Read this after post #363 on page no 19 of the "Indian Army Artillery Systems" thread. You will realise how significant this is :

Novel approach to make Solid Rocket Propellant gets patent for UoH faculty

13 May 2020 Last Updated at 5:33 pm | Source: IANS

Hyderabad, May 13 (IANS) The Advanced Centre of Research in High Energy Materials (ACRHEM) -- a DRDO Centre of Excellence in University of Hyderabad -- has been granted a patent for a process that finds major application in aerospace engineering and other areas.

The process patented under the title ''Hydroxyl Terminated Polybutadiene (HTPB) based Polyurethanes'' is the invention of Prof Tushar Jana and his associates, Dr. Bikash Kumar Sikdar and Moumita Dhara. Prof Jana belongs to the School of Chemistry, UoH, as well as adjunct faculty in ACRHEM.

Hydroxyl-terminated polybutadiene (HTPB) is a viscous liquid that has several uses. Its most important application is in solid rocket propellant (SRP) where it binds the oxidizing agent and other ingredients into a solid but elastic mass.

The present invention describes a process for the tethering of energetic molecules or nitrogen-rich molecules at the terminal end of HTPB, which has resulted in an energetic HTPB binder, and also imparted superior properties than the native HTPB.

HTPB is an inert prepolymer that contributes nearly 10-15% mass of the propellant compositions; replacing the inert mass by energetic molecules and retaining inherent properties is a very crucial step to obtain an energetic binder.

Speaking to IANS, Prof. Jana said, "We have shown a new process, what we call a synthetic method in which we showed that we do not actually change any of the properties of the HTBP. As a result we will not disturb any of the properties of the propellant which we make. We are able to produce a more energetic fluid which actually gives more energy to the system."

Indian Space Research Organization (ISRO), DRDO and various space and defence agencies across the globe employ HTPB-based binder to manufacture composite propellant systems. The inventors believe that the binder material described in this invention has very strong potential to replace the traditionally used HTPB binder in the manufacturing of solid rocket propellant.

The invention also reveals a synthetic methodology for the preparation of polyurethane (PU) with significantly high tensile properties from HTPB and various isocyanates. This will be of great help in manufacturing flexible polyurethane (PU) rubber with specific physical properties for various high-end applications such as aerospace engineering, surface coatings and surface sealants, high-performance adhesives, synthetic fibers and carpet underlay, and hard-plastic parts.


As is typical of the Indian media, quite a bit of the reporting here is inaccurate. In case you are looking for the original journal they published, here is a glimpse :

India-UK to work jointly in jet engine development
Post-Brexit, India and the UK are exploring several options for jointly collaborating in defence projects and will soon finalise a government to government format for future defence deals. According to the UK Minister for Defence Procurement James Heappey, “Soon there will be a government to government agreement related to collaboration in developing a jet engine.” Without elaborating further the visiting minister indicated that the announcement will come soon.

Since India prefers a government to government route, the two sides are keen to have the framework for future defence deals soon as the jet engine agreement is expected soon.

The visiting minister also offered joint technology development for the sixth generation fighter aircraft and the same could be used in India’s Advanced Medium Combat Aircraft (AMCA).

Both India and the UK in 2017 had agreed to cooperate in the development of advanced defence projects including the gas turbine engine and air defence missile systems. Also there is a collaborative project between engine maker Rolls Royce and Defence Research and Development Organisation on jet engine technology.

UK-INDIA sign MoU to strengthen defence collaboration
On the sidelines of the DefExpo, to forge closer defence ties between the two countries, the UK India Business Council (UKIBC) and the Society of Indian Defence Manufacturers (SIDM) signed a Memorandum of Understanding (MoU).

The MoU was signed in the presence of the UK Minister for Defence Procurement James Heappey MP, Director of the UK Department for International Trade’s Defence and Security Organisation (DSO) Mark Goldsack.

The MoU is expected to help both sides in building partnerships and capabilities in the Aerospace and Defence sector. Also support and build on the huge opportunities for collaboration that exist between the defence industries of the UK and India. Under the MoU, the collaboration will not only advance India’s defence acquisition process but also foster long-term technology and hardware transfers.

Rolls Royce in India

The British company Rolls-Royce has a strong legacy of 87 years of partnering India with strategic collaborations for technology transfer in engine programmes as well as to ‘Make in India’.

According to Kishore Jayaraman, President, Rolls-Royce India and South Asia, “Today, as India accelerates its rise as an economic and geopolitical force in the global arena, it has the width and weight to invest in co-creation and co-development programmes in strategic areas. The future will be about collaborations with willing global players to ‘Create in India’, where the country co-owns the Intellectual Property (IP).”

