New LGWAS LiniGage System

It shares the same Features and Benefits as the new recently introduced Capacitec LiniGage seen on the above table except for the custom multi-rotor, multi-engine HPC/HPT air gap measurements feature.

The Capacitec LiniGage is an Aircraft Engine Rotor Eccentricity Realignment System that is used to set the concentricity of engine rotor assemblies such as in the HPC and HPT sections after assembly. A 0.220” (5.6mm) non-contact displacement sensor is temporarily attached to the tip of one of the blades at an air gap of approximately 0.040” (1mm) to the inside diameter of the casing. A lead is typically wrapped two or three times around the circumference of the rotor and exits the engine casing through a convenient bore scope hole and connected to the LiniGage electronics. The rotor is turned 360° allowing the sensor to measure the air gap between the blade tip and the engine casing inside circumference. The LiniGage custom software takes the air gap values and polar plots the circumferential blade gap and calculates the eccentricity magnitude with its resultant angle. An out of spec eccentricity plot then allows the engine rebuild technician to easily identify where to make casing positional adjustments to normalize the casing position for the best eccentricity and run out values. These actual values are compared to customer limits creating a permanent quality record.
