摘要：
In order to develop turbine blade life usage monitoring and understand impact of typical operating conditions on creep life consumption of high pressure turbine blade, an integrated turbine blade life consumption analysis model was established based on engine performance simulation model and multi-field conjugate method. Through introducing the life consumption factor, quantitative impact of typical operating conditions, such as flight altitude, ambient temperature, flight Mach number and high pressure rotor speed, on turbine blade temperature, stress and creep life consumption was found. Results show that operating condition indeed has a significant impact on turbine blade creep life consumption, among which the high pressure rotor speed has the maximal impact that logarithmic life consumption factor increases about 0.4 with rotor speed raise 1%. © 2017, Editorial Department of Journal of Propulsion Technology.
