AIRCRAFT ELECTRICAL SYSTEM OPERATING METHOD |
| 摘要 |
A method of controlling an aircraft electrical system (40). The electrical system (40) comprises an alternating current electrical machine (56, 58) comprising a plurality of phases, each phase having a power rating, the electrical machine (56, 58) being configured to operate on failure of one or more phases. The method comprises: determining a power requirement; sensing a fault of one or more phases of the electrical machine (56, 58), and controlling the electrical machine (56, 58) to operate in a fault condition, in which the remaining phases of the electrical machine (56, 58) provide the electrical power requirement; and providing an overrating signal to a flight computer (66) of the aircraft (2) where the power provided by each phase exceeds the power rating of the respective phase. |

1. A method of controlling an aircraft electrical system, the electrical system comprising: an alternating current electrical machine comprising a plurality of electrical phases, each phase having a power rating, the electrical machine being configured to operate on failure of one or more phases; the method comprising:
determining a power requirement; sensing a fault of one or more phases of the electrical machine, and, where a fault is sensed: controlling the electrical machine to operate in a fault condition, in which the non-faulty phases of the electrical machine provide the electrical power requirement; and providing an overrating signal to a flight computer of the aircraft where the power provided by each phase exceeds the power rating of the respective phase. |
