Title:
METHOD OF IMPROVING PERFORMANCE OF GAS TURBINE ENGINE
Document Type and Number:
Japanese Patent JP2015163793
Kind Code:
A
Abstract:
PROBLEM TO BE SOLVED: To provide a method of improving performance of a gas turbine engine.SOLUTION: A method of improving performance of a gas turbine engine particularly comprises: determining fan tip speed boundary conditions for at least one fan blade of a fan section; determining rotor boundary conditions for a rotor of a low pressure turbine; and utilizing stress level constraints in the rotor of the low pressure turbine and the at least one fan blade to determine if the rotary speed of the fan section and the low pressure turbine meets a desired number of operating cycles.
