Abstract
The invention relates to a method for regulating an acceleration of a turbomachine, the turbomachine comprising a combustion chamber, a high-pressure turbine located downstream of the combustion chamber and which drives a high-pressure shaft in rotation, and a low-pressure turbine located downstream of the high-pressure turbine and which drives a low-pressure shaft in rotation, characterized in that the method comprises the following steps: injecting mechanical power onto the high-pressure shaft until a speed of the high-pressure shaft attains a target value, then extracting mechanical power from the high-pressure shaft so as to maintain the speed at the target value.
