Well I guess everyone is busy with football or clean up after Ike, or something else to answer Darrin's last question about the HP air system. So since it's been a few days since anyone chimed in and I'd rather be reading through my Fleet Type Submarine Manual than watching football - here goes a long winded answer:
The 3000 lb HP air system consists of two HP air compressors, located in the lower flats of the After Engine room; HP piping that runs from the Forward Torpedo Room to the After Torpedo Room; HP air manifolds located on the starboard side of the Control Room; and a series of HP air banks that are located inside of the Main Ballast Tanks.
Each HP air compressor has a capacity of 20 CU FT per hour at 3,000 psi. The HP air compressors discharge into the HP service line to the Receiving Manifold and then into the Air Banks for storage. In addition to the HP Air Compressors there are two topside HP Charging Connections on the port and starboard side of the sail
There are five Air Banks consisting of 36 air bottles. The #1 Air Bank has 8 air bottles, and the four Air Banks have 7 air bottles each. The Air Banks are located in MBT 2A, 2B, 2C, 2D, and MBT #6A, 6B, 6C, and 6D. The air bottles are installed upside down to prevent moisture build up inside of the bottles. The Air Bank Receiving and Supply lines are fitted with hull stop vales where the piping pierces the pressure hull and are used to isolate the piping if needed. The total capacity of the Air Banks is 560 CU FT.
The HP Air Manifold is made up with one Receiving and two Distribution HP Manifolds. The Receiving Manifolds receives HP air from the two HP Air Compressors and directs the air to the Air Banks. When HP air is needed the same piping is used to the Receiving Manifold to the two Distribution Manifolds.
The Distribution HP Manifolds direct air to the Safety and Negative tank blow lines, the MBT Blow Manifold, the hydraulic accumulator air flask,, the HP air Bleeder, Bow Buoyancy tank blow line, the 225# Service Air system, and the Forward and After 3000# Service air lines.
The 3000# Service Air lines supply air to the Forward and After Torpedo Rooms, to the engine starting flasks, and to the Reducing Valves in each engine room to supply the 500# air to start the diesel engines.
So what’s missing?
