Abstract:

An acoustic test program was conducted on the AIG section of the B-2 pod of an Atlas Missile from 22 January 1964 to 24 March 1964 in the reverberant chamber. The test program consisted of a series of noise reduction tests to establish the effectiveness of various acoustic modifications to the AIG pod and the ARMA computer. Each of the modifications was assessed as to its contribution in reducing the noise energy level at the diode circuit boards in the ARMA computer. A noise reduction at the circuit boards of at least 10 decibels below the baseline configuration for all frequencies from 300 to 10,000 cps was desired. The baseline configuration consisted of two inch thick fiberglass completely lining the interior surfaces of the AIG pod. The purpose of the Acoustic Test Program was to establish an improved operational pod configuration to obtain this additional noise reduction in the ARMA computer.
