Abstract: An actuator for adjustable stator vanes in a gas turbine engine. A torque tube is rotatable about its axis, and supports devises which connect to links. The links are connected to rings, and rotate the rings when the torque tube rotates, thereby adjusting stator vanes connected to the rings. A linear actuator, having a motion axis parallel to the torque tube, drives the torque tube, through a linear-rotary convertor. The invention occupies less space on the engine, and requires no adjustment of the linear-rotary convertor after installation.

Abstract: An infrared suppressor system for a gas turbine engine is provided for suppressing infrared radiation associated with the hot metal parts of the engine and with the hot exhaust gases exhausted from the engine. The system features a unique arrangement of multiple baffles that are connected together as a single baffle module. The baffle arrangement permits mixing of hot and cool gas flows while eliminating line-of-sight infrared radiation in an axially compact suppressor. The baffles are additionally linked together into a single insertable baffle module that permits removal of the baffle module when infrared suppression is unnecessary.
