Abstract
A thermal seal and insulating assembly for the low pressure turbine stage of a gas turbine engine having an inner liner and an outer liner which are connected by a 360.degree. ring. The ring serves to insulate a low pressure turbine case which is located radially outward from the outer liner from high temperature fluid flow. The inner liner is integrally connected to a liner extension located at the front of the inner liner. The liner extension deflects thermal fluid flow away from the inner liner. The inner liner and outer liner house a plurality of tubular and axially aligned honeycombed cells which provide a barrier against radiation heat transfer.
