MIL-HDBK-244A
designed to withstand this dynamic response or suffer a reduction in the maneuvering
flight envelope during stores release to the extent that the aircraft
limit load factor is not exceeded.
(h) Items specified- Thelimitations listed in (a) to (h)
apply to iron bombs, canisters, pods, rockets, missiles, guided weapons,
towed stores, submunitions, containers, dispensed munitions and suspension
equipment.
5.1.2 Store-to-aircraftclearances and fit. One of the first
analyses to be made in determining the compatibilityof a store,with a
particular aircraft is that of ensuring that the store will ~hysically fit on “-
the aircraft without interferingwith ~ny part of the aircraft; other-stores,
or the ground. See AOP-11 (STANAG 3791 AA and AIR STD 20/21), AOP-12
(STANAG 3898 AA and AIR STD 20/21), and MIL-STD-1289 (STANAG 3899 AA and
AIR STD 20/21) for the appropriate data.
5.1.3 Electrical interface. Many of the latest aircraft weapon
release systems are extremely complex and designed to deliver a multitude of
different types of weapons. Some of these weapons can be carried singly on a.
parent rack or on multiple ejector racks attached to parent racks---Many of
these stores require electrical connections to the aircraft. When the stores
are carried singly, only one harness or adapter is needed to connect it to
the aircraft; however, when a multiple rack is used, a harness is needed
between the aircraft and rack, and a harness for each weapon to connect it to
the multiple rack, may also be required. In all cases, however, electrical
connectors are required from the aircraft to multiple racks and launchers.
Refer to 5.4 for details on aircraft stores management system design
guidelines.
5.1.3.1 Categories. Since the first issue of MIL-STD-1760, there
are five major categories of stores and aircraft, with several
sub-categories. The five major categories are:
(1) New stores on new aircraft.
(2) Old stores (developedbefore 1981) on new aircraft.
(3) New stores on old aircraft (developed before 1981).
(4) Old stores on old aircraft that were designed to work
together.
(5) Old stores on old aircraft that were not designed to
work together.
Each of the stores and aircraft that have started development since 1981 are
required to be compliant with the revision of MIL-STD-1760 that was in force
when their development started. The compliance with MIL-STD-1760 greatly
reduced the difficulty and expense of adapting the electrical interface of
any of the new stores to the new aircraft. There will be some cost and
