal cycles is reviewed in this paper by analyzing the compression requirements for the injection or extraction of energy. It is therefore concluded that the injection of energy in the compression is required for ...

Legacy turbojet engines suffer degradation in performance with usage. Degradations engine components show different observable symptoms based on the control mode of engine. Hence, to accurately model and its degradations, a novel off-design modeling method that considers settings is presented. The improvement due modified scheme presented detail. mathematical used simulation validated by compar...
