An improved rotary labyrinth seal such as may be used in a gas turbine engine. The seal includes a rotor with at least one seal tooth and a stator with an abradable shroud and casing. The first and second members cooperate to inhibit the flow of fluid therebetween. The improvement comprises a conduit for conducting a portion of the fluid through the casing for heat transfer between the fluid and second member. In this manner, the thermal response of the stator is improved. |
