Telford-based Hexagon Manufacturing Intelligence (www.hexagonmi.com) has launched its Global Advantage HTA (High Throughput and Accuracy), an enhanced metrology solution for compressor blades.

According to the company, the system is tailored to provide a step-change improvement in measurement throughput, while delivering high-density measurement data for enhanced aerofoil geometry analysis.

The Global Advantage HTA platform is based on Hexagon’s HP-O Multi optical-scanning-probe technology.

Featuring frequency-modulated laser interferometry technology, the device provides rapid non-contact scanning at ‘single-micron uncertainty’ to verify blade characteristics, including aerofoil, platform, root, shroud and other features.

Highly polished blade surfaces are easily measured, says the company, without the need for the secondary coating and cleaning operations necessary for many non-contact technologies.

Using BladeSmart inspection software from Hexagon, the Global Advantage HTA includes an execution command library containing aerofoil, platform and root geometry methods, allowing faster creation and deployment of measurement programs.
