Abstract: An example gas turbine engine compressor includes a first compressor section. The first compressor section includes rotating stage that includes rotating blades and a stationary stage upstream thereof that includes stationary guide vanes. The stationary vanes controllably pivot about respective pivot axises for providing flow control into the rotating stage.
