b.
Operating forces, release mechanism test; horizontal release check, dive and c1imb, HBB items
check.
Manual releases of a Type II bomb rack shall be accomplished by pulling the manual release
cable assembly. Release forces and travel distances shall be measured when pulling the manual release
cable assembly in the vertically upward direction. A minimum of three measurements shall be performed.
The release forces shall be recorded. The travel distance necessary to effect release shall be no greater than
15/ 16 inch (2.38 centimeters).
Electrical characteristics. This test shall be conducted with the following exceptions:
4.6.7.2
The class of insulation shall be considered class A fix temperature rise tests of the electro-
a.
magnetic units.
b.
The test temperature shall be 93.3C (200 F) when conducting the insulation resistance test.
c.
The minimum operating voltage shall be determined by demonstrating that all electrical
equipment on the bomb rack operates when 20 VDC is applied to the terminals of the
applicable bomb rack connectors.
4.6.7.3
Lag determination. This test shall be conducted in accordance with the lag or time of
release determination test for horizontal bombing (HB) items, except that the mean deviation requirement
for lag times shall not apply. When testing a Type I bomb rack, the IFOBRL shall be operated using 20
VDC sustained whenever a 20 VDC, 20-millisecond pulse is required to effect a store release. A 101 pound
(45.81 kilogram) store shall be used for lightest store releases and a 2,200 pound (997.90 kilogram) store
shall be used for heaviest store releases.
High-g release. This test shall be conducted, except that the total vertical down load
4.6.7.4
shall be 7,975 pounds (3,617.46 kilograms). When testing a Type I bomb rack, the secondary release
assembly shall be replaced after each use.
4.6.7.5
Sand test. This test shall be conducted in accordance with the dry sand and room
temperature portions of the sand test with the following exceptions:
a.
Type I and Type 11 bomb racks.
1.
The force required to arm test shall not apply.
The arming wire pulls, safe setting, shall not apply.
2.
b.
Type I bomb racks only.
1.
The IFOBRL shall be locked prior to the dry sand exposure period.
2.
The IFOBRL shall be operated using 20 VDC sustained whenever a 20 VDC, 20
millisecond pulse is required to effect a store release.
