Turbine engine servicing tool and method for using thereof

A method for cleaning a portion of a turbine engine comprising:

• inserting a rigidizable guide tube into a borescope port of the turbine engine, wherein the rigidizable guide tube includes a proximal end and a distal end;
• rigidizing the rigidizable guide tube;
• injecting steam into the rigidizable guide tube and into a portion of the turbine engine;
• delivering a fluid through a flexible inner tube disposed within a portion of the rigidizable guide tube to spray a surface of an airfoil, the flexible inner tube including a proximal end and a distal end;
• and
• deploying filaments disposed within the distal end of at least one of the flexible inner tube or the rigidizable guide tube, wherein the filaments are configured to be deployed at least partially out of the distal end of both the flexible inner tube and the rigidizable guide tube towards the surface of the airfoil.

A tool for cleaning an airfoil of a turbine engine comprising:

• a tool body including a proximal end and a distal end and configured to be inserted into a portion of the turbine engine;
• a wand coupled to the distal end of the tool body, the wand including a plurality of orifices disposed along a length of the wand and a rounded tip;
• and
• a fluid delivery supply coupled to the proximal end of the tool body for delivering fluid into the tool body and the wand, wherein the plurality of orifices are configured to spray the fluid onto a surface of the airfoil in a pre-defined spray pattern,
• wherein the plurality of orifices include a hole array and the hole array is arranged such that, when a fluid is passed through the hole array, the pre-defined spray patten is formed, and the pre-defined spray pattern covers at least 50% of a span of the airfoil.
