Roadmap of High Energy Materials in India: DRDO vision.

1) Gun propulsion systems are being developed keeping in mind the requirements of high performance, IM compliance and temperature independent performance. Along with triple base propellants having impetus of 1020 J/g, high performance Gun propellants (HPGP) are in the advanced stages of development. High energy gun propellants with temperature independent performance is one of the promising futuristic products in the roadmap of gun propellants systems.

2) High Explosives having TNT equivalent of the order of 1.4 are in regular production in India and less sensitive, EIDS as well as IM compliant high explosive compositions are in the advanced stages of development.


3) IM compliant warheads, thermobaric explosives and high density pressed charges (p >1.84 g/cc) are on the roadmap of High Explosives
Technology development.

4) Notable work has been done in the field of protection systems for tanks and aircrafts. ERA Mk-I and Mk￾II as well as NGERA are the capable technologies developed and technology for APS for threat from all ATGM, HEAT, KE is under development..

5) Monospectral and multispectral flares are successfully developed and pyrophoric /covert IR decoy flare technology is being developed with promising advancement.

6) At HEMRL, rocket propellant development is focused on high performance Extruded Double Base propellants, Nitramine Composite Propellants, Active binder based advanced propellants and solid fuel rich propellants.

7) The energetic ingredients like HMX, CL-20, Ammonium dinitramide (ADN), TKX-50, aluminum hydride (AIH3), Boron Aluminum ligature are being developed and used for advanced propellant development.

8) The active binder based propellants having 12-14 s higher specific impulse as compared to conventional composite propellant have been successfully developed in a large scale. Research and development of propellants having 20-25 s higher Isp as compared to conventional CP is targeted to be completed by 2030

9) Fuel rich propellants based on Boron Aluminum ligature with the specific impulse of ~ 1000 s is in advanced stages of development and further improvement aiming specific impulse of
~ 1200 s is also targeted till 2030.

10) Not only the energetic ingredients but the advanced propellant processing technologies like continuous mixing, segmented mandrel, combustible mandrel technology are also being explored at HEMRL. Collapsible mandrel technology for monolithic casting up to 50 T class motor having complicated geometry has successfully been established.

11) HTPB made by anionic polymerization having controlled microstructure and narrow molecular wt distribution has better potential of improving performance of conventional composite propellants.

12) As one of the remedial solutions for improving processibility and sensitivity of advanced energetic propellants, technology for Making spherical nitramines like RDX and
HMX is also under development at HEMRL.

Significant Achievements of drdo AR&DB structures panel.
Some of the significant achievements of the ACECOST (1999-2018) programme formulated by the Structures Panel are as follows:

Development of co-curing technology for aircraft structures like wing. The knowledge generated here and from the LCA programme helped NAL in designing the horizontal and vertical tail of the SARAS (14 seater indigenous aircraft developed by NAL).

Generation of valuable design data for co-cured composite joints of different configuration and varied loading conditions (pull, shear, combined pull-shear, hygrothermal, impact loads). Extensive testing of co-cured joints was carried out under various conditions. This helped in design validation of wing test box of LCA and SARAS horizontal and vertical tails.

Design and development of a CNC-based stitching machine that was used for stitching both prepregs and perform materials.

Development of NDE techniques such as infrared (IR) Thermography and laser based ultrasonic methods for in-process and post-fabrication inspection of composite laminates.

Development of quick-repair schemes for composite structural damages.

Development of a portable cure controller for carrying out in-situ repair of damages in MIG aircraft. This instrument is being used by IAF at 11BRD Nasik, HAL-Bangalore and Jet Airways-Bangalore to carry out in-situ repair of aircraft parts.

Development of a novel, cost-effective manufacturing process called the VERITy (Vacuum Enhanced Resin Infusion Technology). CSIR-NAL developed this technology as an alternate process to prepreg￾autoclave molding which is at least 20% cheaper than current prepreg based composite technology.

Development of Structural Health Monitoring technology. The foundation laid in SHM in ACECOST program propelled CSIR-NAL to participate in other DRDO programmes. CSIR-NAL successfully demonstrated SHM technology on both the NISHANT UAV (in collaboration with ADE) and the HANSA aircraft of NAL. This had put India in the top 9% of the world of SHM researchers in actual conduct of
flight trials.

Post-buckling response based design methodology was established. This approach can result in 5-10% weight savings compared to present design philosophy. Beneficiaries: ADA, ADE, AR&DC-HAL etc.

Optimal design methodology for aero-elastic design of helicopter blades were developed. Beneficiaries: HAL-RWRDC

Demonstrated damage tolerance design philosophy for composite aircraft structures. Beneficiaries:
ADA, ADE, HAL.

Impact detection in composite aircraft structures using fiber optics and Lamb wave based techniques were developed. Beneficiaries: ADE, ADA, HAL, R&DE (Engrs).

Processing technology for Carbon-PPS Thermoplastic composites developed. Beneficiaries: ADA,
HAL, ADE, R&DE (Engrs), GTRE.

Modeling of Liquid Composite Molding process developed which can be used for process optimization. Beneficiaries: ADE, R&DE (Engrs)

A Design and Analysis tools for Rotor Blades of Helicopters. Beneficiaries: HAL (LCH)

Damage Tolerance and Fatigue testing for composite structures Based on Research work damage tolerance studies on Rudder and Fin of LCA-Tejas Programme were carried out.

Developed thermoplastic composite technology. Thermoplastic composite can be recycled and is a major green initiative. Parts like wing spars and skin-stringer panels have been developed under this program. It is proposed to use this technology for next generation of aircraft like AMCA.

Some of the significant achievements of the Structures Panel projects from 2018-2023 are as follows:

Design Analysis of Adhesively Bonded Composite Patch Repair of Cracked Aluminum Aircraft Panels
was carried out. Domain Lab/Probable Beneficiary: ADE

Here is the weight optimised version.

That's why saab agreed for license production.

"it was 28 wheels trailer by TATA advance system"
The above TEL which is shown in Republic day parade never went into production (mostly)

Agni 5 mk1 , agni 5 mk 2 & agni 6 use 56 tyre TEL

I saw 56 tyre TEL of IA (sat pic)

Picking American Stryker Over India-Made WhAP Is A Setback To Atmanirbharta In Defence

The India-made wheeled armoured vehicle had the infantry combat vehicle variant; however, the US-made Stryker was picked.

swarajyamag.com

Great attack by Swarajya, this is clear cut favor deal, I don't know what Americans are giving in return.
Man, ask for additional Chinook, apache.
Ask for V-22 osprey, if Americans so desire a deal.

Maybe threatened to stop supply of GE F414 engines for Tejas if we did not purchase that failed tin can ?

Typical commie article by commie rag The Week ! They can't even make a heavy diesel engine (a proven technology and not rocket science) for
Arjun tanks and they will make an impact on the global auto market ! What a joke.

Nag, the anti-tank missile, will go in for repeat summer trials this year

What the hell ! Nag is still not inducted ?? Someone pls update the real status of this never ending MNREGA project .
