FIXING METHOD FOR A TIP WINGLET AND REDUCED TIP LEAKAGE BLADE

摘要

Reducing the tip leakage for an existing compressor or turbine blade (10), including internally cooled blades, can be achieved by retrofitted the blade with a tip leakage-reducing device in the form of a winglet (12). The winglet (12) can be fixed onto the tip portion by bonding the winglet onto the face or faces of the blade by a key and slot arrangement.
