DATA ITEM DESCRIPTION
Title: User’s Manual for Gas Turbine Engine Steady-State and Transient Performance
Presentation for Digital Computer Programs
Number: DI-TMSS-81515C Approval Date: 20150519
AMSC Number: F9546 Limitation: No
DTIC Applicable: No GIDEP Applicable: No
Preparing Activity: 11 Project Number: TMSS-2015-005
Applicable Forms: N/A
Use/relationship: This Data Item Description (DID) provides the method for presentation of
gas turbine engine calculated steady-state and transient performance using computer programs.
It also provides for the presentation of parametric gas turbine data including performance,
weight 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 data
resulting from the work task described in the Society of Automotive Engineers (SAE)
Aerospace Standard 681 and SAE Aerospace Standard 755 (SAE documents can be
obtained at http://www.sae.org/).
b. This DID is related to DI-MSSM-81966, “Gas Turbine Engine Steady State and
Transient Performance Presentations for Computer Programs” (DI-MSSM-81966 can
be obtained at http://quicksearch.dla.mil).
c. DI-TMSS-81515C supersedes DI-TMSS-81515B and DI-IPSC-81490.
Requirements:
1. Reference Documents. The applicable issue of the documents cited herein, including their
approval dates and dates of any applicable amendments, notices, and revisions, shall be as
specified in the contract.
2. Format. Contractor format is acceptable.
3. Content. The User’s Manual shall contain the information required by SAE Aerospace
Standard 681. In addition, the User’s Manual shall contain the following:
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 the 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 exhaust 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.
