What is funny in this pic ?

Velocity trimming module + payload adaptor

Why ?

That's the civilian equivalent of a MIRV bus

And people wonder if India has MIRV enabled ballistic missiles or not .

What is funny porkistan is mentioned in Wikipedia MIRV topic to possess MIRV

Seriously ?

Madrasa educated porkies can't even design a guidence system for their missiles on their own and they have MIRV capability ? lolzzz

It's dimensions are very similar to the RS 28 sarmat ICBM.

 

[porky_kicker]

This makes it even more funny

Liquid propellent based velocity trimming module ( military name RCS - reaction control system ) as terminal stage for precise injection requirements.

12 nos thrusters producing 50N each

Pitch roll and yaw control during coasting phase

Roll control during 2nd and 3rd stage

One should not have doubts regarding how the Indian 1st generation MIRV bus might look like with certain necessary modifications ofcourse

Watch this video , very interesting

Especially from 15 m till end ( 16.20 )

What led to creation of JNU and why it is pro porkistan.

Fucking commies they played a very long hand, even before 1947 and surprise surprise JNU was a result of it.

Those in power must know this yet why JNU is not being shutdown beats me

This channel is good and contains good info , subscribe if possible , every help counts.

We must support pro Hindu channels

Aluminium cenosphere syntactic foam which can be placed as a layer in buildings, bridges and flyovers to protect them from collapsing or suffering severe damage during a bomb blast.

During an explosion the voids inside the material would absorb the blast and the material would shrink in volume. This material can also be used in tunnels, ammunition depots, armoured vehicles and tanks.

If a tank with a layer of this material moves over a mine, 80 per cent of the blast impact will be taken by the material.

1) The material is being tested in a machine which has a gas gun. “Striker bars” hit the material at different levels, which are correlated to different intensities of blasts.

2) Different models of the material.

3) The machine can conduct experiments at 120 psi. At this level in a real life blast, a building will be obliterated.

Two UUVs being developed at IIT Delhi

1. Hydrocopter
2. Nemo

The Hydrocopter will be used for underwater surveys of the hull of a ship to ascertain damage to it.

The Nemo will be used for finding sea mines.

If you look at the video you will notice the low depression angle of the ATAGS gun barrel relative to the carriage. I believe it can go a few degrees lower.

This allows for use of ATAGS in a direct fire mode.

Coupled with the 25 litre chamber it provides the ATAGS the capability to blow up well protected tanks and armoured vehicles in a anti tank role with direct fire.

So that leaves the vulnerability to molten copper warheads from ATGMs.

 

[porky_kicker]

Newer version of battlefield surveillance radar - short range (BFSR-SR)

I think it is AESA based

 

[porky_kicker]

So that leaves the vulnerability to molten copper warheads from ATGMs.

Sandwiched armour plates made of different materials like various ceramics , silicon carbide boron carbide aluminium titanium alloys etc will break up the molten jet

This technology already exists

NEW DELHI : India on Wednesday conducted a successful first test flight of the indigenously developed Hypersonic Technology Demonstrator Vehicle (HSTDV) from a base off the Odisha coast. The only other countries that possess this technology are the US, Russia and China.

The HSTDV is an unmanned scramjet (allowing supersonic combustion) demonstration vehicle that can cruise up to a speed of mach 6 (or six times the speed of sound) and rise up to an altitude of 32. km in 20 seconds.

It has a range of uses, including missiles of the future, and energy-efficient, low cost and reusable satellite-launch vehicle.

Why the army's changed mindset on indigenous technology is a relief | India Today Insight

Vice-Chief of Army Staff Gen. M.M. Naravane said that the army would accept indigenous technology even if they didn't meet the 'best' parameters. Improvements, he said, could be made later. In any other country, army officials endorsing home-grown technology would not have been a non-sequitur. But in the Indian context, these major endorsements signal a welcome shift in the thought process.

Indian industry officials say the army has been the slowest of the three services to embrace indigenous technology. This could also be explained by the fact that it is the least technology-intensive of the three services. The army is manpower intensive. It does not operate hundreds of fighter aircraft over vast airspaces nor does it have platforms as technologically intensive as an aircraft carrier or a nuclear-powered submarine. Army testing procedures are rigorous and trials of critically required equipment like bulletproof jackets often go on for years without achieving results.

The navy has worked closely with the DRDO to perfect indigenous sonars. The army can only claim a handful of successful collaborations such as the Dhanush which fielded an indigenous 155 mm howitzer from blueprints supplied by Bofors in the 1980s. Three critical systems-the Tactical Communications System (TCS), Battlefield Management Systems (BMS) and the Future Infantry Combat Vehicle (FICV) have been on for over a decade without a prototype in sight.

