For relatively short period such as 30 days, as underwater operation depends on AIP, LAB-AIP-submarine may show better performance than LIB-submarine. But, performance difference between LAB-AIP-and LIB-submarines is not bigger than that between LAB-AIP-and LAB-submarines.<br /><br />For longer period such as 60 days, liquid oxydgen is consumed and half of this period is dominated by LAB. As a result LIB-submarine may show better performance than LAB-AIP-submarine.<br /><br />As output of AIP is low, high speed performance is dominated by batteries (LIBs or LABs). LIBs-submarine shows much better performance.<br /><br />Regards<br /><br /><br /><br />Anonymousnoreply@blogger.comtag:blogger.com,1999:blog-19245896.post-8216808348557199412017-02-12T01:39:02.319+11:002017-02-12T01:39:02.319+11:00Hi Pete
I estimated performance of LIB-submarine ...Hi Pete<br /><br />I estimated performance of LIB-submarine (LAB-submarine) as follows:<br /><br />Nominal voltage per unit battery-module [1]: 36 (2)V.<br />Submerge period at 4kont/h [2, 3]: 7-9 (3-3.5) days<br />Acual submerge peiod at 4knot/h [4,5]: 6-8 (1-1.5)days<br />Output hold period for sbmaerge at 18knot/h: 3-4 (1) hours<br />Recharge time very short (long)<br />Charging frequency for 60days-surveillance 8-10 (40-60) times<br /><br />[1] Values are based on various data for LIBs and LABs. LIB-modules (LAB-modoles) are connected in parallel (series) for generating voltage of nearly same maginitude<br />[2] Data of LABs are basted on reported simulation of varioue submarines.<br />[3] Data of LIBs are based on comparison with those of LABs.<br />[4] As complete discharge shortens life of battery, I assumne 90% (30%) of capacity is discharged in actual submerge by using LIBs (LABs)<br /><br />Regards<br /><br />Anonymousnoreply@blogger.com
