Embodiment Construction

[0016] The following detailed description is merely exemplary in nature and is not intended to limit the various embodiments or their application and uses. Furthermore, there is no intention to be bound by any theory presented in the preceding background or the following detailed description.

[0017] Various implementations contemplated herein relate to methods for monitoring engine health of an aircraft having a first engine and a second engine. Exemplary embodiments taught herein provide for obtaining a first turbine gas temperature of a first engine and a second turbine gas temperature of a second engine from a first flight. In an exemplary embodiment, the first turbine gas temperature and the second turbine gas temperature are obtained during takeoff of the aircraft from a runway. Advantageously, this provides consistent engine conditions to achieve the first turbine gas temperature and the second turbine gas temperature. In an exemplary embodiment, a first turbine gas ...

Abstract

Methods for monitoring engine health of an aircraft having a first engine and a second engine are provided. In one example, the method includes obtaining a first turbine gas temperature of the first engine and a second engine turbine gas temperature of the second engine from a first flight. The first turbine gas temperature and the second turbine gas temperature are related to each other to define a first value. The first value is compared to a data set for monitoring the engine health.

Description

technical field [0001] The technical field relates generally to engines, and more particularly to a method for monitoring engine health of a multi-engine aircraft. Background technique [0002] Engines, such as gas turbines, are used to generate thrust for vehicles such as aircraft. It is important to monitor the health of the engine during use in order to troubleshoot potential damage and / or changes in engine performance. Being able to accurately monitor engine health helps to extend the overall life of the engine and improve its efficiency. Engine health may be determined by monitoring parameters of the engine. By monitoring changes in engine parameters throughout the life of the engine, potential engine health issues and / or engine damage can be effectively addressed and / or completely avoided. [0003] Current methods for monitoring the engine health of an aircraft include observing an engine parameter such as turbine gas temperature (TGT) and monitoring how this parame...
