DRDO and PSU's

[FalconSlayers]

Any updates on BrahMos-II? Heard they were discussing ToT of Tsirkon with Russians.

Looks like it is going to a family of different systems including the land attack and anti ship versions.

Other projects under development:

ET-LDHCM is Project Vishnu a scramjet engine powered hypersonic cruise missile.

Project Dhwani is an unpowered Hypersonic Glide Weapon which will be mounted most probably on a ICBM.

Googled this up and some post by linkedin wala came up

I never knew there was an Atmanirbhar hypersonic program, used to assume they'd just get the Zircon from Russis and call it BrahMos-II

I got ur notion but there was a document with lrashm along hgv
That's the reason why many are believing hgv theory

Ok, but how is this thing supposed to, you know, glide??

Yup; one of most precise weapons to be ever developed by mankind are the KKVs on Anti-Ballistic Missile; second only to sniper rifles. After seperation they lose the forward thrust pretty quickly and simply drift toward the interception point. And for guidance use micro thrusters (or whats technically called a DACS) and even with those achieve God level of precision. The enemy warhead moving kilometres per second, this KV too moving at comparable speed and still manages to engage a target at small as one metre square.

And here we're talking about big ahh warships. Moreover it's not like a ballistic missile that if you miss all hell will break loose...even a near miss by 10m would result in pretty much a mission kill for the warship.

No, absolutely not.
And to answer why and also to address future debates I'm giving a dimensionless number; Ayan's Ratio. Use this to determine what kind of things it's.

In the last separating thing; be it HGV or MIRV or MaRV or whatever this LRAShM is find two things; the weight of the warhead and the weight of the propellant it carries. No divide the propellant by warhead; if less an 1 then glide vehicle and if more than 1 then a powered missile.

Wo sab to thik hai, par ye dara kis ko raha hai be

And your assumption is wrong because you seem to miss the point of me drawing parallel between Rudram-III and this based on the fact that both have quasi ballistic trajectory, both uses separating 1st stage, have minimal wings
It had nothing to do with velocity

Also that Mach 9 would most probably be the re-entry velocity which would decrease from that point as more and more maneuvers are made.

True, totally agreeing with that fact that even with minimal wing you can generate sufficient lift using the speed.

But now I'd ask you do help me in one thing. Take the exact shape of this re-entry vehicle of LR-AShM with its nose cone, long cylindrical body of uniform cross section and small wings...and tell me, will there be any flow separation past the ogive of nose cone?
And if yes, then would sufficient amount of air even reach the wings let alone generating lift.

and who decided that ratio of less than one or more than one decides a glide vehicle? Which agency certified this method of identifying it?
The AHW with it's design will also not be considered a glide vehicle by this definition, as it's top section which will house the warhead is highly tapered and will most likely carry more propellant in weight, yet the american army call it "hypersonic boost-GLIDE vehicle".
Rudram three has "control surfaces" , this one has wings( long fins on the body) and control surfaces at it's tail near the booster.


Yeah, Mach 5 of rudram 3 is also reentry velocity, The same for any other hypersonic thing which is not a cruise missile, the Mach 7-9 speed of dfzf glide vehicle of china is also its reentry speed.


Don't think the amount flow separation that will happen be enough to prevent it from generating sufficient lift.

Its not a blended body glide vehicle like we are used to seeing, but it can glide at hypersonic speed.

Looks like DRDO woke up and started celebrating Diwali.

Happy Diwali Folks

Happy Diwali.

From current progress it seems Indeginous hypersonic cruise missile will comedy before 2.
There's no new development on 2, higher chances are thar it will never come to fruition.

Akhil Bhartiya Vimaan Samandharman Samiti, Prayagraj, Uttar Pradesh

By the way this is the same agency that makes it mandatory to still call a glider "motor glider" and not a "plane" even after you add fuel, engine and a propeller to it.

Rudram three has "control surfaces" , this one has wings( long fins on the body) and control surfaces at it's tail near the booster.

What a sad, stupid hill you've chosen to die on my Guy!

I've always clearly mentioned that why I'm comparing it to Rudram-III and never said IT IS Rudram-III.

drawing parallel

Itna kya dill pe le liye!?

Also whatever tired to say in those wings and control surfaces, made no sense to me. If something moves; it's a control surface. If fixed; it's a wing. And both Rudram and this have pretty similar arrangement of these; mid-body fixed and aft movable.

Don't think the amount flow separation that will happen be enough to prevent it from generating sufficient lift.

Noice...so now it seems you're atleast slowly coming towards what I'm trying to say.
And do some CFD and find accurately, how the air would behave.

 

[Ayan Barat]

2 fins will be vertical and 2 will be horizontal, horizontal fins will generate lift

Achha

And why exactly those fins can't be in X shape!?

Resolve the force generated by each fin into its horizontal and vertical components and then add up all the vertical components.

Hfs, alright my loss, forgot the 10standard vectors.
But still those fins don't need to be aerofoil shape, flat surfaces can still generate lift at an angle.
When the missile descents downwards the horizontal fins can generate lift while the vertical fins will just cut through the air as they are perpendicular to it.

Even I am not convinced with the hgv logic that's why I feel @Ayan Barat ji analogy pretty much accurate
I was stating why people were claiming it to be hgv
But practically it doesn't seem to have warhead(supposedly hgv) separating from missile
Apart from 1st stage which seems to be of k4 entire missile seems to remain intact atleast if we study the poster
