Partikelfalle für Turbomaschinen

摘要

The particle trap (15), forming part of a turbine intake housing mounted on a surrounding structure by means of suspension members (10), consists of an annular chamber open at the front to the incoming air flow. The trap is bounded at the rear by a circular flange (12) with connecting lugs (13) for the suspension arms. The chamber is divided by suspension arms (11) which extend forwards and towards a rotor shaft (2) from the flange opposite the suspension member connecting lugs as far as a reduction gear housing (1) containing the rotor. The trap is bounded on the outside by a cover with ports located just above the suspension arms.
