(I have a problem with ADA/HAL/NAL about weight estimation. There is yet to be a product which less than 10% over the designed weight). But just the extra weight will make the IJT sluggish, not really a problem for an intermediate trainer. So I don't think FOC will be held back for weight reduction.
Could this be the explanation for underestimation of weight in preliminary design?

Preliminary design is mostly based on historical data. All such data is from Western world. We don't have any historical data to work with at all. The softwares that are used in Aircraft design are also based on western data. Probably the issue is, these guys can't manufacture various subsystems within the limits that the westerners can make. Plus our engineers have no experience with all this process, so that they cannot even judge on what factor of safety to consider for weights of Indian systems as most of them are being made for the first time.

Any aerospace manufacturer in US has huge amount of data and experience which puts them in better position to judge all such issues. And such data and experience is highly guarded trade secretes so there is no chance HAL/ADA can find it anywhere.

HAL might have made many jets, they might have technical know-hows, but they do not have technical know-why to that level of maturity. Most of the people typically do not understand how much more experience the western aerospace companies and NASA have collected over the last century. The total types of aircrafts they have made could perhaps surpass total number of airframes (of all kinds) made by HAL so far. Its astonishing. And still they end up underestimating weights.

Regarding this weight-reduction consultancy, can't Indian companies like TCS help in this?? They do weight optimization studies for global players for sub-systems AFAIK and do seem to have required competencies. JMT!!

- Akash MK2 will be able to take on any aircraft of today or tomorrow, so first confirmed news from DRDO that there is an Akash MK2
- Also many MPATGMs in development with different ranges


About user trials he mentions started development in 1993, with first units out in 1997. Not the Akash.

Am on smart phone, so unable to find link, BUT, best statement I have come across to date:
We are lagging at a faster and faster pace,” Avinash Chander, head of the department for Defense Research and Development Organisation, a government unit that develops military technology, said this week. “That requires resources commitment as well as a focus on the key areas.”
Maturity. The problem within has been identified and tagged.

We should now experience real progress.

First Woman Director for a DRDO Lab - New Indian Express
The Defence Research and Development Organisation (DRDO) on Tuesday appointed J Manjula as Director of Defence Avionics Research Establishment (DARE), Bangalore. She becomes the first woman director of a Bangalore-based DRDO lab and succeeds P Soundarrajan, who retired last month.

An expert in integrated electronic warfare, Manjula, designated as an ‘Outstanding Scientist’ of DRDO, said her priority will be to indigenise the various electronic warfare systems for the Indian Air Force. “In the next two years, we will work towards building more Indian-made critical systems for various assets of IAF,” she said.

Desi G3OM Makes BrahMos Smarter

Multiple takes:
* "smarter" B'hos
* Covers all angles (as far signals)
* But, most imp: "miniaturising" (IMHO). With every missile trying to be crammed into the bay of a next gen plane, this is by far the most imp feature.
The country on Tuesday embarked on a major mission in miniaturising missile systems by successfully testing a G3OM (GPS, GLONASS, GAGAN on a Module) receiver on the BrahMos supersonic cruise missile. Developed by Hyderabad-based Research Centre Imarat, a Defence Research and Development Organisation (DRDO), the G3OM receiver has been produced by a Bangalore-based private firm.

Sources told Express that it is for the first time that a G3OM receiver has been used in any missile worldwide. “It is definitely for the first time an Indian missile is using such a complex system and to our knowledge, no nation has so far tested it. This paves way for highly miniaturised missiles in future. The G3OM weighs around 17 grams and provides hit accuracy below five meters,” an official said.

Through G3OM receiver, the missile could take target acquisition from American GPS, Russian GLONASS and India’s GAGAN system at one go.

Combined with inertial navigation system (INS), a G3OM receiver could provide very high accuracies even without a seeker.

DRDO has Revenue Budget and Capital budget. Previous year, it was roughly Rs 5000 crore each totaling Rs. 10,000 crore. Now the Capital Budget is practically doubled while Revenue Budget has gone upto Rs 6000 crore totaling around Rs. 15,000 crore which is a pretty good increase. Similar increase of around 50% has been given for Atomic energy and Space programmes also from actual expenses of last year.

