Bellatrix tests India’s 1st high-performance green propulsion system for satellites.

In a significant milestone, space transportation company Bellatrix Aerospace has successfully tested India’s first high-performance green propulsion system for satellites, a greener alternative to conventional hydrazine-based satellite propulsion systems. The Bengaluru firm developed a “proprietary high performance green monopropellant” with guidance from Charlie Oommen, professor, department of aerospace engineering at IISc. The test comes at a time various governments are considering banning hydrazine due to its toxic impact.

The proprietary green monopropellant possesses higher density than hydrazine, which means that more volume of propellant can be stored in containers of the same volume. Another advantage is the elimination of line heaters to prevent freezing of propellant. Elaborating on the test done in a vacuum environment, Saagar Malaichamy, co-founder and senior scientist at the firm’s mono propellant systems division, said “These tests validate functioning of many critical areas such as high temperature metallurgy, catalysis and energetic materials. We’ve performed multiple consecutive tests and the results are fairly consistent.

We are currently working towards optimising parameters to meet stringent requirements for acceptance in spaceflight.”

Saagar added that the product under testing is a 1N thruster suitable for use in micro/small satellites weighing between 50kg to 1,000kg and supports agile manoeuvres in space. “We’re also developing larger thrusters that could propel heavy satellites,” he said. The major combustion byproducts of the new Bellatrix thruster are water vapour based, making it green and environment friendly and its unique properties make it suitable for deep space missions with long coasting requirements.

Pointing out that Hydrazine requires strict safety standards for storage, transport and use of space propellants, the firm said that “while all rocket fuels can be dangerous to handle without proper safety precautions, our proprietary green propellant has significantly reduced toxicity levels compared to hydrazine, making it easier and safer to store and handle”.

Bellatrix CEO and CTO Rohan M Ganapathy, said: “Chemical propulsion uses completely different technology compared to electric propulsion. Development of this is a key indicator of our capabilities as a full suite solution provider with expertise both in electric and green chemical propulsion.”

T series definitely have thier weakness but I would wait regarding Russian losses, I remember Kosovo in 1999. NATO claimed to have smashed the Serbian Army and Airforce with fantastic claims , at the end of the war Serbian military with Entire Europe and USA against it was largely intact. I suspect the claims are similarly being exaggerated.

Don't need to demoralize IA tank forces based on propaganda, not to say T series have weaknesses and Arjun is clearly a better tank. But notice in soft mud which lasts till end of April USA is not sending Abrams, if this war goes till June, USA will gift Abrams along with Western heavies inspite of lesser pSI pressure are much vulnerable in softer ground.

The issue with Russian tanks is primarily on account of artificial size restrictions placed on the tanks. Due to lack of suitable rail beds. Or tank transporter.

Once you add the small size with lack of stabilised modern thermal optics and stabilised tank guns. You have a tank force with weaknesses that cannot be easily overcome.

Couple that with poor employment tactics and lack of organic infantry support and recce. You have a recipe for disaster.

It's not just in this war. This has be the case right since the 82 clashes between Israel and Syria. Every subsequent conflict Russian armour had performed in pretty much the same way.

The red army was well aware of the issues. They were also working on solutions for the weaknesses. The collapse of the USSR put paid to such ambitioo.

Armata is the latest in a long line of efforts from Russians over the last several decades.

The real question is how much money they have to really build sufficient numbers of the required vehicles.

The funny thing is that one of the justification for T90 purchase was the Shathora system on the tank.

But the Indian T 90 purchase left out the Shathora in order to save costs.

Having said that I distinctly remember a tender for the installation of APS on the T90 less than one year ago.

https://www.armyrecognition.com/defense ... a_mbt.html

It speaks of about 3000 vehicles being fitted with the system. So at least the Indian army is cognizant of the threat modern ATGM are presenting to the APCs

Soviet tank philosophy was on numbers not survivability, the magazine position is just one example. Mostly use and discard. Armata design is radically different.

The need for numbers of cheaper and easier to produce equipment is one aspect of the situation. If you look at the barrel life in terms of EFC. Then t72 barrels are under 400 shots. Whereas a L44 the basic western 120 mm tank gun barrel has a life of almost 1500 EFC.

A smaller vehicle because of smaller quantities of materials used will also be cheaper. Therefore for the material cost of 2 M1A1 at 60 tons a piece. Should allow for the production of 3 T72s. In terms of materials used.

NOTE:- i am not talking about the cost power pack and tank thermal sights, tank guns etc.

The other one is the artificial size limitations placed on Russian tanks by Nikita Kruschev. IIRC, it was he who had directed that all USSR tanks have to be under 37 tons.

If you see the Russian design is such a context. Then the placement of autoloader and smaller size starts making sense.

But all this also means that the crews cannot spend time on the training ground as much as the western crews can. Because the western tank is built much more rugged as compared to a USSR tank.

Only towards the end of the USSR did they start changing their approach to tank design. But haven't been able to put a successful design in service.

