This versatile laser scan measuring machines series are suitable for a wide variety of blade airfoil measuring applications. The system’s features provide fast scanning time, high accuracy and reliability measuring all types of jet engine blades including fan, rotor and vane parts.
The Metroptic MARS software provides full data of airfoil parameters for each blade section and calculates all intersection parameters. The graphic interface supports real time demonstration of measured blade characteristics and operational capability. The measuring machine is user-friendly, robust and reliable.
