Leitz Reference HP HTA solution

Blisks for aerospace engines have complex geometries that include freeform surfaces and blades with slim profiles and sharp, rounded edges which typically take days to mill. They also need to meet very tight tolerances, making them difficult and time-consuming to inspect.

The Leitz Reference HP HTA solution is purpose-built to overcome the inherent challenges of blisk inspection, using optical measurement for speed and accuracy. The specialised Leitz Reference HP HTA system relies on Hexagon’s HP-O non-contact interferometric laser sensor and specialised Bladed Rotors Measurement software, working with a high performance CMM to deliver precise inspection data with exceptional speed and flexibility.

The HP-O optical sensor’s interferometric system makes it one of the most precise non-contact measurement technologies available. Hexagon’s Bladed Rotors Measurement software meanwhile deploys a combination of parametric techniques, automated path planning for airfoil measurement and collision avoidance to reduce measurement routine creation time by as much as 70%. 

Other advantages of the Leitz Reference HP HTA include the ability to automatically adjust scanning speeds depending on the complexity and importance of the area being measured. 

As a result, the Leitz Reference HP HTA enables manufacturers to increase the speed of blisk inspection by as much as 50% compared to traditional methods, while capturing rich data sets that inform production processes.
