Abstract: A variable vane mechanism for adjusting the angle of stator vanes in a gas turbine engine is provided. The mechanism has a circumferentially extending drive ring that is driven by an actuator, and a guide surface that is radially inside the drive ring. The mechanism also has a centralising pin that is connected to the drive ring and also in slidable contact with the guide surface so as to be movable with the drive ring relative to the guide surface. The centralising pin allows both the drive ring to be connected to a stator vane (via a lever) in order to adjust the angle of the vane, and the radial position of the drive ring to be adjusted to ensure accurate and repeatable operation of the mechanism.

Abstract: A combustor assembly for a gas turbine engine includes a combustor shell extending along a shell axis. The combustor shell includes a shell wall extending around the shell axis and a meter panel connected to an upstream end of the shell wall. The shell wall and the meter panel together define a combustion space therebetween. The combustor assembly further includes: a tile disposed within the combustor shell and including a tile flange portion extending radially with respect to the shell axis; a heatshield connected to the meter panel and extending at least radially towards the tile; a fastener connecting the tile flange portion to the meter panel; and a compartment thermally shielded from the combustion space. Either the heatshield and the tile together form the compartment or the tile alone forms the compartment. The fastener is spaced apart from the combustion space and at least partially disposed within the compartment.
