<p>#CMT# #/CMT# The method involves determining a value illustrating a thermo-mechanical condition (ET) of a turbine engine to illustrate expansion of an element of the engine based on thermal conditions, from measurement of exhaust or turbine gas temperature (T). The determined value is compared with threshold values (S1, S2). Indications (I1-I3) relating to operation of the engine are displayed based on comparison result by a displaying unit on a viewing screen of an aircraft cockpit, where the indications relate to a damage risk for the engine, a lock risk for the engine and/or an operational procedure. #CMT# : #/CMT# Independent claims are also included for the following: (1) a device for providing assistance to automatically monitor a turbine engine of an aircraft (2) an aircraft system for an aircraft provided with a set of turbine engines. #CMT#USE : #/CMT# Method for providing assistance to monitor a turbine engine e.g. turbojet or turbopropeller, of an aircraft (claimed) such as civil transport plane. #CMT#ADVANTAGE : #/CMT# The indications relating to the damage risk for the turbine engine, the lock risk for the engine and/or the operational procedure are displayed on the viewing screen of the aircraft cockpit, so that a pilot is informed about actions to be implemented, thus enabling a crew member to quickly interpret the condition of the turbine engine by observing the displayed indications, and hence enabling the crew member to take suitable decisions. The indications are repeatedly updated to provide information illustrating the current situation to the crew member. The method enables the pilot to optimize the use of the turbine engines on the ground in the running phase by shutting down one or several turbine engines without causing any damage, thus optimizing fuel consumption in the running phase to achieve cost savings, and reducing thermomechanical stresses on constitutive elements of the turbine engine to extend the lifetime of turbine or compressor disks. #CMT#DESCRIPTION OF DRAWINGS : #/CMT# The drawing shows a graph illustrating the evolution in the thermomechanical condition of a turbine as a function of temperature over time. ET : Thermo-mechanical condition I1-I3 : Indications relating to operation of turbine engine S1, S2 : Threshold values T : Exhaust or turbine gas temperature TR : Duration.</p> |
