AIRCRAFT EQUIPPED WITH A DEVICE FOR MONITORING THE ELECTRONIC MANAGEMENT OF THE ENGINES

摘要

An aircraft comprising at least two engines and an electronic management arrangement comprising a control computer for each engine, each computer being configured for monitoring the operation of its associated engine and for activating an engine protection mode when the engine operation exceeds predetermined operational limits The electronic management arrangement furthermore comprises an engine interface device to which the control computers are connected, the device prohibiting the activation of a protection mode by a control computer when a protection mode is activated by another control computer. A monitoring device is connected to the control computers and receives an information signal from each control computer to indicate if a protection mode is activated and transmits, in the case where a protection mode is activated on at least two engines, a control signal to the control computer having last activated a protection mode to cancel the activation of the protection mode.

主权项

1. An aircraft comprising:
at least two engines and electronic management means comprising control computers, one for each engine, each computer being configured for monitoring the operation of the engine with which it is associated and for activating a protection mode of the engine when the operation of the engine exceeds predetermined operational limits, the protection mode being of two types, one being a minor protection mode according to which the thrust that an engine can provide is less than its maximum thrust, and the other being a major protection mode according to which the engine is shut down, an engine interface device to which the control computers are connected, the device being configured for prohibiting the activation of a protection mode by a control computer when a protection mode is activated by another control computer, and a monitoring device connected to the control computers, the device configured to receive an information signal from each of the control computers in order to indicate if a protection mode is activated and to transmit, in the case where a protection mode is activated on more than one engine, a control signal to the control computer having last activated a protection mode in order to cancel the activation of the protection mode.
