SRM can be throttled , special SRM with thrust modulation exists. DRDO working on same

In my twitter timeline have posted on it

There are a lot of articles and research work available on internet for example

On-Off mechanism
Hybrid system https://core.ac.uk/download/pdf/237587414.pdf

It looks like this stuff is still in the experimental stage though.

The only known experiment done took the heat generated all the way to 3200deg C, that's way too much for something like a CM.

The throttling ability seems to be role-specific.
The new design adds a significant feature. By varying the speed at which the fuel rod is forced into the engine, the thrust can be varied as in a liquid-fuelled rocket.

Being able to throttle a rocket means its thrust can be reduced when reaching "max Q" - the spell of maximum aerodynamic pressure when rising through the atmosphere - and throttled back up again as the air thins.


It speaks of throttling when navigating the different layers of the atmosphere, a problem CMs don't face.

Also, the throttling doesn't seem as dynamic as it's the case with liquid fuel. It appears the throttling happens in phases, as each section of fuel disappears. So it's for a properly planned flight path, where you know exactly where you're launching from, and you know exactly where you need to go, and your comm and support infrastructure is built for that purpose. Otoh, weapons need to be fire and forget. They need to be launched from anywhere at any target that can move, plus can deploy countermeasures. So a CM like Brahmos constantly changes speed, direction and alitude while it travels towards its target.

Also, an autophage eats itself and practically disappears, whereas the next phase of CM capability will require us to bring back most of the missile for reuse. So a Brahmos that flies up to its target, fires off the warhead, and whatever's left returns, thereby functioning like a UCAV. Something that requires a hybrid engine setup that combines a turbojet with a scramjet, so the turbojet can bring the missile home. I don't know how well solid rocket will work with such a setup, probably won't. So I don't see CMs giving up the liquid fuel advantage anytime soon.

For BMs and space rockets, definitely. It's interesting to have the bulk of the body composed of only fuel.

And what do you think about that On-off mechanism, that I’ve mentioned on the previous post. Is it workable using igniters similar to space rockets ?

I think I’ve heard some DRDO project (Sudarshan ?) goes to target, drops warhead and returns back like Sudarshan Chakra of Lord Krishna.

No clue.

It was APJ Kalam's wish to see a Brahmos that is reusable. Basically a UCAV with one warhead.

Synopsis
"India and Philippines are in an advanced stage of negotiations over the sale of BrahMos supersonic cruise missile. Export order likely to be placed soon," government sources told ANI. "DRDO and BrahMos Aerospace together have been pushing hard for exports of this missile to friendly foreign countries: for the last few months," sources said.


In what could be a major success for the Narendra Modi government's defence export push, India is expected to soon get export order from Philippines for BrahMos supersonic cruise missiles.

"India and Philippines are in an advanced stage of negotiations over the sale of BrahMos supersonic cruise missile. Export order likely to be placed soon," government sources told ANI.

"DRDO and BrahMos Aerospace together have been pushing hard for exports of this missile to friendly foreign countries: for the last few months," sources said.

The Indian government's defence export push is coming from the DRDO stable as it bagged orders for a 'made-in-India' weapon locating radars from the Armenian government recently.

India is likely to bag more orders for the missile system from friendly countries as it is negotiating at an advanced stage with some other nations too.

The missile is also getting more capable due to added range and other modern technologies getting incorporated into it.

Senior scientist Atul Dinkar Rane has been appointed as the new head of the BrahMos Aerospace Limited and he has worked with the firm since its inception days.

Our first major export.


In a huge boost to India’s mission to turn a defence exporter after decades of being seen as an importer, the Centre has struck reportedly struck a deal with The Philippines to sell the indigenous BrahMos missile system for a whopping $55.5 million dollars.

With this, The Philippines has become India’s first foreign customer for the cruise missile system, a joint venture between India and Russia.

According to Hindustan Times, The Philippines has reportedly allocated 2.8 billion pesos ($55.5 million) for its initial funding to procure the state-of-the-art weapon system.

“India and Philippines are in an advanced stage of negotiations over the sale of BrahMos supersonic cruise missile. Export order likely to be placed soon. The Defence Research Development Organisation and BrahMos Aerospace Limited together have been pushing hard for exports of this missile to friendly foreign countries: for the last few months,” government sources told news agency ANI earlier this week.

The ‘Made in India’ weapon is likely to draw more orders from ‘friendly countries’ as negotiations are at an advanced stage with several other nations.

