ADM WARHEAD FOR PINAKA CLEARS TRIAL
BANG ON: NAG HITS BULL’S EYE IN FINAL DEVELOPMENTAL TRIALS
Re: India's R&D in Defence DRDO, PSUs and Private Sector
Have we finally run out of excuses for inducting the Nag?
The first missile was fired in the “worst time window” on 28 September. The missile hit the target precisely near turret location. A bull’s eye hit was scored as confirmed by officials of the Indian Army present at the spot. The second flight test was carried out with an objective of proving 4 km range capability of Infrared Imaging (IIR) Seeker. TTS was once again used as target and thermal mapping from a T-72 tank to TTS was carried out. The missile hit the target bang on – this time on the engine location of the target.
Operational target scenario presents mixed contrast of the target with respect to surrounding sand, shrubs and background clutter. IIR Seeker is capable of handling complex scenarios.
Independent Stabilized Sighting Systems for the Gunner and the Commander, Fire Control System, Launcher Platform, Drive System and Missile Operating Stations are the main subsystems of NAMICA. The Commander’s Panoramic Sight (CPS) is used by the Crew Commander for target surveillance and exploitation of Hunter-Killer capability. The Gunner Sight is used for target acquisition and missile firing. Six ready-to-fire ‘NAG’ Missiles can be mounted on the Launcher Platform. Amphibious trials & mobility trials have been successful

DRDO seems to be worried that there will be more excuses, seen from the multiple times they emphasize (in that article) that army personnel were present and witnessed the bulls eye hit.Indranil wrote:Have we finally run out of excuses for inducting the Nag?

<OT>I have few noob questions -
1> Are there any basic differences in IIR seeker used in ATGM and an AAM?
2> Can the later one, due to its range and agility, be used in ATGM roles? I guess only major difference is a specialized warhead (fragmented Vs shaped charge).
Re: India's R&D in Defence DRDO, PSUs and Private Sector
On the issue of the NAG discussion, does the Army plan to adopt a similar testing regime to the Hellfire anti-tank missile that it is acquiring with the AH-64 Apache purchase? I think not. Phoren is always better, in fact so amazing that it does need testing at all.

A team of researchers has discovered semi-conductivity in bismuth at around -273 C°
Researchers at the Tata Institute of Fundamental Research (TIFR), Mumbai, have made a landmark discovery that challenges the conventional understanding of superconductivity.
A team, lead by Dr. S. Ramakrishnan of the Department of Condensed Matter Physics and Material Sciences at TIFR, has discovered bismuth semi-metal in bulk form becoming a superconductor when the temperature is lowered to 530 microKelvin (about -273 degree C), which is three orders of magnitude higher than the theoretical prediction. The results were published in the journal Science .
“The Bardeen-Cooper-Schrieffer (BCS) theory [which explains superconductivity in most low Tc superconductors] cannot explain the superconductivity seen in bismuth,” said Dr. Ramakrishnan, the corresponding author of the paper. “The discovery demands a new theory and a new mechanism to understand superconductivity in bismuth. This discovery provides an alternative path for discovering new superconducting materials which are very different from the conventional superconductors.”
Superconductors are materials that conduct electricity with no resistance whatsoever. To become superconductors, the element should have mobile electrons, and these electrons should come together to form pairs, known as Cooper pairs. Unlike other elements in the periodic table, bismuth has unusual phenomenon — while metallic superconductors have one mobile electron per atom, bismuth has only one mobile electron per 100,000 atoms. Since carrier density is so small, people did not believe that bismuth will superconduct.
Also, bismuth’s electronic energy (Fermi energy) is comparable to the lattice (phonon) energy. “So the conventional BCS theory and its extensions which assume that Fermi energy is two to three orders of magnitude higher than phonon energy is not valid in bismuth. We know that if we prove superconductivity in bismuth, it will be from a different mechanism,” Dr. Ramakrishnan said.
“Superconductivity in bismuth is puzzling. Even at 10 milliKelvin, people did not find superconductivity in bismuth. So they gave up nearly 20 years back,” said Om Prakash Shukla from TIFR and the first author of the paper.

Based on this DRDO report, can we expect mass production of the Nag and Helina? Looks like the 4 Km local IIR seeker works just fine:
Anti-tank Nag Missile System demonstrated Successful:
Nag, the third generation, lock-on-before-launch (LOBL), fire-and-forget, anti-tank guided missile, indigenously developed by the Defence Research and Development Laboratory, Hyderabad, scored a “bull’s eye” successfully hitting targets up to 4 km away in the final developmental trials. The Thermal Target System (TTS) was used as target for the missile. TTS simulated a target similar to an operational T-72 tank. For the flight test, a T-72 tank was moved for one hour and positioned at a range of 3.2 km. Thermal mapping from tank to TTS was carried out for generating thermal signature. NAG has ‘Top attack’ and ‘Front Attack’ capabilities. It is capable of defeating the heaviest type of armour including ‘reactive’ and ‘composite’ armour of the futuristic main battle tanks. Critical technologies indigenously developed for NAG Missile System include a high resolution IIR Seeker developed by RCI, Hyderabad. The performance of the Seeker is well established in guided flight tests of NAG. The second trial validated the enhanced 4-km range capability of IIR seeker, which guides the missile to the target after its launch. NAG, which has been developed to support both mechanised infantry and airborne forces of the Indian Army, is designed to destroy modern main battle tanks and other heavily armoured targets. It can be launched from both land and air-based platforms. Technologies for ‘Tandem Warhead’, ‘Control System’ and ‘Solid Propulsion System’ for NAG have been successfully developed by ARDE, Pune, RCI and ASL, Hyderabad. NAG Missile Carrier (NAMICA) is BMP2 based Infantry Combat Vehicle (ICV) suitably configured for firing ‘NAG’ Missile. NAMICA is an advanced system developed by DRDO. The development trials were conducted with an objective of proving higher range capability of high resolution IIR seeker. NAG Weapon System is ready for induction into Indian Army.

Very impressive rocket motor.Lot of coded words in the description. So they reduced the weigh of insulation by 80 kg in Mark III version. In essence the isulation is made like a sock and the composite wound over it. Its then cured together and hydro tested for pressure. Composite case allows higher pressure in addition to weigh savings.
Energy is proportional to burn area and pressure.
HtBP allows soft propellant which precludes cracks.
Wonder how many pour for the 12 tonne motor. One or two? Or may be 3.
