856A1802G02 is a precision aerospace fixture compliant with AS9100D quality standards and FAA/EASA regulations, dedicated to aircraft engine compressor section maintenance.It serves as a compressor stator vane positioning fixture, specialized in accurate mounting and alignment of compressor stator vanes during MRO disassembly, repair and reassembly. It ensures precise vane angle, spacing and concentricity tolerances, eliminates installation deviation, prevents airflow disturbance and pressure loss in the compressor section, avoids uneven load distribution on rotor blades under high-speed rotation, and maintains optimal compression efficiency across all engine operating conditions.Made of high-strength heat-resistant alloy steel, it resists high temperature and mechanical impact, working stably at -55℃ to 330℃. Weighing 1.3kg, it features secure locking mechanisms and calibrated locating notches, enabling efficient, standardized assembly with consistent accuracy. It is a vital tool to guarantee compressor aerodynamic integrity and overall engine operational safety, efficiency and service life.
