Revised Table Comparing Iranian, Russian, German, French & Japanese Submarine Diesels

Since Anonymous produced Table Comparing Russian, German, French & Japanese Submarine Diesels of March 15, 2018 Anonymous has added the Iranian Ghadir-class submarine and added and/or revised figures indicated in Blue. Some fields (like Country, Make and Type) could only fit in vertically.

Enjoy this super Table of Specifications of modern diesels for submarine

[A] Specification of diesel of Ghadir-class, Iranian midget submarine is very roughly estimated. Mechanical output of Ghadir diesel is around 100kW.

[B] Net mean effective pressure demonstrated high performance of DM-185V12. 12PAV200SMDS needs further improvement. 

[1] Piston speed = Stroke x Rated speed / 30000

[2] Based on product catalog or data from this blog.

[3] [9] page 3,” Table 1 Performance and emission targets DM-185 Engine Family”. Others are based on product catalog or data from this blog.

[4] Cylinder capacity = (Bore/2)^2 x Stroke x 3.14 / 1000

[5] Pme = (600 x SkW)/((3.141x d^2/400) x (s/1000) x n x Z / 2)                                                                                                                                                                                                   
[6] Electrical output of DM-185V12S = Electrical output of DM-185V12G x 0.8. Electrical output of DM-185V12G is in [11]. For others, Electrical output = Mechanical output x 0.8 (= power factor)

[7] Electrical output at snorting = Electrical output x 0.9 (= assumed figure based on [8]).

[11] Ibid, page3, [9] page 3,” Table 1 Performance and emission targets DM-185 Engine Family”.

[12] Hypothetical DM-185 diesel generator for submarine applications. All data of DM-185 12VS are estimation.

[13] Specific electrical output =Electrical output per unit capacity = Electrical output / (Cylinder capacity x No. of cylinder)

[14] IR = Iran, Ru=Russia, DE=Germany, FR=France, JP=Japan

[15] https://en.wikipedia.org/wiki/Ghadir-class_submarine Ghadir-class sub is based on the North Korean Yono class submarine (https://en.wikipedia.org/wiki/Yono-class_submarine). As there is no information on diesel of Ghadir-class, estimation of its features is based on various assumption as follows:
(1) Diameters of intake tubes are ca.20cm and 60cm for Ghadir and Soryu based on pictures, and the Diameter reflects bore size. 
(2)  Considering low vibration and size of submarine, L6 diesel is used.
(3)  Maximum rated speed is 2000rpm [16], because of long intake tube.
(4)  Volumetric efficiency is maximum at 7m/s of piston speed.
(5)  Net mean effective Pressure of modern diesel is 1.6-2.0MPa 

[17]. Assumptions (1)-(5) and try & error results in data on Ghadir diesel.

Thanks KQN

The article "Radiated Noise Signature of Modern Diesel Submarines" by George Papangelopoulos at Naval Analyses website is very well written - see http://www.navalanalyses.com/2018/04/radiated-noise-signature-of-modern.html?spref=fb

I was unaware of Naval Analyses' existence http://www.navalanalyses.com/ but see it has been going strong since 2014.

Regards

Pete
