^ Maybe one line for refit and maintenance of existing 209/ Scorpene so won't be parasitic of the new builds.

dinesh_kimar

^ The missile program used the technology available at the time.A2 was already in service, and based on SLV3 with existing supply chain , so A4 building blocks were in place and could be quickly realized. My speculation is that its easy for DRDO to produce and launch A4, so we have maximum launches ...

^ Tatra ToT was acquired in 1986 from Omnipol of Czechoslovakia. Neither Omnipol or Czechoslovakia exist anymore, but we still pay abt 60% Foreign exchange per truck to some entity bases in Europe collecting on its behalf.

^ From Jayasimha's post: it's bleddy unbelievable. They want to indigenise BMP 30mm ammo , after building it from 1989. Other items listed are "baseplate" and " springs". There's even a searchlight. This isn't deep slumber, its coma. And the solution isn't to privatize. Didn't wo...

^ Saar, I really appreciate this government which makes us all lion hearted and question every decision. During the "dark decade" (applied for copyright :)), I certainly used to keep mum. I was fearful that any protest from me would be faithfully tracked up to zilla panchayat and ward leve...

in tank armour front the cast turrets are said to be weaker than welded turret ? Yes saar. Welding joint can be stronger than the base metal structure, in some cases. Casting is used to make a complicated shape quickly ("net shape" as Ramana gaaru has explained in the past), but with weak...

^ i think its the routine A5 test, which HK Rout had tweeted abt earlier.
The K5 ,as per tradition, would be tested on an underwater pontoon off Vishakapatnam, and not from the ITR.

dinesh_kimar

^ tsarkar sir, he is right. DRDO has produced a variety of steels, incl. non- magnetic steel for submarine use. This was along with one of the SAIL plants. Seems possible.

dinesh_kimar

^ I'm sure he's right. I was thinking same radar complex mounted on tatra, tata and Ashok Leyland.

dinesh_kimar

Many conventional military factors – including the localised nature of the stand-off, recurring contexts of territorial tussles, China’s own apprehensions about being seen as a bully and habitual land ‘aggrandizer’, and the diplomatic burden of hosting the BRICS Summit – might have been reasons for...

^ The above video talks abt "Permasyn" motors , which, IIRC, is made by Siemens. The 2 x diesel engine comes from MAN. So looks like significant German input in the "move" category.

dinesh_kimar

I'm sure CFM has given ToT for the engine, in exchange for C919 supply of abt 1000 engines. ToT in form of consultancy, testing, data bank access and yes-no type answers, but not actual core. Maybe a clause such as "135 Kn thrust with a MTBO of 2500 hr is CFM's responsibility, measured on flyin...

^ OT, but even France cannot make all types of engines. Their larger powerplants have collaboration from RR and GE. If kaveri becomes reliable and starts flying, it can be the basis for a 100 seat passenger jet, for example, in somewhat modified form. Apparently, GTRE designed the Kaveri with 7 engi...

^ river in South India flowing better.

- More thrust obtained from engine ?

- I wish Sjha or Siddique sahib come out with some news / white paper at end of year on such small things as thrust/ weight / reliability / future plans.

dinesh_kimar

^ AK Sir, you are right. However, being an army brat, I request we not talk negatively abt fellow Officers (Gen. Bewoor) . As one poster said, no more blue-on-blue. The situation , as i understand , was something like this. After 1962 war defeat, the IA had opened its eyes to a possible 2 front war....

dinesh_kimar

DRDO's techfocus has some info on K4 SLBM, whose aluminium nose cap dome is " now made by Hindalco, proved in a K4 slbm test in 2014, and validated in other tests." Specifically Mentions a 2017 flight trail of K4.

Deliberately put by DRDO to send a message that K4 production started ?

dinesh_kimar

^ what this means in layman terms pls?

dinesh_kimar

^ Saar, while i agree with all your points and am one of your many admirers, isn't it my duty to remind you that you yourself have said that the submarine tragedy happened cause of a torpedo explosion during loading in the dockyard ?

dinesh_kimar

^ Continuing from my earlier post, is there a possiblity that 68-70 KN Kaveri is integrated into the LCA ? > Role of LIFT / Combat Hawk / CAS /recon > Aircraft wt. reduced for extra seat and to maintain power-wt. ratio - ballast, radar and fuel load sacrificed. IFR obviously stays. > Engine MTBO 400...

dinesh_kimar

The LCA bottleneck - its F-404 engine is sanction prone. I understand from BRF that we are past the hump on all other aspects incl. radars. Taking a leaf from China's book, the LIFT and ground attack versions should be a different engine (made in parallel with "regular" versions). China ex...

dinesh_kimar

What is most puzzling is we had access to U-209 blue print (which is considered one of best post cold war diesel submarine designs) and could have continued building it and improving on it. I read somewhere that the front hull shape / dynamics is patented by HDW and we cant copy it. The Germans app...

