FeatureSealing system proven to have low-external leakage, minimal friction, and reduced contamination • LVDT adjustment feature which guarantees actuator-LVDT assembly and interface accuracy
The function of the core inlet guide vane (CIGV) actuator is to mechanically position the inlet guide vanes when commanded by the full authority digital engine control (FADEC). During normal operation, the actuators are modulated according to the FADEC based upon feedback from the master’s linear variable differential transformer (LVDT) signal. Typically, there are two types of CIGV actuators, master and slave. The master is the only one that contains an electro hydraulic servo valve (EHSV) and a LVDT position sensor provides electrical feedback to the FADEC.
