Case Study 1
Case in Point #1: A Fortune 100 Aerospace Company Achieves Significant
Cost Savings
Designers at a major aerospace company wanted to try to reduce the weight of a
turbine disk design. The Low Cycle Fatigue (LCF) at various disk locations was
calculated as a function of variations in temperature, rotor speed, pressure,
material properties, blade loads, snap fits and dimensions.
How PredictionProbe Solutions Helped
Probabilistic Analysis showed that, although standard engineering design
practices were used, the design was heavier than necessary. The design could
be reduced by around 8% and still exceed requirements.
Result
Approximately 8 lbs. of weight were removed from the 100-lb. disk. Over the
life cycle of a fleet of engines, the cost savings in raw material and
performance was $90 Million.
