STATOR OF HIGH PRESSURE COMPRESSOR

PROBLEM TO BE SOLVED: To provide a stator suitable for the high pressure compressor of a gas turbine engine which can dissolve the problem caused by an ununiform ventilation. SOLUTION: A stator is provided with two ventilations 17, 18 with a different temperature. The upstream side section of the st...

Zusammenfassung:	PROBLEM TO BE SOLVED: To provide a stator suitable for the high pressure compressor of a gas turbine engine which can dissolve the problem caused by an ununiform ventilation. SOLUTION: A stator is provided with two ventilations 17, 18 with a different temperature. The upstream side section of the stator is constituted by a casing 10 and shroud 11, and it is recommended that these both have no notch over an entire periphery and are formed by a material with a low thermal expansion rate. But, at the downstream side, the shroud users plural arc shape sectors consisting of a material with high thermal expansion rate.
