Abstract
A removable disk for an annular casing in a turbomachine is disclosed. The disk is coaxial with the casing and slideably engagable with the casing in ambient conditions. The disk radially contacts the casing during operation so as to provide increased stiffness to the casing.
Claims8
A removable stiffening member for an annular casing in a turbomachine comprising a substantially rigid disk coaxial and slideably engagable with said casing at ambient conditions, wherein said disk radially contacts said casing during turbomachine operation generally continuously along an entire circumferential surface of said casing so as to provide circumferential and axial restraint of said disk and increased stiffness to said casing.
A removable stiffening member for an annular casing in a turbomachine, comprising:
- a substantially rigid annular disk adapted to contact said casing during turbomachine operation at a multiplicity of diametrically opposed locations so as to provide circumferential and axial restraint of said disk and to provide radial support and stiffness to said casing;
- a bracket for axially positioning said disk;
- first fastening means for removably attaching said bracket to said disk;
- and
- second fastening means for removably attaching said bracket to said casing.
A removable, substantially rigid disk adapted to contact an annular casing in a turbomachine, wherein said disk radially contacts said casing generally continuously along the entire inner circumferential surface of said casing so as to provide increased stiffness to said casing.
A turbomachine including:
- an annular casing, said casing having a natural resonant frequency of vibration;
- and
- a substantially rigid stiffening member adapted to contact said casing during turbomachine operation at a multiplicity of diametrically opposed locations, wherein said stiffening member is effective for raising said resonant frequency so as to avoid resonant frequency vibration of said casing during turbomachine operation.
