I am discovering material density issues along with the air supply, buoyancy and control issues inherent to a dry ambient design. In that regard the following excerpt is from the NAVPERS manual for air systems aboard WWII fleet boats, specifically the 3000 lb system.
2A3. Air banks. Each of the five air banks consists of seven flasks, with the exception of the No. 1 air bank, which has eight. Each flask is provided with a drain valve. The total capacity of the air banks is 560 cubic feet. The No 1 air bank is located inside the pressure hull, with four flasks in each battery compartment. The other four air banks are located in the main ballast tanks
The 560 total cubic feet caught my eye and I wondered if this could possibly be correct? Since this is equivalent of seven 80 SCUBA tanks on such a large vessel to blow tons of seawater. I understand the concept of the low-pressure blowers on the surface and would employ that feature. But I am still trying to make sense of buoyancy tankage and air supply issues for a dry ambient design.
Incidentally, I have been dealing with post Hurricane issues (somewhat ?irritating?) but was distressed to see the recent posts, as the animosity was palpable. If as a "new guy" some of my previous posts were somewhat ?irritating? to some, I did so in ignorance of the culture within this community however, I cannot offer any apologies for this reason. Although I am a neophyte in this field, I am an expert in others where the basics were once complex issues to me.
That having been said, I will respect the house ?rules? and limit my posts to those times when the learning curve has flattened a bit as above.
Thank You
