SCOPE This document establishes techniques for validating that an Aircraft Station Interface (ASI) complies with the interface requirements delineated in MIL-STD-1760 Revision E.
19、 1.1 Purpose The purpose of this document is to provide methods for validating that an aircrafts store electrical interface complies with the aircraft station interface (ASI) requirements of MIL-STD-1760. This document provides a modular, independent set of methods for each of the requirements in MI
20、L-STD-1760 that applies to aircraft requirements. For verification of aircraft designed to MIL-STD-1760A, AS4764 applies. For verification of aircraft designed to MIL-STD-1760B, AS47641 applies. For verification of aircraft designed to MIL-STD-1760C, AS47642A applies. 1.2 Application The methods her
21、ein apply to initial verification of an aircraft design to the requirements of MIL-STD-1760 and are expected to be conducted as part of aircraft design verification (as opposed to qualification test, quality conformance test, flight line test, etc.). The methods contained in this document are suffic
22、ient to cover the Class I interface. Aircraft with Class II ASIs will use the appropriate subset of these Class I methods. 1.3 Tailoring The methods contained herein are general methods for conducting ASI verification and, as such, do not provide detailed procedures for these methods. It is intended
23、 that detailed procedures for verification of a specific ASI will be covered by tailored test plans and procedures prepared specifically for that aircraft. These tailored test procedures would, for example, address those peculiar commands required to step through sufficient operations and states to
24、demonstrate compliance with the particular aircraft/store electrical interconnection system (AEIS) requirement under test. 1.4 Limitations The methods contained herein are based on MIL-STD-1760E. In addition, this document addresses testing compliance of an aircraft to MIL-STD-1760 based on the assu
25、mption that all tests are conducted at the aircrafts ASI connector and measurements of performance occur only at this ASI. 1.5 Identification System The test methods contained in this document are designated by an alphanumeric identification scheme. Each method is identified by a three alphabetical
26、character combination followed by a three-digit number. The meaning of the first three individual letters is: a. HBW: High Bandwidth Interface b. MUX: Digital Multiplex Data Interface c. LBW: Low Bandwidth Interface d. REL: Release Consent Interface e. INL: Interlock Interface f. ADR: Address Interf
27、ace g. GND: Structure Ground h. 28 V: 28 VDC Power Interface i. ACP: 115 V/200 VAC Power Interface SAE INTERNATIONAL AS47643 Page 5 of 190 j. HVP: 270 VDC Power Interface k. FOC: Fiber Optic Channel l. INT: Initialization m. CON: ASI Connector n. UMB: Umbilical Cable o. FCI: Fiber Channel Interface
28、The three numbers following the letter code is a sequentially assigned number such that numbers 101 through 199 are for ASI requirements and 201 through 299 are reserved for mission store interface (MSI) requirements. When applicable, the letter following this three-digit number is the test method r
29、evision letter. For example, HBW101 represents the original version of the first test requirement (TR) for the ASI HBW interface while HBW101A represents the first revision of that requirement. 2.

40、L-STD-1760. 2.3.2 UNIT UNDER TEST (UUT) The UUT is defined as the “production configuration aircraft” undergoing verification tests. The test point for all electrical tests is the ASI. 2.3.3 VERIFICATION Verification is defined as the process whereby the final design of an AEIS is evaluated to deter
41、mine its compliance with the requirements imposed by MIL-STD-1760. This compliance evaluation is accomplished using a combination of techniques including tests, analysis, and inspections. This verification is conducted to determine that the design complies with MIL-STD-1760 under nominal ambient con
42、ditions. While this verification may be part of an aircrafts qualification test (if specified in the aircrafts system specification), it is not necessarily intended to be conducted under all aircraft environmental and operational conditions and, as such, does not specifically “qualify” the aircraft
43、to its system specification/interface control document (ICD) requirements. The addition of a new column, titled “Shall Statement”, in each of the fourteen (14) Verification Tables, clearly identifies the requirement to be validated. The numbers in the column are directly linked to the corresponding
44、“shall” statement in the order that it appears in the MIL-STD-1760 paragraph. For example, In Table 6 Address Verification Matrix, MIL-STD-1760 paragraph 5.1.6, the first two (2) shall statements, as they appear on 1760, are validated using test method ADR101 while the third (3) shall statement is v
45、alidated using test method ADR102. In this way, the requirement is easily identified, traceable to MIL-STD-1760 and therefore must be followed or adhered to (tested) to verify overall system compliance to MIL-STD-1760. 3. GENERAL REQUIREMENTS 3.1 Introduction As part of an aircrafts qualification to
46、 its system specification requirements, the AEIS design shall be validated against the requirements of MIL-STD-1760. The specific verification effort for a given ASI will be defined in a test plan prepared for the AEIS. The methods defined in this document provide guidance for the preparation of the
47、 test plans by delineating the pertinent requirements in MIL-STD-1760 and verification methodology. For those requirements that can be validated by test or analysis, this document also provides test techniques. Section 4, herein, presents verification details associated with each requirement in MIL-
48、STD-1760. 3.2 Verification Techniques Verification of a design to the requirements of MIL-STD-1760 can be accomplished through the use of a number of techniques. A general listing of these techniques includes: a. Test b. Analysis c. Inspection 3.2.1 Test Tests are those methodologies that measure ch
49、aracteristics or performance under specified conditions. Tests also include techniques that “demonstrate” operation of circuitry or system performance. SAE INTERNATIONAL AS47643 Page 9 of 190 3.2.2 Analysis Analyses are those methodologies that verify design compliance with the designated requirements of MIL-STD-1760 without performance of verification test or inspection. These methodologies will primarily be based on technical evalu
