Frigate:FFS,radar,stablizing fins etc

1.FSS and look slike a small fish boat on radar

It is official ---RSS Formidable,FFS 68!
What does FSS stand for?
Frigate Ship Singapore?
Frigate Small?

2.Rotating Radar

3.Stabilizing fins--first in RSN

4.Anchor cover

5.Stealth technology

6.Shipmaster platform management sys

7.CCTV and Gap

Farking freakish stealth frigate... Laughing

Jking, maybe it stands for Future Frigate System?

YI SG

What does ffs stand for? small frigate. Mr. Green

kotay SG

FFS, then FSS, then FFS again and then FSS again ... ??

FFS ... For Farks Sake! ... Rolling Eyes

Anyhoo, my guess ...

FF = Frigate
S = Stealth

lionnoisy,

Dude, point 5 ... I don't think the scans you put up relate to the Formidable at all.

"Use of Waterjet propulsion to minimise vibration and noise" ... huh?

kotay SG

Actually, 3000 odd tons is pretty standard displacement for a frigate ...

Small will be 2000 odd tons and large will be 4000 plus tons.

2.It is very relevant.can experts here tell us how Waterjet
can reduce vibration and noise.

kotay SG

I'm not saying the point is invalid per se ... just that it's not relevant to the Formidable frigate.

The Formidable class uses constant pitch props ... not waterjets. hence the Rolling Eyes

The shroud over the propeller blocks most of the noise and cavitations.

Imagine a fan with a short over it. Most of the noise will be blocked.

Would you please stop this nonsensical posting of this? What are you? A retarded spambot?

Water jets do not use propellers.. no shrouds too. Instead, they use 'impellers' and are housed in a 'housing'.. Smile

Fingolfin_Noldor SG

It isn't exactly a propeller but something similar. An impeller is a small propeller. There isn't anything else that can drive water at a high pressure outward. I have yet to hear of a water pump capable of driving water at speeds fast enough to push a 4000 tonne warship.

It has a shroud which is the housing. The Housing act as a sound absorber.

There's a nice drawing here: http://en.wikipedia.org/wiki/Water_jet_%28propulsion%29

re:papa 5 in my opening posting:

2.It is very good indeed for PV in RSN.I think
RSN taps on PV experiences.

The PVs are also installed with the water-jet propulsion system. Unlike propeller-driven vessels, the water-jet system enhances the manoeuvrability of the PVs, produces less noise and is more economical and easy to maintain.

Hi, here is a link that I believe explains waterjet better. If I'm not wrong, RSN uses their jets.

Waterjets are indeed large waterpumps.. Cheers. Smile

2.thanks for info.

It’s not all hamilton … Don’t forget Kamewa …

Fingolfin_Noldor SG

I believe we use Kamewa for our boats in general.

Fingolfin_Noldor SG

With a small propeller/impeller/orwhateveryouwanttocallti inside......... if you actually looked at the picture properly...

Any1 notice tat everything tat produce noise r mounted on shock mounts

lionnoisy SG

can the FFS make a 180 degree turn in a length 3 times of her size,like PV?
