TY - JOUR AU - K. Gupta PY - 2013/01/01 Y2 - 2024/03/28 TI - Some Issues Relating to Design and Development of an All-Composite Aero Gas Turbine Engine Rotor JF - Defence Science Journal JA - DSJ VL - 48 IS - 1 SE - Armaments & Explosives DO - 10.14429/dsj.48.3871 UR - https://publications.drdo.gov.in/ojs/index.php/dsj/article/view/3871 AB - 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. ER -
