DRDO Sensor CNT (NOx Gas).

The accurate detection of NOx is an important issue, because nitrogen oxides are notonly environmental pollutants, but also harm to human health. An array composed of two carbon nanotubes (CNTs)-based ionization sensors with different separations is proposed for NO and NO2selective detection. The experimental results indicate that the CNTs-based ionization sensor has an intrinsic, monotonically decreasing response to NO or NO2.

Which type of engines is Bharat Forge developing?

Mini and micro jet engines for missiles and drones and at the same time they are designing a turboshaft engine of perhaps 1300 kw capacity.

Yes but there would be complications if all deployed within same geographical area . Interference in EM spectrum , complications with handover protocols , weapon release protocols etc

Not that it cannot be resolved but it would be time consuming and involve additional manpower and resources.

On paper QRSAM standalone can do the job of point area defence same as NASM , the role for which it is being bought .

On paper even Spyder system can do the same job.

What exactly are the advantages with NASM I don't know , actually capabilities of weapon systems are mostly classified , wheather it is a geopolitical buy or a need base purchase , that remains to be seen

Is this the 600-800mm one that was being developed or the older 530mm one?

Army looks at desi vendors for improved ammunition
TNN | Feb 5, 2020

The Army is looking at Indian vendors for development of prototypes of ammunition, which can penetrate a 530mm thick armour of enemy tanks from a 2km...
...“The present in-service ammunition has a DoP of 460mm. Therefore, there is a requirement to indigenously develop an improved APFSDS ammunition.”

 

[Shaitan]

Is this the 600-800mm one

I have never heard of this one.

 

[Bleh]

I have never heard of this one.

And this is the Mark2, with "more than 500mm penetration".

Now that private companies can soon produce DRDO tech free of royalty, Kalyani/Tata/L&T may hopefully cut OFB out of the equation.

Portable Acoustic Landmine Detector

Portable Acoustic Landmine Detector (PALD) can be operated by a single person to detect and discriminate artificial objects such as landmines buried in the ground. PALD exploits the acoustic resonance of buried objects and identifies the mine from the clutter with its unique acoustic signature.

Main uses and domain

Strategically important indigenous development which can be used in both wartime and humanitarian de-mining operations. The Acoustic Mine Detection System (AMDS) is unique in the sense that no commercial products are available in the world market for landmine detection using Acoustic technology.

Features and Technical Specifications

35 cm by 35 cm UDV array as scanning head

Scanning height upto 50 cm

Total Weight of Handheld unit(sensor) less than 4 Kg

Exciters fixed on mini trolley

Total power 250W to 400W

Audio and Visual alarm

It's a practise round... Might not penetrate as much as the real ones...

Of course --- Baap Ka langar hai free Ka money bhi :biggrin2:

Damn... I completely missed it. Thanks!

No, a practice-round will be much cheaper imitation with only similar ballistics.

Inductive Pellet injection technology demonstrated at Aditya U tokamak.

Disruption mitigation using pellet injection is an important technique being examined for ITER.

On the Aditya-U tokamak, a fully-electromagnetic IPI (Inductive Pellet Injection) system has been successfully integrated and commissioned. In the first experiments, a few hundred milligrams of powder has been injected at high velocity. The powder quenches the plasma in a few milliseconds through intense radiation.

This specialized field of research originated as a possible solution to the problem of depositing atoms of fuel deep within magnetically confined, hot plasmas for refueling of fusion power reactors. Using pellet injection systems, frozen macroscopic (millimeter‐size) pellets composed of the isotopes of hydrogen are formed, accelerated, and transported to the plasma for fueling.

The process and benefits of plasma fueling by this approach have been demonstrated conclusively on a number of toroidal magnetic confinement configurations; consequently, pellet injection is the leading technology for deep fueling of magnetically confined plasmas for controlled thermonuclear fusion research.

Hydrogen pellet injection devices operate at very low temperatures (≂10 K) at which solid hydrogen ice can be formed and sustained. Most injectors use conventional pneumatic (light gas gun) or centrifuge (mechanical) acceleration concepts to inject hydrogen or deuterium pellets at speeds of ≂1–2 km/s.

foreign lobby is the baap ..............
if this is the case for such a small system then imagine the lobbying in weapons .it reminds me of the arjun trials similar thing also happened with one foreign company participating in tender.

It happens everywhere in India. Remember Train 18, Sudhanshu Mani ji had told,that someone damaged the electrical parts of the train. Also, dalals were trying to import foreign trains.