At the Expo the company is displaying future-ready defence and naval combat powering capabilities including the “mighty” MT30, the world’s most power-dense marine gas turbine in service today. There are solutions for both land and naval defence, and this includes the Integrated Bridge System that is an advanced marine automation system for efficient ship operation from our MTU brand.

Rolls-Royce’s MTU engines currently propel and power many Indian Coast Guard and Indian Navy vessels, as well as India’s indigenously built Arjun Main Battle Tanks.

There are more than 750 Rolls-Royce engines of 10 engine types which are powering aircraft of the Indian Armed Forces and the support is given by a dedicated Defence Service Delivery Centre, Bengaluru.

The company has a skilled talent pool of engineers at their Engineering Centres in Bengaluru and Pune, which provide engineering capability for global projects spanning research and development as well as new product design and development.

“We are also keen to support India’s goals of indigenisation and self-reliance through technology partnerships and co-development initiatives. Also to have co-creation programmes this will help in co-development of technologies in areas of strategic importance. This would help to bolster commercialisation of production in India and strengthen the ecosystem to become a global supplier and exporter of defence technologies,” said, Jayaraman.

MT30 – Powering the Future

Proven at sea, MT30 can deliver its full power of up to 40MW (depending on application) in ambient temperatures up to 38°C, without any power degradation through life of ship. And this enables the ship to operate anywhere without loss of performance or power.

EM 50-2 – Advanced Marine Automation System

The EM 50-2 is a modern integrated bridge responsible for providing access to all information that is crucial to safe and efficient ship operation, that collates information previously scattered over diverse displays at a standardized display using a single graphic interface which enables faster overview using an ultra-modern visuals concept.

The DRDO designed Silver-Zinc battery used in LCA Tejas comprises 15 cells each producing 1.8 V. Aircrafts use batteries with high surge output to run systems before the Auxiliary Power Unit and/or the engine is turned on.

The Boeing P-8Is are going to use the Ni-Cd battery designed and developed by DRDO and industry. this will replace the imported batteries already in use in those aircrafts. The battery has a 5 year or 700 discharge cycle service life.

Both are extremely necessary.

The Su-30s are needed to complete squadrons.

The Mig-29s are to retain a significant psychological edge over the PAF F-16s. Since the F-16s can't beat the Mig-29UPG in both BVR and WVR. So adding greater numbers of our own in relation to PAF's growth in their F-16 fleet is necessary to retain the edge we have over their fleet.

12 Su30MKI is justified as completing the squadrons.

But Mig29 purchase should be delayed. We should spend our resources according to a priority list.

And just for the sake of discussion, assume that we have a priority list of acquisitions for IAF.

In that hypothetical list, according to me, the Tejas MK1A order should be finalized before anything else.

Having done that, Refuellers and AWACS. Even if leasing some Il76s from Russian stocks and refitting them with refueling capability and 2 more A50 Phalcon. These things also certainly are much more important at the moment right ?

Having procured and signed for these things, if our purse still allows, then surely additional Mig29s

The deal is around 2 billion dollars peanuts basically. And mig 29 isn't as bad an aircraft as it's claimed to be. We need awacs and refuellers but we should have enough aircrafts so that we can maintain a numerical edge. Our awacs are qualitative superior to Pakistani awacs..

Surely quality is there in AWACS. The problem is that 3 + 2 aircrafts are not enough to cover the pakistan front and Eastern Air command. Forget covering both, even in just 1 theater , they are not enough to provide continued surveillance. The 27th Feb incident has 2 lessons for us, 1st was the change in RoE. And 2nd was AWACS.

And as of today more AWACS are actually topmost priority. Even before MK1A deal actually.

The problem is there but axing the su30/mig deal is stupid the planes are cheap and we need them immediately, for some reason IAF focuses on fighters more than on support elements. Otherwise we wouldn't have the problem in the first place even Singapore has more awacs and refuellers than us. We could easily buy more phalcons and drdo awacs but we aren't and I don't know who to blame because even IAF isn't taking the problem seriously.

That's an old post.
Now that we already ordered, there is no use in reviewing it.

Am interested in what upgrade are we going to make..

And update work is going to be done in both Russia (21) & India (66)

I Think this is going to be fast to get capability.

The LCA deal will likely be cleared before the Mig-29.

As for refuellers, although those are delayed, I don't think they are as important as our fighter jets. So the Mig-29 takes precedence here. The Americans and French are capable of supplying tankers if necessary, during wartime. It's obvious you need fighters first, and then refuellers.

As for AWACS, while the 2 additional Phalcons are delayed for any number of reasons, the govt has given clearence for AWACS-India, so it's not such a big problem since time will solve that issue. Both received DAC clearance before the Mig-29s anyway and both only require CCS clearance. So the govt does have their priorities right. Plus we have P-8Is.
