Indian Hypersonic Propulsion Developments

I am tired of Explaining you. Now you have come up with S**T like prolonging Rudram II. What problem do you have with Astra MKII? Whole world is not full that they are spending huge amount of resources on SCRAMJET technologies. It is simply to make a faster and lighter missile which doesn't carry oxidizers with it. No matter which missile is there, efforts will always be boost the range. Brahmos' range is being boosted to 800 k.m from 290 k.m. Why an engine capable of burning 1050 second will be restricted to 250 second or 300 seconds.

My last post in response to your posts.

Read Brahmos MK II instead of Astra MK II.

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
 
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.

The indigenous development of endothermic scramjet fuel, the first time in India, jointly by DRDL and Industry is central to this breakthrough. The fuel offers dual benefits of significant cooling improvement and ease of ignition.

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.

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.
 
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 conceptView attachment 44302
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.

Is this thing an HGV?
Isn't this just adding four lift-enhancing wings to the traditional missile?

This is what is called an HGV.
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

So, what do you think the final speed of this thing in India would be? If you think it's over ten Mach, I can tell you for sure that this configuration simply can't achieve that speed. If you think it's between 2 and 4 Mach, then I agree with your view.
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