^ OFB has a pic of 5.56 MG, apparently INSAS based. Looks different from the belt fed 7.62 mm MAG version.

^ Gen. Sagat probably pioneered joint IA-IAF Ops. He was one of first commanders to use helicopters in warfare , and transports as bombers (DH-4 Caribou).

dinesh_kimar

^ Ever since Doklam, there has been an impression created by some posters that there was some kind of power struggle between Xi and the PLA, and when Xi's faction won, Doklam was resolved. This may not be entirely true: 1. When Gen VK Singh visited Tibet as Eastern Army Commander, he spoke (wrote) a...

^ China can fool with us and protect Masood Azhar. We don't have a stick to beat them with. They have a number of weak spots - restive provinces teeming with fine upstanding islamic law abiding types , Tibet , internal conflicts due to communist ideology, people displaced due to lop sided growth, gr...

^ MP has not been gagged, can easily state that "LCA essential to our nation's future, min. 200 orders required." My take : IAF fears that LCA testing will take abt 8-10 years more, up to 2030 and SE can start coming in by 2020. They must have made their choice. The MK-1A, though better th...

dinesh_kimar

^ Very good points from Chola Saar. His earlier post abt trying for a simpler R-25 class turbojet got me into " search" mode. Some points : > Kaveri is very good effort by GTRE folk. Equivalent to an early mark of Snecma M-53 which was fielded in 1983-85 period. The later (current) engine ...

^ To all Gurus (Philip Sir, Indranil, etc.) we have bought Harpoons for Type 209 submarines. It is possible to fit them on only 2 subs, the latter 2 which were assembled locally. Some literature on the Harpoon suggests that it is compatible on all NATO 553 mm tubes. Why is this may I ask?

dinesh_kimar

^ I readily admit to my ignorance on HAL Dhruv, all posts were speculative in nature. My interest is in the following: > With the Shakthi engine, we have a 1250 hp capability, with growth potential to 1700 hp. This is the same as a Seaking. SO can we build a Seaking class machine ? > When searching ...

dinesh_kimar

^ Raghuk, i understand where this is coming from. I clearly say that cyclic is part of "MGB-rotor system" in my post. You cleverly say that cyclic is not part of MGB but is part of rotor system. then accuse me of "spread false statements as facts". I request you to clearly bring ...

After all these years of lurking, my fave among all brf posts remains this:
My aunt with a d**k is my uncle.

It never fails to crack me up on cold wintry mornings when things seem bleak.

^ Shiv Saar, i had a good laugh abt your points while having breakfast.

Its not so easy to collect proof and give a point to point to the above.

dinesh_kimar

^ Saar, IMHO, HAL's fix of the gearbox is controversial. 1. A 2-stage Main Gear Box was decided during ALH design phase, when the technology collaborator (MBB and ZF Transmission, both from Germany) had little experience for such a design at the higher power ratings of Dhruv.(Apparently it is "...

^ I will try to answer Indranil's post, though not an expert. Below stuff is speculation. The typical Helo gearbox is complex. (Eg. Mi-17 Gear box is heavier than the engines) .It has following features: > to have a reduction of 1:100 within tight weight and volume limitations. For example, if gas t...

^ Ka-226 seems to be a quid pro quo for deep ToT by Russia. Otherwise, doesnt make sense.

IA has apparently deployed a few Bofors guns in Siachen. The guns cannot be brought back , and will be abandoned after end of life.

On This day, fifty years ago, the GOC of 17 Mountain Division, Lt. Gen. Sagat Singh (then a Major General) disobeyed orders and refused to vacate the strategic Nathu La pass in Sikkim, as demanded by the Chinese......and agreed to by certain Indian "higher ups". At the time, India was not ...
