Indian Hypersonic Propulsion Developments

Our own Scramjet work will likely result in a different HCM and not BrahMos 2. BrahMos is a JV between India-Russia so sales profit is shared by both nations. BrahMos-2 will happen and it'll likely be Indianized Tisrkon HCM. Our HCM will be a different project, completely different to the hypersonic BrahMos(Zircon MKI) just like STAR is to the current BrahMos.
As far range, Zircon is around 1000kms, so expect our own HCM to be in this ballpark, if not more, as we've already tested our scramjet for over 15 minutes in lab. Let's see how the final version comes out to be.
OfCourse, when you have the technology, why would any nation confine it to a single project. They will try to use it many more product. Hypersonic Scramjet technology is a niche technology, and it becomes unique when you have the capability to run it for a longer duration of time. No doubt that this technology will go into many other weapons and possibly in space application as well.
The govt should fast-track the ISRO HAVA project if they can,
Two key hypersonic projects running parallel will give us an edge
ET-LDHCM (Extended Trajectory- Long duration Hypersonic Cruise missile to be tested in a few months. Will be capable of being launched from air platforms, naval ships, and land-based TELs. Built using entirely domestic tech under Project Vishnu. This clears any doubt that this program is somehow linked to Zircon.
Who even had the idea that this is linked to Zircon ? HSTDV related work has been ongoing since like mid 1990s as per open source literature.
Also ET is not extended trajectory. That's not even a proper term. The trajectory is not extended, rather can be shaped accordingly by various methods. Range can be extended. Here ET means Endothermic , ie the fuel can absorb the generated heat from the surrounding area inside the conbustor without needing a separate coolant.

In fact, one reason why we consider this scramjet is mach 6-7 (so far estimated from open literature) and the russian zircon being mach 9-10 is precisely the below part (from Prof HS Mukunda NPTEL lecture)

If this program fructifies, that's effectively the end of BrahMos-II (which is already in a sort of cold storage). There will no longer be any need to seek foreign collaboration for SCRAMJET technology.
Though I have doubts about the payload capacity of 1-2 tons as mentioned in the article. I don't think that's right.
I estimate it to be in the region of the usual 400 kgs. 2 tons seems to be a gross exaggeration to be honest.
This scramjet program is mainly dual use, ie one is for missile application, and the other is for a hypersonic plane or hyperplane which will be mainly a transport aircraft with scramjet engine. The missile config payload and the transport purpose payload will obviously differ and the latter would carry significant payload mass. Older presentations used to show this, Pillai sir VK Saraswat and others had shown the concept sometimes before.
He's talking about that isro concept
There are 5 WT models and 10 aerodynamic config which have been readied so far.
I recall Dr Kalam talking about this in an article Rediff covered extensively on our Hypersonic program for space civilian & defence applications in 2000 -01 , my FY in Engg college. IIRC , BRF too had articles on it then.
How time flies?! Hopefully we realise this next decade.
It's an HGV,
HGV doesn't comes with waverider configuration only, there are more to it, each HGV offers very distinct characteristics i.e range, velocity, accuracy & maneuverability,
The US already tested AHW,
The fins are added for more lift,
And DRDO doesn't have single HGV, they already have delta winged body,
Conical body, blended body

Again you are doing your usual BS,
Does application of physics changes w.r.t countries?
Explain how the vehicle reached Mach-7 as per you this configuration can't even reach mach-5, how did it pull Mach-7, by the way this was from 2011, is it the Mach-5 & above number is reserved for Chinese weapons,
I guess DRDO scientist are playing super mario in hypersonic test facility
