Abstract
A booster compressor includes inlet guide vanes supported from a shroud. A shell surrounds the shroud and defines a manifold. A splitter nose includes a groove receiving a forward tang of the shroud with a clearance therebetween defining an outlet for the manifold. Hot air is channeled through the manifold and out the splitter nose for deicing thereof.
Claims29
A booster compressor comprising:
- a row of solid inlet guide vanes supported from an annular shroud, and followed by alternating stages of rotor blades and stator vanes;
- an annular shell surrounding said shroud and defining a manifold;
- a splitter nose including an aft facing groove, and said shroud includes a forward tang disposed in said groove with a clearance therebetween defining an outlet for said manifold;
- and
- means for channeling hot air into said manifold for deicing said splitter nose.

A booster compressor comprising:
- an annular shroud including a forward tang at a forward end, and an aft flange at an opposite aft end;
- a row of inlet guide vanes supported from said shroud, and followed by alternating stages of rotor blades and stator vanes;
- an external splitter shell surrounding said shroud to define a manifold, and having a splitter nose at a forward end and an aft flange at an opposite aft end sealingly joined to said shroud aft flange;
- said splitter nose including an aft facing groove receiving said shroud forward tang with a clearance therebetween defining an outlet for said manifold;
- and
- means including an inlet disposed in said shell aft flange for channeling hot air into said manifold for forward flow over said shroud.
3 more elements
A booster compressor comprising:
- an annular shroud including a forward tang at a forward end, and aft flange at an opposite aft end;
- an internal shell surrounding said shroud to define a manifold therebetween, and said shell includes a forward end concentrically surrounding said shroud to define an internal outlet therebetween, and an aft flange at an opposite aft end thereof sealingly joined to said shroud aft flange;
- a splitter nose including an aft facing groove, and said shroud forward tang is disposed in said groove with a clearance therebetween defining an outlet for said manifold;
- a splitter skin fixedly joined to an aft end of said splitter nose, and surrounding said internal shell;
- and
- means including an inlet in said aft flange of said shell for channeling hot air into said manifold for deicing said splitter nose.
