Gas Turbine Compressor Blade Pinning Repairs

Robust low-cost repair for power plant gas turbines

Leonardo DRS’ square base compressor blade modification process prevents wear and tear that can lead to costly power plant gas turbine compressor failures. Loose stator vanes and protruding shims can heighten aerodynamic stimuli that increase deterioration and can cause drastic damage by releasing into the flowstream. 

Our patented solution, a vane/shim pinning system that locks vanes into a robust ring segment, reduces the average harmonic stimuli on the rotor blades and eliminates fretting wear and liberation of vanes and shims. Completed in as little as 12 hours, our process provides a low-cost alternative to replacing expensive gas turbine equipment. 

With hundreds of gas turbines modified to date, there is no doubt our process is proven reliable. Contact our blade modification specialists to help you complete maintenance cycles on time and on budget and keep your expensive equipment running when time is of the essence.
