Piccolo tube anti icing system
Webb1 sep. 2024 · The “piccolo-tube” is taken from the concept of hot-bleed-air pattern in the jet impingement anti-icing configurations of aircraft [ 37, 38 ]. The air bleed tube looks like a piccolo where a row of holes are located on a tube wall. This piccolo-tube is located with a normal distance ( h) of 0.06 m from the bottom wall of mixing chamber. WebbAn anti-icing system is provided with a pair of piccolo tubes, each tube being housed within a respective one of the slats and having spray holes for delivering hot gas to a leading edge...
