98V27008001000 is a specialized aerospace engine variable stator vane (VSV) system performance testing GSE (Ground Support Equipment), compliant with AS9100D quality standards and FAA/EASA MRO regulations, designed for CFM56 series turbofan engines. It is used to test the adjustment accuracy, response speed and working stability of the VSV system during on-ground maintenance, which is critical for ensuring the system can adjust the angle of HPC stator vanes according to engine operating conditions, optimizing air compression efficiency and avoiding surge or stall of the compressor.

Made from high-strength engineering plastic and precision mechanical sensing components, it operates stably in -15°C to 100°C ground environments. Weighing 0.7kg with a quick-connect control interface, it allows for fast and accurate testing during VSV system MRO. It is an essential tool for engine compressor maintenance.