The Russian tank designs were predicated on an operational philosophy that came out of their experiences in WW2. Volume / Cheap / Easy of use and maintenance (by a conscript army).

Survivability was not an absolute requisite. The Russian army was always designed around mass and a volume of casualties was and has been an operational tenet. Western armies and also the Indian army puts greater value on its men and women - JMT

The same philosophy was also carried into their AK design.

]
in layman terms a much more powerful warhead in the same volume ., keep in mind this is HMX not any vanilla explosive. , side effects include a bigger "kill" radius and destructive power.

That is correct.

But the leathal modern battlefield has upended such a consideration. A 20 to 100 K ATGM can kill a several million dollars tank. The economic ratio is completely in favour of a light force equipped with good ATGM.

In order to function and survive on such a battlefield, armies need to have high quality tanks equipped with thermal sights, stabilised guns, modern armour, extremely close cooperation with infantry, artillery and airborne assets.

Absent such technology and cooperation, tanks are dead on the battlefield.

The good news is that Indian army has initiated the procurement process for active protection systems and integration of new thermal sights with the T 90.

The bigger question (for me, at least), is the effect that unmanned combat platforms will have on warfighting as a whole. My suspicion is that with increased use of armed-drones, UCAVs, UGVs, etc., the conception of victory through attrition goes out the window, because in a matched war, neither side will lose significant number of soldiers, so it'll come down to which side can maintain the tempo of war, i.e. economic considerations, production rates, attrition reserves enough to destroy the enemy formations to allow manned formations to capture territory through battle of maneuvers. But failing that, I worry we'll see the type of warfare that's happening in Ukraine, where one needs to destroy the enemy's will to fight by destroying their infrastructure that supports the war, as well as impose pain on the civilian populations to force a capitulation. It almost feels like a return to the old medieval siege tactics of starving out the population or threatening to kill them all unless they surrender.

Question is, does that make future wars more or less brutal?

Prasad, in case of a conflict between well matched adversaries. Victory will belong to the the side with integrated and well trained electronic and information warfare capacity.

The side capable of disrupting enemies C2 will win.

Does it make a future war more brutal. No, because war is already the most brutal of human endeavour.

One of the truisms of war has been that, if you can be seen, you will be hit, if you can be hit, you will be killed.

The integration of drones as sensors and tanks and arty as shooters compress the time frame of target engagement. Making the battlefield much more leathal than before.

Sort of like what machine guns and massed artillery did in the times past to massed infantry charges.

Indian government clashes with foreign defense sector over offset demands
:
:
:
The government has imposed penalties on several original equipment manufacturers from 2013 to 2021 for defaulting on their offset obligations, potentially deterring foreign defense companies from seeking business in the country. Those penalized OEMs include:

Lockheed Martin (a U.S.-based company) during work related to C-130J Hercules aircraft.

Textron (U.S.) for a Sensor Fuzed Weapon contract.

Safran (France) during a Mirage aircraft upgrade project and the acquisition of Rafael aircraft.

Dassault Aviation (France) during a Mirage upgrade project.

Thales (France) during a Mirage upgrade project and rocket-related efforts with Hindustan Aeronautics Limited.

European consortium MBDA for an effort involving MICA missiles for the Mirage-2000H and during the Rafael acquisition.

Rosoboronexport (Russia) for contracts related to Kamov Ka-28 helicopter upgrades, MiG-29 fighter jet upgrades and Mi-17 helicopters.

Fincantieri (Italy) for work on a fleet tanker.

Pilatus Aircraft (Switzerland) during efforts related to the PC-7 MkII basic trainer aircraft.

Israel Aerospace Industries for contracts involving Harop and Heron drones.

Indian Defence Ministry officials and analysts said at least a dozen more offset contracts could be penalized in the near future.

What's the bloody point. When you are buying from abroad. You are at the mercy of the seller to fulfill the terms of sale.

If they don't fulfill the terms. What you are gonna do?

What is the value of the fine. It cannot be punitive. Or the seller will just leave you alone and you are left holding an expensive piece of kit without any support and spares.

If it's not punitive, then the vendors will just laugh it off and get back to fleecing India.

another option is to move a significant portion , maybe 20-30 percent of payment to an escrow account valid till the date of purposed date for fulfillment of terms of agreement; any break in agreement would enable the buyer to reclaim the amount. The amounts previously made are peanuts and hence never taken seriously.

That list looks like a comprehensive list of all vendors !

Indian Army tanks to be equipped with advanced smoke grenades
Sandip Dighe / Apr 23, 2022, 03:32 IST



https://timesofindia.indiatimes.com/cit ... 016354.cms
Pune: The Indian Army’s battle tanks and Infantry Fighting Vehicles (BMPs) will soon be equipped with advanced 81mm smoke grenades to ‘confuse’ the enemy forces on the battlefield.

The grenade emits a thick layer of smoke to obscure the enemy’s tank for at least for 40 seconds — sufficient time to get into a strategic position to counter adversaries.

It has been developed by the city-based High Energy Materials Research Laboratory (HEMRL) of the Defence Research and Development Organisation (DRDO).
