856A1828G01 is a precision aerospace fixture compliant with AS9100D quality standards and FAA/EASA regulations, dedicated to aircraft engine turbine section maintenance.It serves as a turbine blade positioning fixture, specialized in accurate fixing and aligning turbine blades during MRO disassembly, inspection, repair and reassembly. It ensures strict blade pitch, angle and tip clearance accuracy, avoids misalignment-induced rotor imbalance, abnormal vibration, blade rub-impact and local overheating, which is critical for stable turbine operation at high rotational speeds and extreme temperatures.Made of high-strength heat-resistant alloy steel, it resists high temperature and deformation, working stably at -55℃ to 330℃. Weighing 1.0kg, it features a quick-clamp structure for efficient operation and precise locating pins for reliable positioning. It is a vital tool to guarantee turbine assembly precision, optimize aerodynamic performance and ensure overall engine operational safety and stability.
