Design of an Improved Turbine Rim-Seal [PDF]
Volume 5C: Heat Transfer, 2015 Rim seals are fitted in gas turbines at the periphery of the wheel-space formed between rotor discs and their adjacent casings. These seals, also called platform overlap seals, reduce the ingress of hot gases which can limit the life of highly-stressed components in the engine.
