Abstract
The air inlet (10) which has a particle separator to prevent turbine blade damage, has an outer fairing (14) and an inner fairing (16) which together with an inner casing (16) form an annular channel. The channel has a first section (EP) guiding the intake air in an axial direction towards the compressor. The second section curves inwards radially to enter the compressor in a radial direction. A number of hollow impeller shaped struts (20) are arranged at an angle and a proportional distance from one another between the curved inner casing (18) and the outer fairing. A 'V' shaped snare (22) catches material particles from the inner part of the air flow and drops them into the pocket section (24). The particles in the outer air flow are caught and transferred into upper pocket sections (26). The two pocket sections are concentrica to the turbine axis and over adjoining tension struts, which open into a main an (32) inside the interior casing (18) and provided with an outlet (34) aerodynamically coupled to an extractor fan (B).
