GSE56111 is a specialized aerospace engine high-pressure turbine (HPT) blade cleaning GSE (Ground Support Equipment), compliant with AS9100D quality standards and aviation maintenance specifications, designed for large commercial turbofan engines. It is used to remove carbon deposits, oxide scales and other contaminants from HPT rotor blades during on-ground maintenance, which is critical for maintaining the blade's airfoil shape, ensuring the heat dissipation effect of the cooling structure, and avoiding reduced engine thermal efficiency, thrust loss or blade damage caused by contaminants.

Made from high-strength, corrosion-resistant stainless steel and soft cleaning components, it operates stably in -10°C to 115°C ground environments. Weighing 1.1kg with a precision positioning structure, it allows for safe and non-damaging cleaning operation during HPT MRO. It is an essential tool for HPT maintenance.
