VARIABLE DIAMETER PICCOLO TUBE FOR ANTI-ICING SYSTEM

A piccolo tube (152) for an anti-icing system may comprise an annular tube (156) and a plurality of openings (154) formed along a circumference of the annular tube. The annular tube may comprise a first cross-sectional diameter (D1) at an inlet point (160) and a second cross-sectional diameter (D2) at a distal point (162). The second cross-sectional diameter is less than first cross-sectional diameter. The distal point may be 180° from the inlet point.
