a.
Conducted and radiated emission levels emitted by the bomb rack shall not exceed those
values depicted in Figures 1 through 3.
The power line configuration during conducted emission testing shall include a 7 microhenry
b.
choke in series with each power lead.
c.
The In Flight Operable Bomb Rack Lock (IFOBRL) shall be loaded with a 0.030 ampere
suppressed inductive load across pins E and D in series with a 28 VDC power source. Pins G
and F shall be loaded by a 0.010 ampere resistive load in series with a 28 VDC power source.
d.
The mechanical loading configuration of the bomb rack during test shall be NO LOAD.
e.
In addition to the requirements specified in MIL-STD461, the bomb rack shall meet the
following requirements:
1.
The bomb rack shall not emit radiated magnetic fields exceeding Figure 4 of this
document, when tested in accordance with test method RE01 of MIL-STD-462.
2.
The bomb rack shall operate without degradation when subjected to a near-linear
steady-state magnetic field of 1 oersted.
3.
Static magnetic fields. The bomb rack shall not generate a static magnetic field
intensity (H), due to DC, exceeding 1.2 x 10-1 oersteds, at a point 12.0 inches (30.48
centimeters) from the center of the bomb rack magnetic sources. A static magnetic
field is defined as a field which does not change in magnitude or direction during flight.
4.
Dynamic magnetic fields. The bomb rack shall not generate a dynamic magnetic field
intensity (H) over the frequency range from DC to 30Hz exceeding 7.2 x 10-3 oersteds.
The measurement distance shall be 12.0 inches (30.48 centimeters) from the center of
the bomb rack magnetic sources.
Secondary systems. Type I bomb racks only. This test shall be performed at the
4.6.6
following test temperatures:
a.
Room Temperature
-56.7C(-70F)
b.
+70C(+158F)
c.
Perform the room temperature test first. The secondary release assembly and auxiliary
unlock assembly shall be replaced with spare units after each use. Each test shall be conducted as indicated
below.
With the bomb rack at room temperature and the IFOBRL unlocked, cock the LEMA and
a.
linkage assembly, leaving the hooks open. Electrically lock the IFOBRL using rated voltage.
Attach a 101 pound (45.81 kilogram) store to the bomb rack. latching the hooks. Verify that
all is properly cocked. latched and locked. Insert a M55 Ignition Element in the auxiliary
unlock assembly and a MK-17 Mod 0 Ignition Element in the secondary release assembly.
