2、le Forms: N/A Use/relationship: This Data Item Description (DID) provides the method for presentation of gas turbine engine steadystate and transient performance calculated using digital computer programs. It also provides for the presentation of parametric gas turbine data including performance, we
3、ight and dimensions computed by digital computer programs. The information is intended to facilitate calculations by the program user without unduly restricting the method of calculation used by the program supplier. a. This DID contains the format, content and intended use of information for the da
4、ta resulting from the work task described in the Society of Automotive Engineers (SAE) Aerospace Standard 681 and SAE Aerospace Standard 755. b. DITMSS81515B supersedes DITMSS81515A. Requirements: 1. Reference Documents. The applicable issue of the documents cited herein, including their approval da
5、tes and dates of any applicable amendments, notices, and revisions, shall be as cited in the contract. 2. Format. Contractor format is acceptable. 3. Content. The Users Manual shall contain the information required by SAE Aerospace Standard 681. In addition, the Users Manual shall contain the follow
6、ing: 3.1. A detailed explanation of the performance calculation process for each engine component, including an index of all subroutines in the model including explanations of their purpose, and identification of the function of each programming variable and array element, detailed explanations of t
7、he derivations of all empirical functions used in the model, and the rationale for all reference values used for normalized parameters. 3.2. An identification of any limits on the values of input parameters. 3.3. Accurate graphic component performance maps of the fans, compressors, turbines, and exh
8、aust nozzles simulated in the model. 3.4. A detailed description of the major engine control loops, the hierarchy of the loops, the control limits, and graphs of all engine control schedules represented in the model. 4. End of DITMSS81515B.
