In this chapter we will discuss the system aspects of weapons integration. The chapter is not concerned with loads, flutter, captive carry, or station clearance issues, although they will be touched upon during the discussions. As usual, some references are available to the evaluator, and these will be quoted where necessary. The first reference is the MIL-STD-1760D, “Interface Standard for Aircraft-Store Electrical Interconnection System,”August 1, 2003. This document covers the digital data bus requirements for aircraft and stores, and was covered at some length in chapter 3 of this text. The second is MIL-HDBK-1763, “Aircraft/Stores Compatibility: Systems Engineering Data Requirements and Test Procedures,”June 15, 1988. A detailed examination of the requirements in 1763 is covered in section 10.5. A third reference is from the NATO Aerospace Group for Avionics Research and Development (AGARD), now called the NATO Research and Technology Organization. AGARD Flight Test Techniques Series, Volume 10, “Weapon Delivery Analysis and Ballistic Flight Testing,”July 1992, is perhaps one of the better documents available to evaluators for the test and evaluation of weapons systems. The highlights of this AGARD document are explained in section 10.6. A general document used for all aircraft is Mil-A-8860B, “General Specifications for Airplane Strength and Rigidity,”May 20, 1987.
