Abstract: A method of notifying an authorization to shut down completely an aircraft gas turbine engine, the method being applied after detecting that the engine has passed to an idling speed, and including a) an evaluation step of using a value of a first operating parameter of the engine to evaluate a value for a second parameter T45MG wherein a thermal behavior of a part of the engine that might be subjected to coking; b) a comparison step (E30) of comparing the value of the second parameter T45MG with a predefined threshold value T45thresh corresponding to a value of the second parameter that does not lead to coking of the part; and c) a notification step of notifying authorization to shut down completely the engine if the value of the second parameter T45MG is lower than the value of the predefined threshold T45thresh, else reiterating steps a) to c).

Abstract: A system for real time simulation of the environment of an aeroengine includes a digital computer having its inputs switched by a selection module included in the computer either to a respective sensor or else to a substitution digital bus configured to convey substitution digital data generated by a real time simulator.

Abstract: The invention relates to a turbine engine (10), particularly for a helicopter, comprising a gas generator (12) and a free turbine (14) rotated by a gas flow (F) generated by the gas generator. The invention is characterized in that the turbine engine also comprises heating means (26) placed between the gas generator and the free turbine (14), the said heating means (26) being capable of increasing the temperature of the gas flow (f) generated by the gas generator (12) and driving the free turbine.
