Why Gas generator ? You mean to say it is not used for propulsion ? Then why need this big a gas generator (going by Arun-saar's drawings) ? Attitude control or extending aerospike wont need that high pressures. Preventing water entry for underwater operations is about the only other thing I can think of.
Lakshmic,

I think Ramana was talking about the design of the SUM, not its purpose. It is to be used for Propulsion only. The design, if it is a solid fuel type, is very likely to have a high Loading Fraction and but not necessarily a low Loading Density. In addition, it is bound to have significant chamber pressures, allowing for a short, sweet burn.
On the other hand, the Hindu business line has consistently said that Agni III itself is composite bodied.. whereas the TSS artcles indirectly hint at composite bodied being a future aim rather than current reality...
IMO it is difficult to see the Agni-III first step to have anything other than a composite casing if the vehicle is to in fact lift off the ground. Perhaps the future work is to make the whole missile as composite body. Certainly a worthwhile goal to try and achieve.

On a sidenote, Arun_s: The Chamber Pressure stated on the BR Agni page are the time averaged pressures or initial or final pressures from your calculations?

Thanks in advance.

Lakshmic: In the above article the key operative sentence w.r.t. the "Mohini Nrytum" is
DRDO has developed a state-of-the-art case-bonded HTPB-based composite propellant with low burn rate of 4.3 mm/s at 50 KSC.[/u]at 50 KSC.
That slow burning motor is key to Agni-3's stated & unstated performance.

Looks like the Chankiyan Yindu's are truly unconstrained and free. They publish their secrets in publication for the incredulous world to think is that is really true/possible for the nation so poor, whose father roamed around the world half naked. :twisted:

Agni-5: India plans 5000 km range Agni-5 missile

May 10, 2008
By Syed Akbar
Hyderabad, May 9: India has already attained the capability of developing missiles, which could hit targets beyond 5000 km range, according to Avinash Chander, programme director of Agni missile system.
Avinash Chander, who is also the director of Advanced Systems Laboratory that developed the Agni components, said his lab would now take up the design of the new missile system. "We have the capability of making 5000 km range missiles, but we have to make the designs first. The designing part will be over in two year's time," he said.
Interacting with a select group of reporters here on Friday after the successful test-fire of Agni-3 missile earlier this week, Avinash Chander said the next programme would be Agni-5. There's no need for Agni-4 as it's just an upgradation of the existing Agni-3. "We are looking forward to developing Agni-5 missiles with multiple warheads.
The present missile system carries only one warhead. The advanced stage of Agni-5 will be capable of carrying three warheads that could hit the given target or the set of different targets with precision,"
he pointed out.
The Agni-3 missile has filled the vital gaps in India's defence capability while Agni-5 will take it a step further. "We are on par with the European nations and China when it comes to possession of missile system capability. Only the USA is ahead of us," he claimed.
The development of Agni-5 will put India on an advantageous position in the region as it could hit any target within the geopolitical system. Only the USA, Russia, France and China have missiles beyond the 3,000 km range. India has
joined the select club with the successful test-firing of Agni-3, which has a range of about 3,500 km. "The Agni-5 technology will be totally indigenous," Avinash Chander said.
Referring to Agni-3, he said it has a state-of-the-art inertial guidance, highly accurate sensors with high immunity from jamming. The ASL is also working on new
warhead technologies that could be used for Agni-3 and Agni-5. The warheads will be capable of hitting the given targets piercing through the anti-ballistic missile defence system of the enemy. They are capable of fooling the radar system.
There will be decoy warheads which will be fired along with the genuine ones. The idea is to divert the attention of the enemy's defence system. The enemy will lose its anti-ballistic missiles firing at the decoy warheads while the real warheads will hit the targets, destroying the enemy's capability. The warheads will also pass through the atmosphere dodging the enemy's missiles.

interceptor missiles

Post by Prabu »

To

Arun_s & Ramana Garu,

NAMSAKARAM.

What WILL HAPPEN if our BRAHMOS is fielded aginst our own AGNI 3 ? which system will beat which one ? And for the (probable) failing one do we have alternates ? How about our adversaries developing / (or already developed ?) Anti missiles for our AGNI 3 ?

Request to throw some light.

Thanks,

Also implies that the ~150kt boosted fission warhead will be the standard one, does'nt it ? At least that one should be mass produced.

That package/config is only for insect eating unconvinced tubelights up northeast of Arunachal Predesh.

Yes no SUM. Thus this panda express medicine is only for neighbouring reptile.

Hi burn rate is desirable for main motors. For long range missiles OTOH it is desirable to have slow burning motor operating at lower pressure / thinner case material. That allow precision of a surgeons scalp in inserting the payload on desired trajectory. Small thermal signature is also important in space.
----------------------
Edited later. To change second sentence to:
For long range missiles OTOH it is desirable to have the last stage as a slow burning motor operating at lower pressure / thinner case material.

Agni IV ready to take off

BALASORE: If everything goes according to defence scientists’ plans, nuke-capable and most powerful longest range missile Agni-IV will in India’s arsenal soon.

This has been envisaged as after the successful test-firing of 3000-km range ballistic missile Agni-III earlier this month, defence scientists have already started planning for the maiden test of Agni-IV.

“This 5,000-km range missile has already been developed. The missile will be tested from the Wheeler Island only after scientists get the government nod, which could be anytime this year,â€

India’s most sophisticated and indigenously developed Agni was first tested on May 22, 1989 from the Integrated (then Interim) Test Range (ITR) here.

The Agni-IV missile, which will surpass all the previous three versions of the missile, will be surface-based, solid and liquid-propellant ballistic missile and equipped with inertial guidance systems with an improved optical or radar terminal phase co-relation system.

Thats BS & DDM. No liquid propellant - Only solid.

First of all BRAHMOS is a surface/air/sea to surface ramjet powered missile. I think you mean PAD. Well PAD as of know is designed to intercept Gauri class IRBMs of say 1500km range. AIII will be much more agile and they say has designed in features of anti- ATBM measures. Only things that can take on AIII right now are the US NMD type ABMs.

Okay, so 5000-Km Agni IV has already been developed and can be tested this year while 5000 Km Agni V will take 5 years to develop. Beautilful. :rotfl:
