The invention specifically relates to optimizing fuel-injection control. To this end, the driving speeds of apparatuses are adjusted by controlling the speed of the turbine TL according to the power. According to the invention, the method for optimizing the control of a free turbine (TL) power package of an aircraft, provided with a low-pressure body (BP), which supplies power (Pd1, Pd2,...) to apparatuses (E1, E2,...) and which is linked to a high-pressure body (HP), consists of varying the speed (VBP) of the low-pressure body (BP) in order to obtain a minimum speed (VHP) for the high-pressure body (HP), in such a way that the power supplied (Pf) by the apparatuses (E1, E2,...) remains constant. In particular, since the power supplied by the apparatuses (E1, E2,...) is dependent upon the speed at which said apparatuses are driven by the low-pressure body (BP), the speed set point (CBP) of the low-pressure body (BP) of the turbine (TL) is dependent upon the maximum value (Max Vm(i)) of the minimum speeds Vm1, Vm2,...) of the apparatuses (E1, E2,...), enabling the respectively required amounts of power to be obtained in an optimised manner, and upon a positive or zero incrementation added to the speed set point (CBP) of the low-pressure body (BP) in order to minimize the speed (VHP) of the high-pressure body (HP) to the ISO power supply of the apparatuses (E1, E2,...). |
