Performance Retention Features of the PW2037 811054
The PW2037 (formerly called JT10D) incorporates design and maintenance features for performance retention, many of which evolved from recommendations developed in studies funded by the National Aeronautics and Space Administration. A maintenance concept called on-condition/threshold refurbishment is recommended for the PW2037 for improving performance retention. The PW2037 is estimated to have performance deterioration less than two percent in fleet average cruise specific fuel consumption in 32,000 flight cycles when maintained according to recommendations.
