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

Piston speed = Stroke x Rated speed / 30000

are based on product catalog or data from this blog.

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]).

[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
ReplyDeleteThe 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.
