I have an other idea to reduce heat on the rear bearing. Since there is a gap between the platform of turbine and the inner platform of NGV, so hot gas can intrude into the rear bearing area. We can drill some holes on the inner flange of NGV to let cooler air around the CC to push the hot gas back its original path. The cooler air has higher pressure than the gas from the NGV. Any comments about the issue?
