Patent ID: 7277838

Claim:
A method for modeling engine operation comprising the steps of: 1. inputting a first plurality of sensory data from a gas turbine engine into a computer; 2. partitioning a flight envelope into a plurality of sub-regions according to the steps of: 3. selecting a first sensory parameter and a second sensory parameter, 4. plotting each of said first plurality of sensory data by using said first sensory parameter as a first axis and said second sensory parameter as a second axis, and 5. dividing said first axis and said second axis into a plurality of subdivisions to create a grid comprising a plurality of sub-regions; 6. assigning said first plurality of sensory data into said plurality of sub-regions; 7. generating an empirical model of at least one of said plurality of sub-regions; 8. generating a statistical summary model for at least one of said plurality of sub-regions; 9. inputting an additional plurality of sensory data from said gas turbine engine into said computer; 10. partitioning said second plurality of sensory data into said plurality of sub-regions; 11. generating a plurality of pseudo-data using said empirical model; 12. concatenating said plurality of pseudo-data and said additional plurality of sensory data; and 13. outputting using said computer an updated empirical model and an updated statistical summary model for at least one of said plurality of sub-regions.
