Gas turbine engine with lifing calculations based upon actual usage

A system comprising:

• a ground-based evaluation system programmed to perform the following steps:
• (a) receiving information from actual flights of an aircraft including an engine to be monitored, and including at least one of the ambient temperature at takeoff, and internal engine pressures, temperatures and speeds;
• (b) evaluating the damage accumulated on an engine component given the data received in step (a);
• (c) storing the determined damage from step (b);
• (d) repeating steps (a)-(c);
• (e) recommending a suggested future use for the component based upon steps (a)-(d);
• wherein the storing of step (c) is supplemented to provide information on missing flight information.

A method of monitoring a gas turbine engine comprising the steps of:

• (a) receiving information from actual flights of an aircraft including an engine to be monitored, and including at least one of the ambient temperature at takeoff, and internal engine pressures, temperatures and speeds;
• (b) evaluating the damage accumulated on an engine component given the data received in step (a);
• (c) storing the determined damage from step (b);
• (d) repeating steps (a)-(c);
• (e) recommending a suggested future use for the component based upon steps (a)-(d);
• wherein the recommended future use includes a suggestion to utilize a particular component or engine on a particular type flight.
