DRDO, PSU and Private Defence Sector News

[Steven Rogers]

Which DRDO technical publication they are talking about?

And Indian Defence Review and Wikipedia? Another two fan boy site.

And you are quoting a publication of 2011, means written in a period of 2008 to 2010.

From 2008 to 2011, all trails of Shaurya were completed
http://www.thehindu.com/sci-tech/sc...-testfires-shourya-missile/article2482010.ece
In the last test, it went over 700kms with an altitude of just 40kms, that suggest flat trajectory which is only possible with a boost glide vehicle on a ballastic missile.

It's neither IDR OR wiki, even wiki gives references to deal with.

Then how did you quoted Scramjet as boost glide vehicle.

I said HSTDV as a boost glide vehicle. It is not written anywhere that a Boost Glide vehicle can't have a SCRAMJET engine. You would get a rough idea of how HSTDV has been envisioned in this article.

Lockheed to Build a Mach 20 Hypersonic Weapon System

https://www.popularmechanics.com/military/research/a22970/lockheed-hypersonic-weapon/

The rocket boosts TBG to an even higher altitude, whereupon a scramjet or ramjet kicks in and quickly accelerates it up to hypersonic speeds. TBG then glides unpowered the rest of the way to the target.

Do you think SFC would integrate any missile system with just three trials? That too the trial of 2011 i.e, third one is dubbed as production validation trial. From 2008 to 2011 it had undergone three trials including one for production validation. Don't you feel these things fishy?

Moreover Shaurya is an QBM. It doesn't have a ballistic path.

Anyway I have wrote to Arun Vishwakarma enquiring his source for 1800 km range plot.

One test snap of HSTDV......

This looks more like DRDO testing heat shields and other parameters for Shaurya or Pralay. That blue box looks like some kind of motor that is going to make the test vehicle rotate about its axis, the same thing that Shaurya does in-flight to distribute the heat evenly on its surface.

Note what is written on the test article HSTDV

Yes it was to validate the real test trajectory and the stimulated CFD trajectory

I know. That is why its got me confused.

There is also one pic with HSTDV with a part of heat shield removed. Hope @porky_kicker does have that pic.

Unrelated this one's interesting

 

[Arihant Roy]

Ok guys I believe I have the best resolution picture of drdo LRTR (long range tracking radar ) if not the only available picture of LRTR till date.

Enjoy it !

@sayareakd

The range of the LRTR has been increased to 1500 km now. Mate are you absolutely sure this is the Swordfish radar? Coz it looks like a GreenPine ELM-2080 variant.

Thanks for the pic.

Here SCRAMJET is used to sustain the hypersonic, it doesn't need to act as booster for Hypersonic flight, likewise in Zircon. And HSTDV is a technology demonstrator of a Scramjet propulsion which is run by Hydrocarbon fuel, its not the TD for a boost glide vehicle. Boost glide is a successor of RV and is already deployed on Shaurya/K15/K4 if anyone of them are operational .

It was developmental trails, after that it's naval variant K15 were tested and all were in flat trajectory after a ballastic launch. Anyways can you explain what is "QUASI"BM, how it works, trajectory and speed variables during that flight with rocket propulsion.
