To all, I have a problem I would like to solve and I need help. Just some background info to start. I was a member of the crew aboard the Scamp SSN 588 the sister ship to SSN 589. Ever since she sunk I have always wondered why she sunk. Now I believe there is a viable answer to this question. An acoustics expert has listened to the sounds of her demise and is convinced that a hydrogen explosion in her battery compartment caused her to ultimately sink. His scenario goes like this. During battery charging one of the battery terminals overheated and melted and caused a spark that ignited the hydrogen in the battery compartment. The force of this explosion, he estimates that 2 explosions of 20 lbs of TNT each approximately .5seconds apart, damaged the interior superstructure to the extent that it disabled/killed the crew and she started sinking, from there it took approximately 22 minutes till her pressure hull collapsed. To see an internal view of her watch this video, at the end of the video you can see how her wreakage was strewn over the ocean floor.: http://www.youtube.com/watch?v=0fPxtFVl4Gs&feature=related Too see the report go here: http://www.burtonsys.com/USS_Scorpion.html Looking at the interior of the sub, the batteries are in the bottom compartment next to the keel under the crews quarters, above that is the officers quarters and mess hall, above that is the control room, sonar shack, yeomans shack and radio room. Forward behind a water tight bulkhead is the torpedo room aft is a fuel oil tank for the diesel engine that helped with radiation protection from the reactor compartment aft of it, then the engine room then the steam generator compartment. So it goes like this: Torpedo Room /Bulkhead/ Control compartment /Oil Tank-Bulkhead/ Reactor Compartment /Bulkhead/ Engine compartment /Bulkhead/ Steam Generator Compartment- Shaft Alley/ Propeller with a water tight boot of course. Now to my problem. Could 2 explosions equivalent to 2 20 lb TNT detonations (.5 seconds apart) cause enough damage to totally disable/kill the crew. I know this is a daunting task and that a scale emperical model would be financialy unfeasible but, is there a modelling program out there that could model this event, and if so, who would volunteer ;-) Also, does anyone have any information about the force that 20 lbs of TNT can generate?
