India's R&D in Defence DRDO, PSUs and Private Sector

[Thakur_B]

My fault. I meant the HPR type ones. 12 of those iirc. I wonder if an MPAR style system is being looked-at.

Here you go. Its like a 4 panel Arudhra, with 50% greater performance.

EL/M-2084 substitute ?

[Karan M]

Well we need a lighter weight antenna, a gimbal and the aerostat to hoist it all up.

[Karan M]

The meta-material is DRDO funded project and specification/requirements were laid down by DRDO.

They will want to figure out a way to embedded these material on to a composite skin of aircraft and the effect of high speed and air friction/heat on these material.

Good find. Any link?

This page has the image of the professor along with the specification of the frequency it is effective. If you have an account, then you can see the large format of the image with the all the details.

[Karan M]

Ok, thanks this is really credible stuff and designed for practical application. If they can integrate this into the composite skin of our aircraft, even as secondary layer.. great stuff. Thanks to AmberG and you for flagging this.

Something I was trying to get confirmation. SSPL's GaN X band effort.

This video confirms SSPL has X band GaN HEMT for RF at 5 watt in 2017. If I am not wrong 10-15 Watts would allow us to use GaN in fighter radar.
There are some info floating on internet that we have reached 10 watt and GAETEC is able to repeat the process. Cannot confirm.

At 3:55

If they have managed to make S/C/L Band GaN devices in bulk, its possible they do have an AWACS India antenna populated and ready for tests. GaN had achieved 10W/mm @ 50V as of 2017. They didn't have X-Band at the time but were trying for it, and had managed till L/S/C. Looks like they then delivered 200 HEMTs at C/S/X band at 5W/mm for tests. This combined with the DRDO's stated plans for their AESA architecture clearly explains why they aren't yet mucking around with exotic bands for their radar programs. Simply put we don't need to. Really remarkable how far we have come from such a limited footprint of 1x homegrown radar in the 1980-90s.

Just to reiterate how rapidly DRDO has leveraged successful programs across different radars. The S-Band TRM tech developed via the AEW&C, and then the matured tech. fielded via Arudhra has led to Ashwini, and then ADTCR, and now the Mountain Radar & HPR programs. I am fairly certain the C-Band tech will be used for WLRs or Akash NG and they are being used for the QRSAM, while we know the X-Band GaAs modules have been used for Uttam, the QRSAM and the ADFCR.

The next tranche of development will really be interesting as we are aiming squarely at what the bigwig in the field is fielding.

[Karan M]

DRDO is really rocking the frugal engineering mindset using the scale offered by the engineering bench strength in India. For a fraction of the cost allocated by WW bigwigs, they have been developing system after system. Now for that same stuff to be replicated across missiles.

https://salute.co.in/military-modernisa ... air-force/
AM Nambiar:

We are in the development stage of the Pralay—a guided short-range (400 km) tactical ballistic missile for battlefield use developed by DRDO. Also developed for the IAF are the precision guided munitions (PGMs) Garuthmaa and Garudaa. An air launched anti tank missile has been developed called SANT (Stand off Anti Tank) which will have multi-platform launch capability and can be launched from attack helicopters. Other weapons developed are the SAAW (Smart Anti Airfield Weapon), Dhruv Astra an anti surface missile and a new generation anti radiation missile—the Rudram-1. We also have the Rudram-2 and Rudram-3 missiles which are variants of the Rudram-1 with different functions for ground attack.

That's 9 missiles/PGMs being developed in one go for the IAF, pretty much covering the entire gamut of their needs. Add to this the GP bombs, Astra & Nirbhay.

Tragic news:
What caused blast? Confusion on IISc campus

A pall of gloom descended on the Indian Institute of Science (IISc) campus, where an explosion at the Laboratory for Hypersonic and Shock Wave Research (LHSR) claimed the life of an engineer, and critically injured three others. The blast, which occurred around 2.15pm, could be heard across the campus, according to students who gathered at the lab to find out what had happened.
As news of the blast spread through the campus, there was confusion, especially among those who work and study at the department of aerospace engineering. No one seemed to be able to pinpoint what exactly caused the blast, and theories began doing the rounds. The force of the blast was enough to blow away every window of the lab and even affected the roof, which is at least 20 feet high. “Such a blast can occur only with the presence of a fuel,” said one anxious student from the department.

