MOUNTING FOR VARIABLY SETTABLE STATOR BLADES IN A COMPRESSOR

摘要

Each blade of a stage of variably settable stator blades in a compressor of a gas turbine engine is supported at its outer end by a journal which is rotatably mounted in a radial bore in a parallelepipedic journal box of trapezoidal section mounted in a housing of complementary shape formed between connected upstream and downstream rings of the outer casing of the compressor. The blade is held radially in the journal box by two parallel pins arranged longitudinally through the box so as to engage in a peripheral groove extending at least partly around the journal of the blade.
