Abstract: 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.

Abstract: A variable vane assembly for use in a gas turbine engine includes a variable vane, an actuator, and a mechanical linkage. The mechanical linkage connects the variable vane to the actuator. The mechanical linkage includes a bellcrank rotatable about an axis, a first bellcrank arm having a first clevis at an inner end, and a first pin extending through the first clevis and a first flange of the bellcrank to fasten the first bellcrank arm to the bellcrank.
Abstract translation: 用于燃气涡轮发动机的可变叶片组件包括可变叶片，致动器和机械联动装置。 机械联动将可变叶片连接到执行机构。 机械联动装置包括可围绕轴线旋转的曲拐，在内端具有第一U形夹的第一曲拐臂和延伸穿过第一U形夹的第一销和曲拐的第一凸缘，以将第一曲拐臂紧固到曲拐。