Super Wave Technology Private Limited, a startup founded by Professors G Jagadeesh and KPJ Reddy, from the department of aerospace engineering, was housed at the Laboratory for Hypersonic and Shock Wave Research, and was working in the area of shockwaves and how they could be applied to daily situations as well as industrial ones. They have earlier delivered solutions which allow for drug patches which deliver vaccines, insulin and antibiotics through shockwaves, instead of injections

[Karan M]

This sort of stuff happens. Its regrettable but also reiterates that people toiling silently in the background often take great risks.

I still remember meeting an old Bengali gentleman from DMRL, a senior scientist, who was overjoyed to have people genuinely interested in what he did for "Mother India", he mentioned how once he left an experiment in his lab and went out for a bite to eat, only for it to explode and take out his lab. Devoted to the cause and his patriotism was eye-opening in an era where it is "un-cool" to be nationalistic and any such beliefs are "toxic", "hyper-nationalistic", "jingoistic" etc. Yet, there he was having dedicated his life to ensure India got some breakthroughs in an esoteric field. We are lucky that way.

If they have managed to make S/C/L Band GaN devices in bulk, its possible they do have an AWACS India antenna populated and ready for tests. GaN had achieved 10W/mm @ 50V as of 2017. They didn't have X-Band at the time but were trying for it, and had managed till L/S/C. Looks like they then delivered 200 HEMTs at C/S/X band at 5W/mm for tests. This combined with the DRDO's stated plans for their AESA architecture clearly explains why they aren't yet mucking around with exotic bands for their radar programs. Simply put we don't need to. Really remarkable how far we have come from such a limited footprint of 1x homegrown radar in the 1980-90s.

On DRDO's website, they have claimed to have L/S/C TRM at 400W. DRDO chief in one of the interview mentions that GaN S band is at 40W, targetting 110W to allow them to apply for radar. So 400W must be L band.

10W @ 50V is at X band. I don't know if they have TRM for X band. They would targetting for atleast 20W. Equivalent power rating to GaAs 10W X band does not provide any advantage and will be expensive.They would only go for it, in case the criteria is to get more range for the same onboard. Once they achieve 20W or more, it is worth using GaN.

Given the cost factor, I would expect GaN to be applied to land based radar, given the numbers required. Also you can provide it with more power.
Next in line will airborne, so the current version of India AWACS is probably GaAs based.

Further version might be GaN. We have to also consider the time required to qualify the TRM.

I am talking of the HEMTs at W/mm (power density). You are taking that as overall W achieved by the module, there is a difference.

So don't take 10w/mm as = to the 10W module achieved by a TRM which has entirely different subcomponents. The 10W/mm modules can operate at 5W/mm @ 28V. However, typically the larger value is mentioned (all-up performance), so the video above could be referring to the earlier components.

Also size matters. The Large Peak power wattage TRM systems mentioned (on the website) are the large modules for ground based radar using different types of components, base technologies, amplifiers etc. Some use GaAS, others use Si-based LDMOS tech. etc.

The compact TRM modules for X-Band are currently at 10W using GaAs modules, BEL/DRDO have them packaged in planks (4/6/8) depending on application. These are being used across Uttam, QRSAM, Atulya, BEL AESA BFSR and likely some strategic programs.

I remember the DRDO Chief's interview (forgot when it was made though) and given the rapid pace at which these advancements are being made, it could very well be he was referring to the lower power density HEMTs which resulted in a lower peak power TR module.

Ingenious design. A C band TRM with GaN Transmitter and GaAs Receiver from BEL! Neat, get the power efficiency for transmitter, but keep the cost down with the receiver.

Alpha, GaN 110W S band 7 TRM Plank. This solves the comment made by DRDO chief on waiting for S Band 110W. Wonder if this is going in to India AWACS.

[Karan M]

The first set are for QRSAM radars ( https://encrypted-tbn0.gstatic.com/imag ... IuJvb9S8wA), and Uttam. Second set, likely for AWACS India.

Alpha uses off the shelf GaN from global market, not Indian. BEL lady at the stall want too keen on answering questions about the X Band module. Atleast she object to taking these pictures!

Could you figure out whether it was for the regular programs in Arudhra etc or the AWACs.

[Karan M]

Note 8*65W peak in earlier TRM set. Now it's 7*110W, around a 50 perc increase in performance with one less TRM module.

No idea why the bel lady was acting that way. Wanted to ask us why we were so interested in the X-band systems. Guess, we should be thankful they're prudent?

And yeah they're CABS (and LCA) partners. The lady at Alpha was very enthu to talk to us. Several modules are being flight tested and she was greatly upbeat. Don't really wanna talk about ew stuff.

