The acoustics under the B-1B are -terrible- with high pressure vortices flows that curl up around the glove root and beat the skin with something like 170 decibels of constant thumping. Tore the AGM-86 to pieces. The AGM-129 was designed to handle the aeros environment but the drag on the jet became so bad that it could neither make range nor refuel at a safe height

The 1B would probably run out of fuel trying to dash supersonic with all that drag...
Still waiting for a source.

Probably not going to get one. Everything forward of the nacelles was pretty benign, the flow aft of the nacelles was pretty challenging. If we had problems with a separation test on the Bone chances were it was an aft bay test. Got to see some pretty interesting video back in the day of aft bay tests...

I could see air getting all jammed up with 6 abreast as well as the 2 nacelles. Maybe that's why they're sticking to in-line only, and going with bigger weapons. :confused:

We got the dirty air with nothing on the pylons. The test accel. to field Sniper paid a lot of attention to safe separation. The final mission, which I was the test conductor, was a GBU-31 out of the aft bay at .94M and 1,500 ft AGL. It came out clean and the rest is history. If everything were so easy...

sferrin, you wil find some information in this document. The rest is gleaned from memory in documents and interviews probably no longer found online.

Good find Rooster, the info is on page 37. The high acoustics were high speed and low level 165 dB. Not surprisingly aft stations the worst, downstream of the tunnel right next to 4 exhaust nozzles.
