The launcher will be mounted on a 14-inch suspension bomb

4.6.2.2 Shock.

rack or simulated bomb rack having 14-inch suspension provisions and sub-

jected to three shocks in each of the positive and negative vertical and

longitudinal axes for a total of 12 shocks. The verical half-sine shock

pulses will have a peak of 10 +0.5g and a 60 to 80 ms duration. The longi-

tudinal half-sine shock pulses�will have a peak of 13.5 +0.5g and a 60 to 80

ms duration. Calibration of shock producing apparatus w~ll be accomplished

by using a dummy test specimen and achieving two consecutive shocks of the

required shape, amplitude, and duration. The applied shock will be measured

midway between the attachment lugs on the bomb rack using an accelerometer

with a flat frequency response within +10 percent from two to 20 Hz. The

accelerometer will have a transverse s~nsitivity of not greater than five

percent, and an amplitude linearity within 10 percent from five to 100

The shock analysis system employed

percent of the peak acceleration amplitude.

will not allow more than a five percent measurement error into the frequency

band of two to 20 Hz.

If filters are used, they will have linear phase

shift characteristics and a pass band within one decibel from two to 20 Hz.

The tests will be performed with the intervalometer in the armed position

with no power applied. The intervalometer index position will be noted before

and after each test. The launcher will meet the requirements of 3.4.2. Upon

completion of the shock test, the tests of 4.6.1.1, 4.6.1.2, 4.6.1.3, and

4.6.1.4 will be performed. The launcher will meet the requirements of 3.3.1.1

through 3.3.1.4.

4.6.2.3 Transportation vibration. The launchers (which will include the

number of test samples shown in Table II or III, as applicable) will be pal-

letized in accordance with WR-54/174. The pallet will be vibrated along each

of its three axes for 45 +1 minutes of sinusoidal excitation covering the

frequency range of five to 200 to five Hz in 15 �1 minutes at a constant amp-

litude of 1.5 g PA. The series of tests will be run once with the launchers

at +60 �3�C (+140 �5�F) and once with launchers at -40 �3�C (-40 �5�F).

Total time of vibration will be not less than 4.5 hours: The intervalometer

index position will be noted before and after the test. The launcher will

meet the requirements of 3.4.3.

Upon completion of the test, each launcher

will be subjected to the tests of 4.6.1.1, 4.6.1.2, 4.6.1.3, and 4.6.1.4.

The launcher will meet the requirements of 3.3.1.1 through 3.3.1.4.

4.6.2.4 Flight vibration. The launcher will be mounted on a 14-inch

suspension bomb rack or simulated bomb rack having 14-inch suspension provi-

sions and subjected to the following two tests as-specified in-4.6.2.4.1 and

4.6.2.4.2 in accordance with Tables II or III, as applicable. Electrical

contact between any detent contact arm and pin E of J1 or J2 will be continu-

ously monitored during the test. The intervalometer index position will be

noted before and after the test. The launcher will meet the requirements

Upon completion of the test, the launcher will be

of 3.4,4.1 and 3.4.4.2.

subjected to the tests of 4.6.1.1, 4.6.1.2, 4.6.1.3, and 4.6.1.4. The

launcher will meet the requirements of 3.3.1.1 through 3.3.1.4.
