<p>A gas turbine casing for enclosing a gas turbine component, such as a fan, a compressor, a combustion chamber or a turbine. The casing comprises a double wall structure (14) having a first inner tube (15) and a second outer tube (16), the first inner tube (15) and the second outer tube (16) extending around a geometric longitudinal axis (17), which is intended to basically coincide with a longitudinal geometric central axis of a gas turbine. The first inner tube (15) and the second outer tube (16) overlap one another when these are viewed in a radial direction, a gap (18) being formed between the outer boundary surface (19) of the first inner tube and the inner boundary surface (20) of the second outer tube. The double wall structure (14) furthermore has a plurality of stays (21) which take the form of plates, which are spaced at an interval from one another and extend radially between the first inner tube (15) and the second outer tube (16), and which stays (21) connect the first inner tube (15) and the second outer tube (16) to one another.</p> |
