Ēriks Ozoliņš, Ilmārs Ozoliņš, Līga Ramāna

Abstract


The article describes the impact of the gas turbine engine low-pressure turbine blade shroud shelf on the blade profile stress position. Attention is focused directly on the impact of the location of the gravity centre of the shroud shelf on blade stress distribution at the three most critical points of the profile. The paper describes the details of the calculation and the required expressions provided, as well as the results of the calculation example with clear graphical dependencies.

Keywords:
Turbine blade; shroud shelf; blade load removing
