Chinese scientists are moving ahead with hypersonic precooled engine like SABRE which can have serious implications on future power balance in the region (read hypersonic bombers of chinese air force). So sad that our government agencies are completely ignoring this particular technology.

hmm, it is quite dangerous.

from that they can make ssto and space planes missiles. (8-9 th gen fighter ??)

but it will not last in space for long time bec it will be chemical powered.

and can be used in space travel.

We haven't started research yet?
On that area?

imo we are working on desi sr72 it will be ramjet+ chem/solid rocket.

and this saber tech is far superior to what we are working on.

bec ours will have 2 engines and theirs will have one engine but it can transition from one mode to another

Triveni signs a business agreement with GEAE Technology USA in its Defence business

Triveni Engineering & Industries Ltd. ('Triveni'), a market leader of engineered-to-order turbo high-speed gears & gearboxes, an indigenous approved supplier of engineered products & systems apart from approved supplier of indigenous marine gearboxes for the Indian Navy and Coast Guard shipbuilding projects, today announced signing of a 10-year business agreement with GEAE Technology USA to locally manufacture the LM2500 gas turbine base and enclosure.


Under the agreement, GEAE Technology USA has licensed Triveni to locally manufacture the LM2500 gas turbine's base frame, acoustic enclosure, and lubricating oil skid and supply other source-controlled accessories that go into the LM 2500 gas turbine enclosure assembly. The LM2500 is the chosen propulsion gas turbine by the Indian Navy for many of its surface combatant vessels. The LM2500 gas turbine, with power ranging from 25 MW to 35 MW, are best in class naval propulsion gas turbines and are in service with over 40 navies globally.

Yes..Exactly..But even SR72 is far more superior to us. It will be able to fly at around mach 18 and gather data at the same time. Can be used as an unmanned bomber as well..and most importantly it is small and compact. USA is also moving ahead with precooled engine tech...Search about HERMEUS, a startup from Georgia Tech University. I am lucky enough to have interacted with the team.

Preliminary studies are being conducted in IIT Kanpur, but that is only limited to that..Only a few CFD simulations...They don't have enough funds to make a proto and test.. Unless government agencies gets onboard, it will remain a simulation only

Drdo was working on hypersonic aircraft since 90s
Don't know what happened,feasibility studies were completed by 2012

India has started to put in place the building blocks for an operational BMD system which in its first phase will be providing ballistic missile defense cover to NCR and Mumbai besides keeping track and providing situational awareness of all ballistic missile launches from Pakistan.

Under the BMD program , we have already built and operationalised one VLLRTR and one variant of LRTR radars by 2020. These facilities are manned by joint NTRO and IAF personnel and officers. Besides these we also have LRTR radars and MFCR along the Eastern coast of India. These are manned by DRDO personnel and are utilised for the R&D of our fledgling BMD phase 1 and phase 2 program and also for tracking the flight path of various in service missiles and experimental vehicles test launched from Integrated Test Range and Wheeler island respectively .

A brand new radar station under the BMD program in addition to the above mentioned facilities is being constructed on the outskirts of Udaipur in Rajasthan . Earth works and construction of various facilities at this radar station started in early 2019 . When compared to the other radar stations meant for the BMD program, this one is ginormous and is on another level. When fully completed in the coming years this station will house four radars of various types. As of now , the facility is partially operational or will be operational in the coming months with one very long range LRTR radar and one variant of LRTR presumably the LRTR3 variant .

This deployment pattern is reminiscent to the Israeli EL/M-2090 Terra system which comprises of the UHF band Ultra and the smaller S band Spectra radar which works in conjunction to each other with the Terra radar performing the function of ultra long range early warning and tracking of incoming ballistic missiles of NLOS-BSM, TBM, MRBM,IRBM and ICBM classes while the smaller Spectra radar provides higher resolution track data that can be used for fire control and providing mid course updates to the PDV and AAD interceptors.

Thank you Modi for providing the required impetus to deploy and make the BMD system system instead of treating the whole project as some of exotic grad science project like the previous govts.

This is more of an extension rather then deployment of First phase. Swordfish is getting replaced by LRTR in a different location.

What is the detection range of VR-LRTR??

For fighter size target flying low, its 600 km. Take it around 400 km in logical sense.
For high flying missile size target, 1500 to 2000 km depending on area of operation.

our mod and its babus will realise this when chinese hypersonic jets would have started flying above us .

result of lack of space startups.

One of our bottlenecks currently is in CMCs of Zirconium Diboride matrix reinforced by Silicon Carbide fiber. If we want to build a hypersonic bomber or even a long range HGV, we need this tech.

No one is ignoring the tech. But to design a precooled engine, we have to design a reliable engine first. Precooled engine development is nothing new and people have tried to design it earlier too with a sucessful design on using liquid notrogen. But it has its own drawbacks in matter of weight and size. Our approach is to use hydrogen as a coolant and fuel. But their are some design limitation to it too and study is on way.

 

[BrigadierRPS]

Nothing happened after that. Simulations only.

Simulations were carried out in IIT Kanpur keeping pressurized liquid hydrogen in mind.
