Sonars and related technologies developed by DRDO

[Omega007]

So as I told mr pakistani natioalist,our indigenous active protection system was ready for testing,but he did not believe.
REGARDS....

I heard a news from a unreliable source that Navy is manufacturing a another nuclear submarine of another class with double the size of Arihant.
Is it true?

MATERIALS TECHNOLOGIES




Details about DRDO developed technologies on several advanced materials and technolgies in the areas of metallurgy, ceramics, polymers, elstomers and composites. New ship building steels, titanium sponge, high super alloys, electro ceramics, advanced composites etc. Ca,ouflage materials, acoustic and radar stealth materials, NBC protection materials, protection materials for extreme weather, anticororrosion materials etc.

DRDO labs: DMRL, DMSRDE, DLJ, NMRL.

1) Vacuum Investment Casting of Advanced Nickel base Superalloys: DMRL has successfully developed technolgy for making advanced nickel based super-alloys for Kaveri Engine . Technology transferred to HAL Koraput.

2) Supercast 247A alloy for Turbine blades and vanes

3) Advanced high temparature Titanium alloy Titan-29A

4) Ultrahigh strength, high fracture toughness low alloy steel

5) Ceramic cores for Kaveri engine aerofoil castings

6) Production of titanium sponge

7) Isothermal forging of Ti alloy discs for high pressure compressor of aeroengine

8) Naval steels: AB class of steels ABA (DMR-249A) and AB2 (BMR-249B) for aircraft carrier. Now navy has decided to use these steels for all future vessels. DRDO now working on naval steels with higher yield strength (>780 MPa) to meet the futuristic requirements of Indian navy.

9) Materials and technologies for armored vehicles: SPAE M1 as substitute of Russian 42 CM armour in T-72. Kanchan composite armour for MBT Arjun. Recently DRDO developed 130 mm think amour steel to replace Russian 53 C grade armour steel for T-90 tanks. A variety of armour materials like ceramics, titanium, high hardness armour steel and composite armour for use on ICV Abhay have been developed. Protection to helicopters both during assault or combining operations as well as during transport mode is essential for safety of the crew. DRDO developed light weight composite armor for Mi-17-IV helicopters as a replacement for existing imported heavy steels armour so as to improve its net payload capacity at high altitudes like Ladakh. Significant weight reduction (35%) and higher protection against defined targets have been achieved.

10) Phase Change materials: Speial low-fusion metal alloys (metal eutectic) of Bi, Pb, Sn, Cd, In have been developed with tunable melting points in the temperature range 45-80 degree C.

11) Magnetic nanomaterials.

12) Magnetically controlled fluid.

13) Plastic scintillator material for radiation monitoring

14) Graphene

15) Carbo-Graphite material seals

16) NBC shielding pads for combat vehicles

17) Individual protective equipment for chemical warfare

18) Carbon nanotubes and related materials

19) Materials for high temperature applications

20) Nanofluids

21) Carbon Silicon carbide composites for jet vaes, TVC, throat inserts, hot gas valves etc.

22) Cyanate ester-based composites for high temperature Radome applications

23) Al-Zn-Mg alloys for underwater weapons

24) Acoustic sensors

25) Plastic bonded explosives

26) Al alloys for torpedo

27) Acoustically transparent rubber compound

28) Materials for sonar systems

29) Encapsulating materials

30) Vibration Isolation module jelly for towed sonar arrays

31) Micro-cellular polymers

32) Nanomaterials and polymer nanocomposites

33) Polymer nanoclay composites

34) Acoustic baffles

35) Underwater acoustic signal absorbing materials for stealth ship and submarine

36) Wedge shaped linings

37) Magnetorheological fluid and smart devices

38) Ceramic materials and composites : Boron carbon ceramics, piezocomposite materials,ceramic components for solid oxide fuel cell, PZT microtubes,

39) Polymer materials

40) OLED

41) Semisolid slurry for new rheocasting technology

42) Novel electroless anti-foiling device

43) High performance exterior paints for naval applications

44) Fire redundant paints

45) High build Chlorinated rubber-tar anti-corrosive paint

and many more...

It should be, "HE DOES NOT WANT TO BELIEVE". lol

Is it true?

As of news GoI approved 5 nuclear submarines. The first one on sea trial ie INS Arihant while Second one at final stage of construction and the Third one's hull is taking shape. The later two should be larger to accommodate Agni-6.

 

[Ghoster]

Yes, its the missile hump behind the sail to carry K-15 or K-4.

The hump looks very small.

The hump looks very small.

Its not small.

What!Did I hear right!DRDO has developed the OLED!You mean the Organic Light Emitting Diod!I can't believe it!I mean that's just AWESOME!!!!!!!!

Cmon dude..... Development of OLED is not a big thing. DRDO sources its OLED components mainly from SAMTEL and other cos.Its not worth the time and money to develope such technologies, where DRDO should be investing its time in developing critical tech.

OLED concept is sooo simple. Get a rippen cuccumber and insert two wire terminals init. Now power the terminal. For best effect, turn-off lights in your room.

Not only DRDO , but also IIT-Kanpur. "Centre for Display Technologies" is set up inside the IIT Kanpur Campus, a Joint venture by SAMTEL, IIT-Kanpur and Department of Science and Technology

You are partially correct regarding transfer non-critical R&D to private and institutes but OLED is vast they might be working on better system. Though Samtel makes OLEDs but do not know if it is the result of Samtel-IITK-ISRO JV.

Thank you for photos. Are they can be used for AIP?

 

[Omega007]

I think in this power output level they can't be used in submarine AIP systems.The germans used 9 HDW proton exchange membrane fuelcells with 30-40 kw each in the 1st type 212 ssk and later models use three 120 kw cells.So the energy output has to be drasticaly increased,which will be done by 2013.
