Tracking microscopic turbine blade hot-section degradation to extend on-wing engine life safely.
Ingesting airborne pollutants and dust erodes high-pressure compressor blades, reducing adiabatic efficiency. By comparing measured pressure and temperature ratios across engine stations, the digital twin separates aerodynamic fouling from physical tip clearance wear.
As engines age, EGT rises to produce identical takeoff thrust. The digital twin predicts when the EGT margin will reach zero, scheduling water washes and derated takeoff thrust settings to keep engines flying safely for additional months.
