scope:

Use/Relationship: Engine steady state and transient computer programs (herein referred to as Models) provide a detailed description of the aerothermodynamic cycle performance and stability characteristics of the Propulsion System. These Models will be provided to the Using Service for evaluation of Propulsion System performance and stability characteristics during source selections, evaluations/studies during the development program, and post-qualification modification evaluations throughout the life of the program.

This Data Item Description contains the format and content preparation instructions for data resulting from the work task described by 3.2.1 and 4.2.1 of Aircraft Turbine Engines Joint Service Specification Guide 2007 (JSSG-2007).
