COMPRESSED-AIR SYSTEM AND COMPRESSED-AIR UNIT

摘要

PROBLEM TO BE SOLVED: To provide a de-icing and surge control device capable of controlling surge by efficiently and rapidly de-icing an inlet in a compressor of an airplane. SOLUTION: A housing 40 comprises a diffuser shroud 68 and a heating plenum 72 formed by a heating housing part 46. The diffuser shroud 68 provides a curved annular wall 70 gradually widening to the radial outer side as it axially extends from the end of an impeller. A relatively short duct 30 connects an outlet 22 to the inlet of the heating plenum to flow a fluid therein. Consequently, the de-icing and surge control can be quickly performed.
