Fan blades are literally the driving force of the modern jet turbine; 90% of the engine’s propulsion is generated by 20-30 of them at the front of the engine. High accuracy and repeatable measurements are required in the structure of fan blades, as they ensure peak performance of an engine. With this in mind, fan blades are designed to satisfy three criteria: engine efficiency, engine durability and thrust capacity.
ATOS, GOM’s three-in-one powerhouse solution, is used throughout the entire fan blade life cycle to help manufacture high-quality fan blades for maximum performance and accuracy, such as in-process checking, forging dies, final inspection, maintenance and repair workshops.
Fan blade designs have evolved along with aerospace technology, becoming more geometrically challenging while incorporating more curvatures, larger dimensions and weight variations.
Fan blades often have varying thicknesses, a lack of symmetry, complex measurement demands and in their most modern form they are made of carbon fiber materials. These complexities create challenges in traditional inspection processes that reveal the limited capabilities of CMMs.
ATOS technology combines high accuracy with full-field data to evaluate aerodynamic efficiency and reduced production times. From the root form to leading and trailing edge geometries, ATOS technology uses Blue Light Technology and GOM Inspect software to evaluate even the most complex blade designs.
Fan blade innovations plus the growing competition in the aero engine market have increased the demand for increased turbine performance and volumes with shorter production times. This pressure on manufacturing processes leads OEMs to search for measurement solutions that outpace CMMs to efficiently keep up with demand. Automated systems are key and enable manufacturers to measure critical surfaces on fan blades that typically take more time, such as trailing edge radii or the root block. Utilizing this kind of technology alongside user-friendly software is what ATOS systems are built for.
Maintenance and repair are enormous cost factors throughout the entire product life cycle. Additionally, time is critical when it comes to getting fan blades back in the air. OEMs need high-speed measuring systems and software that can anticipate service, failures and overhauls now more than ever.
From A-Checks to D-Checks, ATOS technology supports wear and tear analyses as well as the planning and control of repair jobs such as:
