Shaurya evolution is perhaps pralay ..

The dimensions of Pralay was a takeaway that its indeed a derivative of Shaurya, and further development of it only means its made for Anti-Shipping. The only visible difference is it being 1m dwarfer. Pralay can easily cover 1300-1500km with 500-300kg payload.

Anybody have re-entry video of Prithvi Warhead? Could this be submunition warhead for anti-tank/ anti-personnel purposes?

some old info regarding work on smart munitions by drdo

DRDO has previously successfully demonstrated several technologies for the development of Smart Munitions to defeat enemy armour from its vulnerable top.

These technologies include:
1.Explosively Formed Projectile (EFP)—A copper liner serving as antenna for the sensor in the search mode and forming a single projectile in the attack mode.

2.Detonator Arming Safety Device for activating EFP

3.Efficient capsule ejection system

4.Highly compact MMW sensor

5.Rotatoil parachute for stabilising the sub-munition and scanning the ground target

The technology has been validated for 120 mm Mortar.

The system can be suitably developed for launching from various types of platforms.

It can also be adopted for platforms like High Calibre Howitzer/Field Guns, multibarrel rocket systems, Prithvi missile and aircraft carrier bombs.

now these technologies have matured/progressed to the point that drdo has quite a few smart munitions under development/testing.

IIT-Kanpur students design unmanned helicopter prototype, bag award in international competition
Aug 20, 2017, 11:17PM IST TNN

[ Abhinav Malhotra ]

KANPUR: A team of postgraduate students of Aerospace department of IIT-Kanpur have been successful in developing a prototype of an 'unmanned helicopter' named "Vibhram" which can fly continuously for 24 hours while carrying a payload of 80 kg. The novel design of this helicopter helped the students bag the third place in the graduate category of 34th Annual Student Design Competition organized by the American Helicopter Society (AHS). IIT-Kanpur students beat teams from University of Liverpool, a second team from Georgia Tech, Nanjing University of Aeronautics and Astronautics (China) and some other prestigious institutions of world fame.

Meet Karthik S. (Team leader, MTech), Rahul Ramanujam (Team technical leader, PhD), Ramdas (PhD), Diksha Aggarwal (MTech), Sakshi Gupta (MTech), Avinash Shet (MTech), Vishesh Kumar Singh (MTech), Naba Kishore Routray (MTech) who developed 'Vibhram' helicopter under the guidance of Assistant Professor Abhishek of Aerospace engineering department and Prof C. Venkatesan (Emeritus Fellow Professor in Aerospace Department.

Talking to TOI, Assistant Prof Abhishek said, "The design of Vibhram is very innovative. It has novel dissimilar coaxial rotor concept which was conceived for this competition by PhD student Rahul Ramanujam (a patent has already been filed on this concept). This rotor concept has been predicted to be more efficient than any existing helicopter concept such as conventional (single main rotor and tail rotor) and regular coaxial helicopters by 15-30%. This revolutionary new design is expected to have a strong impact on the future of helicopter technology. A research paper on the design authored by Rahul would be presented in September at European Rotorcraft Forum in Milan, Italy."

He said that such a type of a helicopter design does not exist anywhere in the world and its prototype has been developed by the students in only six months starting in January this year. "We were required to submit a 100 page report, an executive summary of the project and a video of the operational helicopter which we had provided to AHS for taking part in the competition. The hardwork by the students bore fruits and they won the third prize", he added.

He further mentioned that this is for the first time in 34 years that a team from Asia has finished on the podium of this competition in the graduate category.

"The objective of this year's competition was to carry out conceptual system level design of an unmanned helicopter that can fly continuously for 24 hours while carrying a payload of 80 kg", he said.

The entire design work was carried out as part of AE 660: Preliminary Design of Helicopter course taught by Assistant Professor Abhishek in the previous semester. Professor C. Venkatesan gave his guidance to the team.

The professor said that he and his team of students are now working on scaling up the version of this helicopter.

L&T Dual Band Shipborne Tracking system

it is a high precision tracking system for Aerial Target tracking on board ships. This fully automatic system has dual-frequency dual-polarized S & Ka band antenna that detects the desired target flying in any direction in 3D space, gets locked-on to the target and keeps on tracking it as per the requirement.

While pointing towards the flying target, a 4-axes stabilized gimbal with antenna pedestal automatically compensates for the disturbances caused by ship dynamics up till sea-state-5 using intelligent algorithms. In addition, the system also tracks the target using thermal imagers.

This system has been developed indigenously and involved multiple engineering disciplines like antenna, RF, digital processing, servo & control and mechanical systems.

This system is one of its kind in the world which uses two widely separated frequency bands (S & Ka) for target tracking. The usage of very narrow beamwidth Ka-band system, for tracking high speed targets from shipborne platforms, is another unique feature of the system.

Impressive to have two different wavelength and frequency band, that too S and Ka in one single aperture. Do you have any link for tech specs of this set up. What is the size of the aperture or antenna? S band does need a huge antenna of say 25mtr or so. But the one in pic doesn't look that big.

artillery radio-jammers, the jammers operates in HF and VHF

these shells are fired into target areas to disrupt enemy radio communications

no dont have the links for tech specs of this set up.

i posted what is available in open domain .

u could try googling though , see if anything extra turns up.

Tried it. Nothing more is available in open domain. Nothing about the frequency jamming artillery shell too. But seems, Cold Start Doctrine is up and kicking......

this is a old pic of a unknown aerial bomb from drdo under going high speed sled test

note the embedded panel

no info exists on it, atleast i have not been able to find any info on the same

is it a conventional bomb ?

Congratulation. You might have found the first prototype of Mirage payload. The side panel is most probably for on board sensors and electronic components.
