System for real time simulation of the environment of an aeroengine

A system comprising:

• at least one digital computer embedded in an aircraft and configured to control an engine in the aircraft, each digital computer comprising:
• at least one input configured to receive data representative of a state of a sensor of the engine or of the aircraft;
• at least one output configured to be connected to at least one actuator of the engine or of the aircraft;
• and
• a regulation module configured to generate at least one command and send the at least one command via the output to the at least one actuator as a function of data received by at least one input;
• the system further comprising:
• a selection module included in the at least one digital computer and configured to switch the input either to the sensor or else to a substitution bus as a function of an instruction from an operator;
• a real time simulator, embedded in the aircraft, for simulating at least some of an environment of the engine and of the aircraft, the simulator comprising:
• a digital output configured to send at least one substitution item of digital data generated by the real time simulator over the substitution bus to the input of the at least one digital computer, wherein the regulation module is configured to generate and send the at least one command via the at least one output to the at least one actuator as a function of the at least one substitution item of digital data;
• and
• a digital input connected to the at least one output of the digital computer and configured to receive the at least one command issued by the at least one digital computer, the real time simulator configured to simulate reaction of the engine and of the aircraft to the command;
• and
• a verification module included in the at least one digital computer, configured to implement a verification procedure for preventing the at least one input of the digital computer from being switched to the substitution bus by the selection module when the aircraft is in flight.
