METHOD FOR MONITORING OPERATING STATE OF SYSTEM FOR POSITIONING VARIABLE-GEOMETRY MEMBERS OF TURBOMACHINE

The invention concerns a method for monitoring the operating state of a system for positioning variable-geometry members (18) of a turbomachine (10). The members (18) is configured to travel over an operating area comprising a first position P1 and a second position P2, and the method comprises the...

Zusammenfassung:	The invention concerns a method for monitoring the operating state of a system for positioning variable-geometry members (18) of a turbomachine (10). The members (18) is configured to travel over an operating area comprising a first position P1 and a second position P2, and the method comprises the steps: (E23) determining a first pivoting speed V1 from the first position P1 to the second position P2;(E25) determining a second pivoting speed from the second position P2 to the first position P1; and (E26) determining an anomaly in the operation of the system for positioning the members (18) if the first speed V1 is lower than a first determined speed threshold and/or if the second speed V2 is lower than a second determined speed threshold. 本发明涉及一种用于监测用于对涡轮机(10)的可变几何构件(18)进行定位的系统的运行状态的方法，该构件(18)被配置为在包括第一位置P1和第二位置P2的运行区域内行进，该方法包括以下步骤：-(E23)确定从第一位置P1到第二位置P2的第一枢转速度V1；-(E25)确定从第二位置P2到第一位置P1的第二枢转速度；以及-(E26)如果第一速度V1小于第一确定速度阈值和/或如果第二速度V2小于第二确定速度阈值，则确定用于对构件(18)进行定位的系统在运行中有异常。