Defense Rail Network has been funded with Rs. 1000 crores + Procurement of rolling stock of Rs 275 crores totaling Rs 1,275 crores. Roads and Bridges budget is seeing a massive increase from Rs 5000 crore or so to Rs 15,000 crores.

Naval Dockyard Capital budget has been increased by Rs. 900 crores and OFB Capital Budget has also been increased by Rs. 800 crores.

Any chance some of the road and rail increases are intended to accommodate the Arjun in sectors other than Rajasthan?

That usage is interesting. An Indian would have phrased it as "... transfer technology to India (or Indians) with Indians in charge". Using "the" prefix is a typical gora way of referring derisively/xenophobically to the "others". "The Chinese are coming", "The Japanese are taking our jobs" etc. An Indian coconut seems to have adopted the language of his masters

A bit mischievous though.

It says: Working off 1980s blueprints, India’s biggest state-run weapons maker last year went to the deserts of Rajasthan to test a locally produced piece of artillery. When it fired, the barrel cracked.

The implication is that the barrel burst when the gun was fired for the first time because of bad metallurgy and Indians are not able to develop a gun even when provided blueprints. In fact, the gun had been fired successfully hundreds of times earlier, and the barrel burst was traced to a piece of faulty ammunition. There have been no barrel bursts since, and the gun is almost ready for production. But then, what fun would gora journalists be without their license to twist facts.

The Bloomberg article did have some factual content. It was however pretty negative overall, failing to address the successes that we've had in areas ranging from missiles to aviation to radars to tanks. And yes, they did make the Dhanush trials description sound as if it were caused by faulty design/ metallurgy, which it was not.

One thing for sure: now that the Government of the day is seriously addressing the issues which have debilitated and pretty much made a joke of Indian defence R&D and manufacturing (with some honourable exceptions), the cockroaches, a.k.a. foreign defence industry shills, lifafa journalists and clueless DDM, are all going to come crawling out of their fetid holes to do what damage they can to the defence manufacturing renaissance.

IMHO this is not such a bad thing, at least till we're ready to export, at which time testing and trials will speak for themselves. At this point in time, the less the Western world thinks of our capabilities the better, since in any case they're never going to buy any of our stuff, and that way we might just be able to escape the unwelcome attention of their defence manufacturers and the arms control pimps.

I believe it was Gandhi who said something to the effect of "first they laugh at you, then they ignore you, then they attack you - and then you fight". Looks like we're in Phase 1 now.

The Colonel speaks - http://thebricspost.com/mr-modis-agenda ... 8XJf9PhHa5. Can also be viewed on Ajai Shukla's blog at http://ajaishukla.blogspot.ca/2014/07/m ... razil.html.

The tone of the article is somewhat different from his normal writing style; looks like he's worked to tailor it to international audiences.
During the forthcoming BRICS summit in Brazil, India's new prime minister, Narendra Modi, will push hard for an endorsement of the need to expand the United Nations Security Council (UNSC).

India hopes that its long running quest for permanent, veto-wielding membership can benefit from BRICS support; the bloc includes two permanent UNSC members and three aspiring entrants.

While pressure from BRICS may have limited use, New Delhi’s UNSC prospects would be better served if Mr Modi can return India to a trajectory of robust economic and military growth.

An early indicator of the new Bharatiya Janata Party (BJP) government’s priorities came on July 10th, when its presented its first annual financial budget.

While campaigning for the May 2014 election, the right-of-centre party had railed at border intrusions by China and Pakistan, growing vulnerability to “Pakistan backed terror groups” and waves of illegal immigration from Bangladesh.

To counter this, the BJP declared it would modernize the military, a lip-smacking prospect for the global arms industry, given India’s status as the world’s biggest importer of defence equipment.

The BJP’s election manifesto also undertook to “revise and update” India’s nuclear doctrine, kicking off speculation that it might reconsider, even abandon, India’s policy of “No First Use” of nuclear weapons, or NFU.

The BJP quickly clarified that it was comfortable with NFU, yet apprehensions remained. The manifesto also promised a nuclear force geared towards “changing geostrategic realities”.

