ABSTRACT:
In a supersonic area, on a leading edge (2) of a compressor blade (1) for a gas turbine engine, a replaceable, longitudinally elastically deformable leading edge rail (7) with slender tip (11) and limited weight is positively held in a locating groove (3) and at a stop (6) and elastically locked by the curved blade form. While the maintenance effort is reduced, safe operation and long service life of the compressor (fan) are ensured.
