Abstract
Abstract A mounting system for a gas turbine power unit in which the stator housing is supported by an annular mounting ring having a radial spline connection to the stator housing, the mounting ring and turbine rotor being supported from a common base structure whereby the rotor and stator housing remain coaxial notwithstanding thermal expansions and contractions of the stator housing and/or rotor.

Claims Analysis
Total Claims: 3
Claim 1
Independent Claim
43 words
A mounting system as claimed in claim 1 and including a pair of springs disposed on opposite sides of the power unit axis and adjacent to the downstream end of the exhaust duct for resiliently supporting said exhaust duct from said base structure.
Claim 2
Dependent Claim
90 words
A mounting system as claimed in claim 2 and in which when the power unit is cold the upper end of each spring connected to the exhaust duct is displaced both in an upstream direction relative to its lower end connected to the common base structure and is also displaced inwardly toward the axis of the power unit relative to its said lower end so that as a result of thermal expansion of the exhaust duct the axis of each spring becomes substantially vertical when the power unit is operating.
Claim 3
Dependent Claim
60 words
A mounting system as claimed in claim 1 in which said mounting ring and its flange have a split construction and include a one-piece ring secured to said flange and on which said inwardly facing splines are formed and further in which said stator vane assembly also has a split construction but said annular mounting flange is a one-piece member.
