Optical Measurement of Turbine Blades

Precision and performance: a new standard for turbine blade inspection

In the safety critical world of aerospace and energy, the performance and safety of turbine blades is critical. Bruker Alicona have partnered with industry leaders to develop optical inspection tools, to provide rapid, non-contact measurement solutions delivering comprehensive 3D analysis using focus variation.

Using a single measurement sensor, with a single, high-precision optical sensor either on a measurement system, or on a cobot system our Alicona systems are able to:

Validate critical components: Confidently inspect fir tree geometry and surface finish.
Perfect the aerofoil: Measure leading and trailing edge radii, deviation of form, and profile twists with micron-level precision.
Assess surface integrity: Measure profile (Ra) and areal roughness(Sa) to measure surface finish of material and coatings.
Measure the smallest flaws: Quickly measure surface defects that could compromise performance.
Master the intricacies of cooling hole geometry: Accurately measure the form, position, and diameter of these vital features to ensure optimal thermal management.

Precision and performance: a new standard for turbine blade inspection

A future-proof turbine blade inspection solution

The Alicona G6 with Real 3D rotation unit is ideal for the rapid measurement of the geometry and surface roughness of high value components.

Recent developments include

Vertical Focus Probing – the optical probing and measurement of holes (such as cooling holes) and vertical flanks
SmartFlash – designed to ensure high resolution measurement of smooth, reflective and highly polished surfaces
5 axes metrology – the high precision rotation unit allows measurement of complex geometries, enabling capture of GD&T data and roughness parameters on an entire object

The G6 is in regular use at several European facilities measuring turbine blades both when manufactured and when removed for evaluation at end of life.

Alicona InfiniteFocus G6

The G6 being the latest in a long line of products from Alicona, uses focus variation coupled with a sample mount capable of positioning the sample in 3 dimensions. It will measure to sub micron accuracy, combining the functionality of a roughness measuring system with a coordinate measuring machine.

Trusted by the World's Most Innovative Brands

The Optimax team with their extensive knowledge and expertise, have proven themselves to be the ideal partner for independent, candid advice. They are a company we can trust to support our metrology and visual inspection needs whether we are purchasing equipment or developing specific metrology instruments for our applications. Their experience and methodical attention to detail mean the outcomes we achieve support our testing requirements.

Dr Andrew Johnson, Assistant Director, RandA

Optimax are a trusted partner! We have been working in partnership with Optimax for several years, to supply us with inspection solutions, service, and onsite calibration to UKAS standards. Their knowledge and expertise is exceptional, they provide honest, independent advice. Optimax are quick to provide options and solutions for our inspection requirements. They work hard to deliver a solution that 100% fits the application rather than just supplying a product. Optimax work with us to ensure we achieve our inspection objectives – they are one of the first companies I turn to.

Bruce Daggett, Senior Aerospace Weston, Inspection Team Leader

For over 14 years Optimax has been providing us with inspection equipment, service and most importantly expertise. We need suppliers that can go the extra mile in looking specifically at our application and then providing a suitable and sometimes bespoke solution, and this is where Optimax have really made a difference

John Harris, Director, Nevo Developments

Optimax have an extensive product range that was very attractive to us. They took the time to understand my requirements and align a solution that fitted into my manufacturing processes. They were very knowledgeable and friendly, I found the virtual demonstration extremely helpful. The outcome of the project has been very successful and performs above expectations. I would definitely recommend Optimax.
