GUIDE BLADE FIXTURE IN A FLOW CHANNEL OF AN AIRCRAFT GAS TURBINE

摘要

The fixing device has a slot and hook fixing (40,44) for securing the outer platform (30) of the guide blade segment fitted, between the high pressure and low pressure stages of the aircraft gas turbine, for preventing movement in a radial direction. A pin fitting through the slot and hook connection is also provided for preventing rotation of the guide blade segment. The outer and inner platforms, on opposite sides of the guide blades (15), each have projections (37) cooperating with bearing surfaces (38) of the turbine housing for axial positioning and sealing of the guide blade segment.