It remains unclear whether this referred to a larger nuclear arsenal, or the induction of tactical nuclear weapons in response to Pakistan’s apparent determination to deploy these destabilising and risky weapons.

India’s military spending

The budget disappointed many who had anticipated a wave of buying by India in the global arms bazaar.

Belying its pre-election rhetoric, the government allocated to defence Rupees 2,290 billion ($38.16 billion), Rupees 50 billion ($883 million) more than the outgoing government had provided in its interim budget in February.

By raising defence spending only cosmetically from 1.74 per cent to 1.78 per cent of GDP, Mr Modi signalled powerfully that social spending --- healthcare, education and jobs --- were as vital as national security.

Conspicuously, no additional funds were allocated for arms deals being negotiated, like the nearly $17 billion purchase of 126 Rafale fighters from French company, Dassault.

Instead, most of the tiny spending rise went to the Defence Research & Development Organisation (DRDO), the government agency that develops indigenous weapons systems for the military.

While the DRDO has several successes to its name --- including India’s ballistic missile programme, nuclear powered ballistic missile submarines, and a range of radar and electronic warfare systems --- it has also struggled to develop a light fighter and a main battle tank that have badly overshot budgets and timelines.

Part of the blame lies with the military, which has denied the DRDO funding and cooperation. If, as it appears, the government has thrown its weight behind the DRDO, India could well start producing a larger share of its weaponry within the country.

This would create jobs, a priority for Mr Modi, causing him to extend further support to this initiative.

That the new government regards defence manufacture as a vehicle for job creation, rather than as a firewalled security zone, is also evident from the decision to permit 49 per cent foreign ownership of Indian companies involved in defence production.

The earlier foreign ownership cap of 26 per cent had deterred foreign investment in Indian defence companies, since overseas investors felt that provided little control over the companies they were buying into.

Although the increased limit is short of the 100 per cent ownership that foreign vendors were demanding, it has been welcomed as a step forward.

Yet, these policy framework improvements will serve little purpose without harmonising the military’s force structure.

Flawed military management?

Paying for the army’s bloated manpower leaves little for buying equipment. True, defending thousands of kilometres of Himalayan mountain border needs large numbers of troops. Even so, India is the world’s only significant power that is adding soldiers, its 1.5 million strong military set to rise to 1.6 million this decade.

This even as the threat reduces, with a key potential adversary, China’s People’s Liberation Army (PLA), having incrementally reduced its size by 1.7 million soldiers since 1985.

Currently, the army’s payroll accounts for half its annual budget, consuming thrice as much as the purchase of new equipment.

This obvious conundrum escapes attention because the higher management of defence remains deeply flawed. This is partly a legacy of British rule, when India’s military and police forces were instruments of colonial control; and of the political climate of the 1950s when numerous post-colonial, elected leaders were being overthrown by praetorian militaries.

While India’s military has remained conspicuously apolitical and is repeatedly polled as the country’s most respected institution, it remains confined in its corner with little political interest in its functioning.

The previous defence minister, AK Antony, spent more time troubleshooting for the ruling Congress Party; while the new minister, Arun Jaitley, who is also the finance minister, says he is a temporary incumbent.

With tri-service planning desperately needed, successive governments have feared appointing a tri-service commander, fearing that this would create an undesirable power centre. In the absence of joint planning, the army, navy and air force function at loggerheads, undercutting each other in a vicious contest for budgets, influence and turf.

Despite the military’s obvious shortcomings, India enjoys significant regard as an unusually benign power in a region where a rising China pays scant heed to smaller countries’ sensitivities. Over the preceding two decades, New Delhi has assiduously pursued “multi-alignment”, cultivating strong relations with every regional and global power.

Mr Modi has inherited this equity, but knows that he must back this with discernible muscle, both economic and military. It is this aim that will be guiding his conversations with his counterparts in Fortaleza and Brasilia.

Equipment need not be imported if present policies involving pvt sector with DRDO are liberalized.
Boots on the ground are no longer enough. The name of the game is firepower and the ability to direct it with sensors. That's what counts and which is why the US has routinely hammered its larger opponents in the third world, which have fought blind & with inferior weapons.

