Abstract
Abstract A drum-type rotor for an axial flow compressor comprises a number of abutting annular sections (wheels and rings) bearing the rotor blades of the compressor. The sections are piloted together by overlapping interfitted flanges and are secured together by a polymer adhesive composition which is cured in place between the annular members and a containing ring spaced from them to define a cavity for the adhesive.

Claims Analysis
Total Claims: 4
Claim 1
Independent Claim
115 words
A turbomachine rotor of the axial flow type comprising a plural number of annular members fixed together in coaxial alignment defining a blade-supporting drum adapted for rotation about the axis of the members characterized by connections between adjacent members comprising, in combination, a rearwardly directed rim on a first said member, a forwardly directed rim on a second said member next rearward to the first member, a pilot joint between the two rims effective to align the members coaxially, a containing ring piloted on the said rims spaced radially from the pilot joint and defining with the said rims an annular cavity, and an adhesive filling the said cavity and holding the rims against separation.
Claim 2
Dependent Claim
115 words
A turbomachine rotor of the axial flow type comprising a plural number of annular members fixed together in coaxial alignment defining a blade-supporting drum adapted for rotation about the axis of the members characterized by connections between adjacent members comprising, in combination, a rearwardly directed rim on a first said member, a forwardly directed rim on a second said member next rearward to the first member, a pilot joint between the two rims effective to align the members coaxially, a containing ring piloted on the said rims spaced radially from the pilot joint and defining with the said rims an annular cavity, and an adhesive filling the said cavity and holding the rims against separation.
Claim 3
Dependent Claim
116 words
A turbomachine rotor comprising, in combination, a first annular bladed member having an axially extending rim portion, a second annular bladed member having an axially extending rim portion abutting the first rim portion, a mechanical interfit between the said portions providing relative radial and axial location of the two members, a containing ring radially spaced from the said interfit and axially aligned with the said interfit radially supported by the said bladed members and defining with the said members an annular cavity, the rotor defining access holes for injection of a plastic adhesive into the said cavity, and a cured plastic adhesive filling the said chamber and holding the said members cemented together in abutting relationship.
