摘要： An air bleed system for a gas turbine engine includes an annular bleed case with a manifold therein. The annular bleed case has a forward section and an aft section and ligaments connecting the two sections. The forward section, the aft section and the ligaments define bleed ports. The manifold is disposed radially outward of the ligaments and communicates with the series of bleed ports.

摘要： Bleed valve assemblies in a gas turbine engine are disclosed herein. A bleed valve assembly in a low pressure compressor may include a bleed valve and a resonator chamber. A manifold may allow passage of air from a bleed duct into the resonator chamber. The resonator chamber may alter resonation properties of the bleed duct in order to prevent damage to components in the low pressure compressor.

摘要： An example vane arm testing rig includes a base having a first attachment configured to receive a first end of a vane arm when the vane arm is in an engaged position, and a torque member having a second attachment configured to receive an opposing, second end of the vane arm when the vane arm is in the engaged position. The vane arm extends along a longitudinal axis from the first end to the second end. The first and second attachments are configured to rotate relative to each other about the axis. The first and second attachments are configured to move laterally relative to each other.
