The spreading of a so-called titanium fire is prevented in a turbine engine in which at least one turbocomponent, e.g. the compressor, including its stator inner and outer housing sections and the rotor are made substantially or completely of titanium or of a titanium alloy, by a heat-dissipating layer on an outer housing section surrounding an inner housing section directly facing the rotor. A radial spacing is provided between the inner and outer stator housing sections. The heat-dissipating layer of a highly heat-conducting material covers the inner surface of the outer stator section and permits the concentrated thermal energy of, e.g., a glowing titanium particle, after is has burned through the stationary inner stator section or wall, to be dissipated fast enough to prevent an ignition of the outer stator section to thereby restrict the damage to the inner stator section.

An apparatus for preventing the spreading of titanium fires in gas turbine engines having a rotational axis, comprising stator means (7, 8, 9, 10, 11) and rotor means (17, 18, 19, 20, 21, 22) operatively supported in said stator means, said stator means and said rotor means being made, at least partially, of titanium or of a titanium alloy, wherein said stator means comprise a first inner stator section (A) located radially adjacent to and around said rotor means for forming a gap between said rotor means and said first inner stator section (A), and a second outer stator section (B) operatively surrounding said first inner stator section (A) with a radial spacing (5) between said first (A) and second (B) stator sections, said second outer stator section (B) comprising a radiallly inwardly facing surface and a layer (S) of highly heat-conducting material intimately bonded directly to said inwardly facing surface, said heat-conducting layer preventing said spreading of titanium fires.
