Kockums scaled existing Swedish designs up to the Collins. But the Collins still had many scale problems.<br /><br />[1] https://en.wikipedia.org/wiki/Barbel-class_submarine<br /><br />Have a happy new year.<br /><br />PetePetehttps://www.blogger.com/profile/02624742078679760819noreply@blogger.comtag:blogger.com,1999:blog-19245896.post-48155489958376058332016-12-26T20:53:57.136+11:002016-12-26T20:53:57.136+11:00Hi Pete

One of the key elements in conventional s...Hi Pete<br /><br />One of the key elements in conventional submarine is diesel generator. As the diesel engine for submarin is highly demanding, diversion of diesel engine for merchant ship is difficult and cost of development is extremely high. That’s why multiple arrangement system of existing diesel engines is adopted for conventional submarine [3].<br /><br />A four-stroke engine these occur in two complete revolutions is used in modern conventional submarine, because it has exhaust and compression functions needed in snorkel operation and in low rotational range at strat-up, respectively. In a two-stroke engine, the four "cycles" of internal combustion engine theory (intake, compression, ignition, exhaust) occur in one revolution-360 mechanical degrees, and more than one function occurs at any given time during the engine's operation. As a two-stroke engine itself does not have exhaust and compression functions needed in snorkel operation, it is not suitable for application in submarine. Gas turbine engine needs as huge compressor as the diesel engine, and is not suitable for application in submarine [1, 2].<br /><br />Repeated snorkeling of submarine results in the severe operational conditions such as generation of transitional thermal stress caused by rapid local heating, rapid increase in sliding and lubrication of engine parts and immediate stop at detection of danger. As operation of diesel engine means generation of noise and vibration, user of submarine tries to minimize operation period [2, 3]. <br /><br />[1] Perfect Guide of Submarine Mechanism by Tadashi Sano<br />[2] https://en.wikipedia.org/wiki/Two-stroke_diesel_engine <br />[3]SHIPS OF THE WORLD, 2016, November, No848, page 84 “Propulsion System of Modern Submarine” by Masakazu Kaji, the Ex-commandor of Submarine Fleet and the Vice-admiral.<br /><br />Regards<br /><br />Anonymousnoreply@blogger.comtag:blogger.com,1999:blog-19245896.post-71856506746575637332016-09-29T08:36:12.947+10:002016-09-29T08:36:12.947+10:00
Hi Pete
Sputniknews introduced opinion of Russia...<br />Hi Pete<br /><br />Sputniknews introduced opinion of Russian defense expert, Dr. Vasily Kashin on submarine technology transfer from Japan to Taiwan. Dr. Kashin clearly denied possibility of the submarine technology transfer (Dec/09/2015, https://jp.sputniknews.com/japan/20151209/1290996.html).<br /><br />Only USA can challenge China by anticipating the Submarine Project of Taiwan. USA can obviously assist Taiwan by joint project, combat and sonar systems, but, issues on energy system and structure elements which are diesel submarine specific are yet solved. Also, in US, there are very strong opponents against introduction of non-nuclear submarine, who refuse any investment or technology development of manufacture of non-nuclear submarine.<br /><br />As Japan has many problems with China, the Japanese government will never make a decision which evokes the harsh confrontation with long-term Chinese government. <br /><br />Indigenous development and building project of the submarine, while drawn foreign technology, is possibly to be implemented. If USA anticipates the project as a major partner of Taiwan, she would be to undertake herself the huge criticism from the Chinese government. Possible partners except Japan are France, Germany, Sweden, etc. Japanese submarine is too big for Taiwan. However, it is clear that every effort to prevent leakage of secret contract will be made.<br /><br />Regards<br />Anonymousnoreply@blogger.comtag:blogger.com,1999:blog-19245896.post-27903506515523096982016-09-22T01:27:29.585+10:002016-09-22T01:27:29.585+10:00Hi Pete,

In fact, I think Japan should offer Taiwan technical help in reverse engineer the Hai Lung-class submarine.Nickyhttps://www.blogger.com/profile/15318590507921043958noreply@blogger.com