In recent years, the army has embarked on what could only be called Quixotic pursuits. A bizarre contest to buy a multi-caliber rifle-a single rifle firing two different types of ammunition-was scrapped after seven long years. Last year, it shut down a BMS project that would seamlessly link all its fighting formations, citing high project costs.

Yet, nothing compares in the scale of neglect to the army's now-shelved Beta battle computer project. The Kargil War of 1999 exposed how little the infantryman's kit had changed since the 1971 war. Project Beta, flagged off in 2003, then, seemed astonishingly ahead of its time by army standards.

Among the early projects initiated by the Army Technology Board, the aim was for every soldier to field a hand-held computer. It was the army's leap into the digital battlefield of the future, bringing the Indian soldier on par with counterparts in the US and Israel who were racing to develop the same capability.

Project Beta's hand-held or body-worn PDA would enhance a soldier's situational awareness in the battlefield by answering three basic questions: where am I, where is the enemy, and where are my comrades?

The answers would blip on the screen of a hand-held device, rugged-proofed for military use. The device was meant to equip infantry companies (100 or more soldiers) engaged in counter-insurgency in Jammu and Kashmir.

The project combined the expertise of Bengaluru's IT industry with academia, defence scientists along with end-users. Bengaluru-based Encore software collaborated with the Indian Institute of Science (IISc) and the DRDO. The Indian Army's Directorate General of Information Systems worked as co-developers and end-users on the project. "It was a unique partnership and it would have been a fantastic base for us to build on for the army's future projects," says Colonel D.P.K. Pillay (retired) who coordinated Project Beta at Army HQ, New Delhi.

By 2005, the team had produced an integrated battlefield computer that would allow a soldier to pinpoint his exact location on a Geographical Information System (GIS) powered map, allow friendly troops to see his position on their screens and allow communication between them. The Situational Awareness and Tactical Handheld Interface (SATHI) packed a lot into an 875-gram rugged set that was smaller than a brick. The solar-powered PDA ran on a 128-bit encrypted system, a Linux programme and was capable of withstanding temperatures between -20 degrees C to + 70 C. It had a 5 km range and a GPS receiver-with a 24 hour battery life. It supported both voice and text for devices deployed in the mission area. Its software-controlled radio allowed regular updates of device positions, messages and map markings over the entire network, directly, or by relay. The password-protected device, its manufacturers say, could even act as a decoy if it fell into enemy hands. If unauthorised attempts were made to log in, the unit could actually reveal the position of the person attempting the break-in to friendly troops.

When the first 120 units were tested, it was a formidable game-changer. Infantry closing in on the enemy knew their location and those of friendly forces in real time. Troop movements could be monitored by commanders on a laptop several kilometres away. Each Sathi unit theoretically had unlimited range because each unit acted as a relay station, bouncing signals to the next unit and thus doing away with the need to erect signal relay stations to boost range. The system was successfully demonstrated to President A.P.J Abdul Kalam. The developers drew up plans for a series of devices using the same core and operating systems which could scale up the Sathi's capabilities and be used by decision-makers up the command chain.

In 2008, a proposal for a second batch of 1,300 Beta-2 devices came up before the Army Technology Board for funding approval. The project team wanted to test it across a wider area. That's when the army pulled the plug on the project. The decision took the project team by surprise. It was almost inexplicable, says one officer who worked on the project. "We don't need to reinvent the wheel," a three-star officer who headed the army's Information Systems (IS), reportedly told the project team when they protested. Project Beta was closed down. The Sathis already manufactured were consigned to the almirahs in the office of the D-G, IS. It was a move that would have delighted the dozens of foreign equipment manufacturers who are now offering their own solutions to the Indian Army.

Cut to 2019. The army still does not have a hand-held computer. Special forces operatives crawling up on the enemy at the Line of Control have no way of knowing where their comrades are at. Infantrymen engaged in combing operations operate just as they would do several years ago--through radio, mobile phone or hand signals. The Sathi project remains a wistful reminder of what might have been.

Could the project be revived? Quite easily, says Colonel K.P.M. Das (retired) who worked on the project and is now with Cisco Systems. "The technology has gone through four or five cycles since then, with the result that today's start point can be achieved in a matter of months. A Sathi for 2020 can do a hundred times more than what it did 15 years ago and a large number of military-grade systems can be fielded in a year." A resurrected Sathi could well be the biggest statement of the army's indigenisation intent.

Betichod Congis killed the project to delay modernisation and buy overrated systems from Italians.

 

[Aaj ka hero]

Betichod Congis killed the project to delay modernisation and buy overrated systems from Italians.

Did this happened? never knew systems we bought from Italians.
But anyway if someone point it they have the READYMADE answer "monetary restrictions",this way of doing things WILL NOT TAKE INDIA ANYWHERE.

I think it's the Army to blame, rather then politician.
