ABSTRACT:
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.