Private sector set to enter Indian aerospace market
NEW DELHI: The Modi government is all set to kick-start private sector entry into domestic aerospace arena by giving the green signal to the Rs 13,000 crore project to supply 56 transport aircraft to IAF.

The project was put on hold by the previous UPA regime last year after the then heavy industries & public enterprises minister Praful Patel and some others strongly opposed the move to virtually keep state-run units or PSUs like Hindustan Aeronuatics (HAL) out of the mega programme.

The Defence Acquisitions Council, to be chaired by defence minister Arun Jaitley on July 19, will "ratify" the decision taken to extend the date for submission of bids by foreign aviation majors to August 28. "The in principle decision has already been taken after the law ministry's clearance," said a source.

The first 16 aircraft are to be bought off-the-shelf under the project, while the rest 40 will be manufactured in India to replace the ageing Avro fleet of IAF. The tender or RFP (request for proposal) was issued in May 2013 to over 10 global aviation majors like Embraer, Lockheed Martin, Airbus, Ilyushin, Casa, Saab, Alenia Aeronautica and STE Ukraine, who are to choose their partner or the Indian Production Agency (IPA) based on qualification criteria stipulated in the tender.

The stalled project is considered crucial for the private sector to get a major foothold in the country's floundering defence production sector, which has largely remained the public sector's preserve so far.

India still sources over 65% of its military requirements from abroad, earning the dubious distinction of being the world's largest arms importer. Since he took over as PM on May 26, Narendra Modi has repeatedly stressed the need for a strong domestic defence-industrial base.

The transport aircraft project held PSUs like HAL -- which has a virtual monopoly in the domestic military aviation arena - could not be the "lead agency'' in the programme. HAL, after all, already had "numerous" projects on its plate ranging from production of Sukhoi-30MKI fighters, Tejas light combat aircraft and upgrades of MiG-29s and Mirage-2000s as well as proposed ones like the almost $20 billion MMRCA (medium multi-role combat aircraft) project to acquire 126 Rafale jets. Moreover, after meeting the military requirement, the selected IPA could even manufacture the aircraft for the civil aviation sector.

But in October 2013, Patel had written to then PM Manmohan Singh and defence minister A K Antony to demand that PSUs should get "equal opportunity" and "a level-playing field" in the project. That, in effect, held up the entire endeavour.

Excellent news! But isn't there a lot of Soviet and even Bofors 70s era equipment still lying around that is obsolete? How much of that is going to be replaced?

It seems DRDo is working on railgun:

MODELLING AND SIMULATION OF A RAILGUN POWERED BY A CAPACITOR BANK
S. G. Tatake, K. J. Daniel, A. A. Ghosh, K. P. Tokekar, K. R. Rao, I. I. Khan

ABSTRACT

A railgun powered by a capacitor bank was developed to launch hypervelocity projectiles. The efficiency of the gun to a large extent will determine its feasibility for weapon applications. A simulation code was developed to predict the performance of the railgun. The railgun has been modelled as a time-varying impedance to determine the currents and the voltages from the power source. In the railgun circuit the currents and the voltages are of the order of hundreds of kiloamperes. Even very low impedances of the order of milli-ohm and micro-henry are substantial sources of energy losses. The measured and simulation currents at peak values agree with in 10%, validating the model. The simulation code accurately predicts the energy distribution in the system. Maximization of the projectile energy leads to improved and efficient designs. The simulation also leads to the optimized launcher pressure and payload velocity.

CSIR- National Aerospace Laboratories conferred with Best Laboratory Award 2014
CSIR-NAL has successfully carried out the drop tests of BRAHMOS-A from Su-30 MKI model in 1.5 m Low Speed Wind Tunnel to estimate the actual trajectory of the missile at different conditions of the aircraft in a record time. NAL has also successfully conducted the captive and isolated strain gauge tests to generate highly accurate data needed for the BRAHMOS Air-Version project in Tri-sonic wind tunnels. It is noteworthy to mention that the Dynamic Store Separation Trials have been successfully conducted for the first time in the country

I have stopped following shukla for a while. His loyalties are in big doubt after the VKS episode anyway.
