This section will include program variable names, station identification, and other information required to understand the

23、Users Manual.6. Program Set-Up. This section will include instructions and information to enable the program users computer staff to set up the program.7. Program Capabilities. This section will describe the interfaces, logic options, limits, and other program features that enable the user to unders

24、tand fully the capability of the program.8. Input/Output. This section will describe in detail the input required to use the features described in Item 7 of this section, the output the program produces, and will list the units of all input and output parameters.9.

References.3.5 Program Scope:3.5.1 Categories of Programs to be Considered: Engine test data reduction p

28、rograms may range from programs that are limited to calculation of external performance, e.g., thrust, fuel flow, and airflow, to those that include an analysis of component performance for consistency checks.3.5.2 Limits: All known limits will be defined in the Users Manual, e.g., range of input pr

29、essure and temperature limits for which calibration curves are supplied, range of component performance which is supplied, or range of thermodynamic data for which calculations are valid. When the input data calls for an operating point outside limits, the program will proceed to complete its calcul

30、ation, if possible, and output the appropriate status indicator. The status indicators will clearly define the validity of the data. The program will always be capable of continuing with the next case provided the users subroutines and/or computer operating system do not override this capability.SAE

32、ations to determine the accuracy of significant output parameters.4. PROGRAMMING PRACTICES:4.1 Equipment Capabilities:The users measurement system and computer capabilities may limit the program. Program development must be preceded by user/supplier coordination.4.2 Program Language:Any computer lan

33、guage (e.g., C, ADA, FORTRAN 77) may be used for engine computer programs if the language has been coordinated between the user and the supplier. If not otherwise coordinated, engine computer programs will use as a minimum language FORTRAN 66 level: full FORTRAN (Number 1) as originally defined in A

34、NSI X3.9, 1966a. This language may be augmented by features found in the commonly used FORTRAN languages of industry when these features are known to be acceptable to the program users. ARP4191 contains additional information for FORTRAN 77 applications.4.3 Station Identification and Nomenclature:St

35、ation identification and nomenclature will be consistent with AS755. Supplements to the system of AS755 that are necessary will be detailed in the Users Manual.Nomenclature symbols are not required to be used for variable names within the program. While the use of the same nomenclature within the pr

36、ogram may have merit in certain instances, such use will unduly restrict the program supplier and thus will be left to the discretion of the program supplier or to coordination between program user and supplier.4.4 Standard Atmosphere:Ambient temperature and pressure will be consistent with the geop

37、otential pressure altitude of ISO 2533.4.5 Program Thermodynamics:4.5.1 Standard Dry Air: The composition of standard dry air is to be based on that used for ISO 2533, but with the number of molecular species reduced by the reallocation of trace elements. The composition will be defined in the Users

38、 Manual upon request by the customer.4.5.2 Fuel: Fuel heating value assumed by the computer program will be specified in the Users Manual. Fuel specific gravity will also be specified if it is used in the performance calculation or its associated control model. Other fuel characteristics used in the

39、 program will be provided in an appendix to the Users Manual, upon request by the customer.SAE INTERNATIONAL ARP1210D Page 6 of 11_ Copyright SAE International Provided by IHS under license with SAENot for ResaleNo reproduction or networking permitted without license from IHS-,-,-4.5.3 Thermochemica

40、l Data: Thermochemical data used in the computer program will be defined in the Users Manual upon request by the customer. Thermochemical data for the purpose of gas turbine engine performance calculations will be consistent with data presented in the NIST-JANAF Thermochemical Tables, Fourth Edition

41、, Parts I and II, within the limitations of physical representation (e.g., reaction rates, heat transfer), engineering accuracy, and computational efficiency requirements. Upon request by the customer, the supplier will supply a comparison of the thermodynamic process calculations based on his/her t

42、hermochemical data and that given by the NIST-JANAF Thermochemical Tables within the range of applicable engine operating conditions.4.6 Programming Standards:The level of compiler optimization requires coordination between user and supplier.The program supplier will provide automatic preventive act

43、ion for the following illegal arithmetic operations or processes: the square root of a negative number, illegal arguments to exponential, logarithmic and inverse trigonometric subroutines. The numerical status indicator will clearly define the validity of the output. The program will always be capab

44、le of continuing with the next case provided the users subroutines and/or computer operating system do not override this capability.5. PROGRAM CAPABILITIES:5.1 Installed Performance Effects:The program will be capable of processing applicable installed performance and variable geometry position data

45、.5.2 Program Logic:Where practical, the program will supply the logic for a course of action:a. When a data element is missingb. When the data element is present but is rejected based on instrumentation evaluationc. When bad data are recognized through program consistency checksd. When bad data are

46、recognized to be present on the basis of the test historyThese items may require special input signals to the program. The program will indicate which logic paths have been rejected, which input data values have been rejected, and what alternate assumptions have been made to complete the analysis.6. INPUT/OUTPUT:6.1 Program Interface Definition:The communication between the calling program (written by either the program supplier or user) and the remainder of the reduction program will be coordinated individually between user and supplier.SAE INTERNATIONAL ARP1210D Page 7 of 11_