LUH clears 6-km altitude flight

(Unedited release)

The Light Utility Helicopter (LUH) has achieved an important milestone of flying at 6 km altitude here in Bengaluru, recently. The chopper was flown by Chief Test Pilot Wg Cdr Unni K Pillai (Retd) and Test Pilot, Wg Cdr Anil Bhambhani (Retd).

The flight was carried out under the envelope expansion tests and flying at 6 km altitude is a critical requirement towards the certification of LUH. The helicopter exhibited satisfactory performance and handling qualities. With the completion of this milestone, LUH can now undertake high altitude cold weather trials planned in January 2019.

The LUH is a 3-ton class new generation helicopter designed and developed by Rotary Wing Research and Design Center (RWR&DC) of HAL to replace the ageing Cheetah and Chetak helicopters used by Indian Armed Forces. First flight of LUH PT-1 was carried on September 6, 2016 and the second Prototype flew on May 22, 2017. HAL has in principal order for 187 LUH that includes 126 for Indian Army and 61 for IAF

Premier Explosives gets Israeli order for Rocket Motors.

Premier Explosives has received an order from an Israeli company for design, development, fabrication and assembly of rocket motors. The order value is $41,000 (about ₹30 lakh). The order has to be executed in six months. This is a trial order having potential for regular commercial supplies in due course of time, the company said in a statement to the exchanges. Shareholders of Premier Explosives will closely monitor the execution of the order and further order flows.

India's first private UAV factory comes up in Hyderabad.

India' first private sector unit for manufacturing unmanned aerial vehicles (UAVs) opened at Adani Aerospace Park here on Friday.

Built by the Adani Group and Israel-based Elbit Systems, the 50,000 square feet facility will develop Hermes 900 medium altitude long-endurance UAVs for the Indian and global markets.

The unit will begin with the manufacture of complete carbon composite aerostructures for Hermes 900, followed by Hermes 480, catering to global markets. It will further be ramped up for assembly and integration of complete UAVs.

The plant has been built at Adani Aerospace Park, the first defence and aerospace complex of Adani Group, at Hardware Park on the outskirts of Hyderabad.

The facility also houses advanced composites and high precision machining capabilities.

The plant was inaugurated by Telangana's Home Minister Mohammad Mahmood Ali in the presence of Pranav Adani, Adani Enterprise Ltd, Karan Adani, CEO, Adani Ports and Special Economic Zones, Bezhalel Machlis, President and Chief Executive Officer, Elbit Systems and Ashish Rajvanshi, Head Adani Defence and Aerospace.

[Vips]

To boost defence business, Adani to arm itself with Alpha Design.

The Adani Group plans to bolster its defence business with the purchase of a Bengaluru-based company that has a strong order book and partnerships with key manufacturers in Russia and Israel that are India’s top suppliers of weapons. This will be the group’s biggest acquisition in the sector.

Sources told ET that the Adani Group is set to pick up a significant stake in Alpha Design Technologies Pvt, with an initial investment of more than Rs 400 crore that will be scaled up over the coming months. The company has interests in defence and space, and works on products ranging from drones to helicopters and simulators. It’s a major supplier for the indigenous Light Combat Aircraft (LCA) programme as well.

Three persons confirmed the acquisition, which they said is likely to coincide with the unveiling on Friday of Adani Elbit Defence Systems’ facility in Hyderabad that will make Hermes 900 drones, initially for the export market, in collaboration with Israel’s Elbit Systems.

The acquisition is significant as it will give Adanis exposure to the export market as well as technical expertise to handle large military programmes under the Centre’s strategic partnerships scheme. ET has learnt that it is among bidders for the first programme to manufacture naval utility helicopters under the scheme. Teams from the navy are said to have inspected its facilities.

Entry Into The Big League
Adani Group and Alpha Design did not respond to queries. The acquisition will take Adani Defence and Aerospace into the big league alongside groups such as Tata, Mahindra, Reliance Defence and Larsen & Toubro that are vying for mega Make in India projects under the strategic partnerships scheme. Four projects have been initially identified under the programme — a new fighter jet, naval helicopters, a new diesel electric submarine and a future main battle tank.

As reported by ET, the Bengaluru-based firm recently pitched for an ongoing Rs 2,100-crore contract to upgrade a fleet of KA 28 antisubmarine warfare helicopters, proposing to the Navy that it can carry out the work in partnership with the Adani Group.