As other deals come through, the BrahMos supersonic cruise missile is also getting a facelift with added range and other modern technologies.

Senior scientist Atul Dinkar Rane, who has been appointed as the new head of BrahMos Aerospace Limited, has worked with the organisation since its days of inception.

The medium-range BrahMos is one of the fastest supersonic cruise missile systems in the world.

With a speed of Mach 3.5, the missile has a maximum range of 650 kms.

soon the Next-gen RF imaging seeker is going to be integrated with Brahmos NG, Maybe this is already used in AGNI-P :rolleyes:

DRDO successfully test fires sea-to-sea variant of BrahMos supersonic cruise missile​

The Defence Research and Development Organisation (DRDO) has successfully test-fired an advanced sea-to-sea variant of the BrahMos supersonic cruise missile. The missile, launched from the Navy’s recently commissioned stealth guided missile destroyer INS Visakhapatnam on January 11, apparently hit the designated target ship with pinpoint precision.

According to officials familiar with the launch, the sea-to-sea variant of BrahMos was test fired to its maximum range while verifying the accuracy of the ship’s combat system and armament complex. According to a Navy spokesperson, the launch of the missile from a floating platform validates a new capability and enhances the capabilities of the Navy. Defence Minister Rajnath Singh, while congratulating the scientists working on the BrahMos project, said that the successful launch was a reconfirmation of the robustness of the "Indian Navy’s mission readiness".

A joint collaboration between India and Russia, BrahMos is capable of being launched from land, sea, sub-sea and air against surface- and sea-based targets. The missile flies at a speed of 2.8 Mach or almost three times the speed of sound and can carry both conventional and nuclear warheads of 300 kilogrammes. Although the supersonic cruise missile’s range had been capped at 298 km in tune with stipulations of the Missile Technology Control Regime (MTCR), the DRDO, following India’s entry into the MTCR club in June 2016, recently extended and successfully test fired the missile to around 450 km (to be further extended to 600 km).

Last December the air version of BrahMos was test fired from the Indian Air Force’s Sukhoi 30 MK-I aircraft. Several Asian countries have shown a keen interest in BrahMos.

Rajnath Singh's Vietnam visit may add momentum to Brahmos plan

Defence exports and joint collaboration including training and maintenance of defence equipment (both India and Vietnam use Soviet- and Russian-made defence equipment) could top the agenda of the three-day visit, ET has learnt. Vietnam is also interested in purchasing the Brahmos missile jointly produced by India and Russia.


Amid growing Chinese aggression in the ASEAN region, this is Singh's first trip to South East Asia since the pandemic.

Defence minister Rajnath Singh will likely visit Vietnam in the second week of January to celebrate the golden jubilee of the establishment of diplomatic ties between New Delhi and Ho Chi Minh City.

Vietnam is also interested in purchasing the Brahmos missile jointly produced by India and Russia.

Amid growing Chinese aggression in the ASEAN region, this is Singh's first trip to South East Asia since the pandemic.

Last year, Singh and his Vietnamese counterpart Sr Lt Gen Phan Van Giang held wide-ranging conversation on implementing the joint defence plan. During the virtual interaction, both ministers reviewed the progress on the current initiatives and expressed commitment to further enhance engagements between the defence forces of the two countries under the framework of India-Vietnam Comprehensive Strategic Partnership (2016) and under the guidance of the Joint Vision for Peace, Prosperity and People signed during the Virtual Summit between the prime ministers of the two countries in December 2020. Both the ministers acknowledged the significance of the Joint Vision Statement of 2015-20 in strengthening defence cooperation engagements between both the countries thus far.

The leaders had agreed to initiate measures to enhance cooperation in the defence industry and technology domain. In a series of tweets following the virtual meet, Singh had termed the relationship between India and Vietnam as "strong and effective". He had said: "India attaches great importance to its bilateral defence cooperation with Vietnam. Both India and Vietnam share a long-standing tradition of helping each other in difficult times. We have achieved substantial progress in defence industry cooperation in recent years."

India and Vietnam had upgraded their ties to the level of Comprehensive Strategic Partnership (CSP) in 2016 and President of Vietnam's National Assembly visited India in December to celebrate five years of CSP. India's $100 million defence Line of Credit to Vietnam has been utilised for naval equipment. India has been training Vietnamese military personnel and also helping them with maintenance of some defence products.
