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.

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

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

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?
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.

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

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?
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.
REGARDS....

This year's Trophy for 2010 for the Best Systems Laboratory of DRDO has been awarded to Research Centre Imarat (Programme A D ) , Hyderabad in recognition of the outstanding achievements of the Laboratory in developing a Ballistic Missile Defence System.
Technology Leadership Award for 2010 have been awarded to following scientists:
Dr V Bhujanga Rao, Distinguished S c i e n t i s t and Chief C o n t r o l l e r R&D, DRDO HQrs and Director, Naval Science and Technological Laboratory (NSTL), Vishakhapatnam, for outstanding contributions in the design, development, and induction of indigenous underwater weapons, naval stealth products, underwater mines, fire control systems, and autonomous underwater vehicles.
Shri S S u n d a r e s h , D i s t i n g u i s h e d Scientist and Chief Controller R&D, DRDO HQrs for his pioneering the development of complex, multi-disciplinary, t e c h n o l o g y -i n t e n s i v e Integrated Fire Control System (IFCS) for MBT Arjun through successful system integration, weapon system trials, and user acceptance.
Dr G Malakondaiah , D i s t i n g u i s h e d Scientist and Director, Defence Me t a l l u r g i c a l R e s e a r c h L a b o r a t o r y ( D M R L ) , H y d e r a b a d , for his valuable contributions in the development of speciality low-alloy steel DMR-1700 as a costeffective replacement of maraging steels. AB class naval steels were indigenised under the leadership of Dr G Malakondaiah and are being used in the construction of first indigenously built aircraft carrier at the Cochin Shipyard.

New AESA radar MPR prototype ready.....
DRDO's Solid State Physics Laboratory (SSPL) working on Graphene
Orders worth over Rs 25000 crore for surface-to-air missile – Akash have been placed by the Services. These include 8 squadron for the Indian Air Force (IAF) and 2 regiments for the Army.
Successful flight tests of AAD Endo Atmospheric Interceptor for 2000 km class target were carried out. Each flight led to a direct target hit and disintegration of the target.
