In an arrangement for influencing the radial clearance of the blading of an axial-flow, highly loaded compressor which essentially comprises a rotor (1) equipped with moving blades (2) and a blade carrier (3) which is equipped with guide blades (4) and is hung in a casing (5), the blade carrier (3) has long and narrow mountings (7) for the guide blades (4), at least one hollow space (9) being arranged in the guide-blade roots (8), a hollow space (10) being present in each case in the embedded state in the peripheral direction between the guide-blade root (8), the two mountings (7) for a guide blade (4) and the blade carrier (3), a further hollow space (11) being present in each case in the peripheral direction between the blade carrier (3) and the mountings (7) for two successive guide blades (4), which hollow space (11) is defined by a plurality of segments (12) distributed over the periphery and connected to the guide-blade roots (8), and the hollow spaces (9, 10, 11) being filled with insulating material (15).
An arrangement for influencing radial clearance of blading of an axial-flow, highly loaded compressor comprising a rotor equipped with moving blades and a blade carrier which is equipped with guide blades, the compressor being hung in a casing, wherein the blade carrier has mountings for the guide blades, at least one first hollow space arranged in roots of the guide-blades, at least one second hollow space being disposed in an embedded state in a peripheral direction between the guide-blade roots, the mountings and the blade carrier, at least one third hollow space being disposed in a peripheral direction between the blade carrier and ones of the mountings for two successive ones of the guide blades, the third hollow space being defined by a plurality of segments distributed over a periphery of the blade carrier and connected to the guide-blade roots, and the first, second, and third hollow spaces being filled with insulating material.
