Some Issues Relating to Design and Development of an All-Composite Aero Gas Turbine Engine Rotor

  • K. Gupta Indian Institute of Technology Delhi, New Delhi
Keywords: Composite aero gas, Turbine engine rotor


The paper addresses some of the issues involved in the development of an all-composite aero gasturbine engine rotor with a view to reducing the total engine weight and increasing the thrust-weightratio beyond 20: I. It identifies the materials to be used for different components, i.e. shafts, discs andblades in the high and iow temperature regions. The various problems anticipated in its developmentare discussed and solutions recommended, wherever possible.