Yes Alpha Designs is one of the important suppliers to the LCA program. I am not sure but either the front or the rear fuslage is being supplied by them (with Dynamatics suppling the other remaining fuselage part and L&T supplying the wings).

Slowly and surely a nascent PVT sector MIC is emerging in India with players who have deep pockets:
Tata Systems
Bharat Forge
Mahindra
Adani
Reliance
L&T
Godrej Aerospace

[Karan M]

Still mostly limited to higher level assembly and design and development though is a plus.
The heavy lifting in foundry work continues to occur at GAETEC and SSPL.

Based on my googling skills and free time on hand, I have found out that, there is a GaN(using Indian MMIC) based C band(2-6Ghz) 4 antenna, land based radar in the works/already designed.

Adani group on shopping spree for defence.

Close on the heels of acquiring the Bengaluru headquartered defence firm Alpha Design Technologies for Rs. 400 crore and unveiling its own facility to make unmanned aerial vehicles (UAVs) at Hyderabad, the Adani group will continue its buyout spree in the defence sector across the globe, a top official said.

Speaking to journalists in Hyderabad at the UAV manufacturing facility on Friday, Adani group head (defence & aerospace), Ashish Rajvanshi said the group had in the last two years completed due diligence of some 300 micro, small and medium enterprises (MSMEs) in the defence sector. He said Adani group will buy some of these companies to help build up in-house capabilities.

“We (have) identified where the most unique capabilities lie, where they have been doing something which is not commoditised but which is something more future looking. For example, the software defined radios which is being talked about by the Indian Army is something which is being done by Alpha today,” said Rajvanshi.

“So, based on due diligence, we have identified Indian jewels which have now become part of the portfolio. And where we see a gap in our capabilities, tier-I and tier-II, we will continue with the strategy (of acquisitions). So, it will be a mix of organic and inorganic (growth),” he said.
Adani now has a portfolio of companies – Alpha Design, Comprotech, Autotech, and joint ventures with Elbit, Saab, Rave Gears and Rosoboronexport. “I can very proudly say, no other company can actually show this ecosystem to now transition to the platforms,” said Rajvanshi.

Adani group holds 51% in the joint venture manufacturing facility of UAVs at Hyderabad, where the Israeli defence giant Elbit Systems owns minority stake of 49%. The 50,000 square feet facility over 20 acres campus of Adani group will be the first facility outside Israel to make the Hermes 900 medium altitude long endurance (MALE) UAV, followed by Hermes 450.

In the first phase, the Hyderabad facility will make complete carbon composite aero structures and ramp up assembly and integration of complete UAVs. The joint venture will first cater to global needs and then look at making UAVs for domestic needs whenever it receives orders from the Indian Army.

Rajvanshi said Adani group was also looking to ramp up capacities of India’s first UAVs manufacturing facility, requiring additional investments. The JV facility will produce four units of UAVs next year and grade up to make 18 by 2020.

Further, Rajvanshi said Adani’s aerospace park in Hyderabad would also house a 50,000 square feet unit to manufacture high-end helicopter gears in joint venture with the US giant Rave Gears sometime by September next year.

Thanks for the links.

Interesting info from the presentations:
Plans to weaponize ALH, not rudra, but i believe the base ALH. May be something similar to what is done on Mi17

Future programs on Exo-skeleton, UAV for transport to mountainous region., laser weaponry, supersonic targets, multi-static radar etc.

Navy saying C/D search radar under "fight" has been indigenized, may be referring to RAWL-03.

DRDO under tech development fund will pay for Artillery PGK and a 500W Microwave SSPA. Also from IA, Mandarin to English & viceversa translation.

There is also a program for "re-inforced shell" for ATAGS.

[ramana]

Thanks to know about PGK funding. It was in limbo earlier.

Chinese language processing using AI is quite needed.

It is been called "Course correction kit". It is a IA project, one of the 4 projects under Technology development fund to be sanctioned soon.

DRDO Tech Focus Jan-Feb 2019

Radome Hood for Agni Missile System

The communication coach of Agni missile system consists of various types of communication equipment and satellite tracking antennae.This coach is a wagon similar to the wagons manufactured by Indian Railways with some modifications on the base platform. Canopy of the coach is designed such that it provides radar transparency to all installed communication systems. The composite radome hood was realized in four segments designed as per radio transmissibility requirement of the antennae. All segments are provided with water tight joints. Doors are provided at the end to facilitate maintenance of equipment placed inside.
