Method for checking the maximum power available to different members of a propulsion chain of an aircraft
A method for checking the maximum power available to members of a propulsion system of an aircraft includes first members that are sized to compensate for the failure of second members of the propulsion system by delivering a maximum power to keep the aircraft in a safe operating range. The method includes the following steps for each of the first members: placing the first member in a state that is substantially equal to a maximum power state; adjusting the power delivered by the second member working in synergy with the first member so that the first member and the second member contribute to delivering the power required for the aircraft in the flight phase; determining the power delivered by the first member placed in the maximum power state; from the determined power, deducing information relating to the maximum power available to the first member.
1 . A method for checking a maximum power available to members of a propulsion system of an aircraft comprising first members sized to compensate for a failure of second members of the propulsion system by delivering a maximum power to keep the aircraft in a safe operating range, the first members comprising an electrical power source, a member for distributing the electric power delivered by the electrical power source and a member for transforming the power delivered by the distribution member, the method comprising the following steps for each of the first members:
placing the first member in a state that is substantially equal to a maximum power state;
adjusting a power delivered by the second member working in synergy with the first member, so that the first member and the second member contribute to delivering the power required for the aircraft in the flight phase;
determining a power delivered by the first member placed in the maximum power state;
from the determined power, deducing information relating to the maximum power available to the first member.
2 . The method according to claim 1 , comprising the following additional steps:
determining a threshold power corresponding to a minimum power to be reached by the first member placed in the maximum power state, and
comparing the power delivered by the first member with the threshold power.
3 . The method according to claim 1 , automatically interrupted when at least one of the following conditions is fulfilled:
the power delivered by the first member placed in the maximum power state is less than or equal to a threshold power
a parameter of the first member placed in the maximum power state is less or greater than a predetermined threshold,
a failure is detected on the first member placed in the maximum power state of take-off.
4 . The method according to claim 1 , further comprising the step of collecting data from the first members during the other steps, and of enriching a model enabling a predictive analysis of needs for maintenance actions for each of said first members.
5 . A computer program product on a non-transitory storage medium comprising instructions for the execution of the method according to claim 1 when this program is executed by a processor.
6 . A control device comprising a computer configured to implement the method according to claim 1 .
7 . An assembly comprising at least two chains of members configured to work in synergy and together deliver a power required to an aircraft in a flight phase, wherein the aircraft comprises the control device according to claim 6 .
8 . An aircraft comprising at least two chains of members configured to work in synergy and together deliver a power required to an aircraft in a flight phase, wherein the aircraft comprises a computer configured to implement the method according to claim 1 .
