Larger blade sizes, new materials and changing designs make the need for structural testing more critical than ever. Moogapplies experience in听aircraft testing听and expertise in听wind power听to offer a unique approach to blade testing.

Using hydraulic actuators/electrical winches and our high-performance test systems, OEMs have a flexible approach to structural testing that can grow and change as their designs change over time, taking into account different parameters such as wind strength, blade characteristics, blade-tip deflection and profile.

Our听test controllers听for blade testing can perform static and dynamic tests. The Moogtest controller system affords straightforward test setup and user-friendly analysis of the measured data.

Case Study

When a leading wind power equipment provider in India required precision blade test systems for its latest designs, Moogdelivered a solution incorporating leading edge design and unsurpassed performance.

The Challenge
Provide equipment that delivers precise and thorough testing of the company鈥檚 latest blade designs to help determine optimal benefits. The system should be flexible to perform a full range of dynamic and static blade tests for sizes up to 60 meters long.

The Solution
Moogdesigned and installed a system to perform two types of structural tests on different blades.

The first is a 6-channel static test system comprised of 6 electrical winches that pull the blade via 6 mechanical frames and height-adjustable pulleys. Loads up to 200 kN can be applied.

The second is a 2-channel dynamic test system consisting of two long-stroke hydraulic actuators equipped with a displacement transducer and load cell using MoogServovalve Technology.

The system uses the MoogTest Controller, a fixture in leading test labs worldwide.

With the test systems in place, the customer can take advantage of robust test procedures in both static and dynamic platforms, as well as ensuring simple set-up and test procedures for their newest blade designs.
