<p>PROBLEM TO BE SOLVED: To provide case processing which prevents stall of a compressor, facilitates manufacture of parts and reduces manufacturing costs. SOLUTION: A cast assembly (80) for a gas turbine engine compressor comprises an outer platform (70) of a stator (62), a boss (90), an outer shroud (46) of a blade (34) and a slot (106) in the circumferential direction. The boss (90) is formed on the platform (70) and includes a passage (92) having an inlet (94) and an outlet (96). The inlet (94) is arranged within the slot (106) in the circumferential direction, while the outlet (96) is arranged upstream of a front edge (50) of the blade (34). The passage (92) converges to the inside in the circumferential direction when going from the inlet (94) to the outlet (96).</p> |
