Seems like a legit testing

Yes, but these aren't Ramjet shells but a propulsion module that can be fit in existing shells. The guided integrated ramjet shell project is being built by DRDO and is different from this effort.

Is that interesting? I think the bleed valve increases the range by a similar number. However, a ramjet requires liquid fuel! only?
So what can be possible handling and storage problems in the field?
@CallSignMaverick
 
I dont see great potential in this project

if anything, this will make drone tech. development faster

tech. is a curse sometimes

After all, there are already accurate rockets that can cover the same distance with higher accuracy

whats the point in inventing the wheel twice!

Ramjet tech. has existed since 1950s, there is a reason developed countries paid no heed towards marriage of artillery shells and ramjet engine

A few won't hurt if they can out-range us. Also, if it is a clip-on system, it can be added to rocket artillery (not easily and limited to a few systems) and beyond, like an A2A missile! or am i thinking too much?

I'd rather invest in more heavily in penetrative drones and attack helicopters and drones without GPS

deny air superiority, send drone and helicopters, wipe out whole artillery and tank columns

for a limited defense budget country like us, there is no 'upside' in having these shells, when they are expensive and new

I don't know but we use solid-fuel ramjets in some of our missiles, like Astra Mk-3 (SFDR).

Gives a compact solution to hit farther with little form factor.
Many are working on ramjet arty shells worldwide.

Not all ramjet engines use liquid fuel. There are also ramjet engines that use solid fuel. For example, the engine of the Meteor air-to-air missile uses a solid-fuel ramjet.

sorry, what is a 'form factor', could you explain?

Small size of the munition over a heavy rocket to reach same range.

so, you mean body of a rocket and head of a ramjet artillery shell.
(in other words, extended range rocket artillery)

given the extended range is 30 to 50% (and this means accuracy is lost as well!)

I dont see any point, in doing that either, when, at the same cost air superiority can be established!

although, Im not a military specialist nor i am a artillery specialist

Im only trying to make economical sense out of this!
 
Few corrections

1. This is not a brand new shell but a hybrid propulsion module, which will increase the range by nearly 50 % by replacing the base bleed unit with a hybrid ramjet unit

2. This ramjet is powered by solid fuel, more specifically an aluminium based solid propellent with HTPB based binder

3. DRDO is working on a whole range of next gen shells from scratch independent of these upgrade programs.
Earlier Shells used to nubbed (OFB ERFB shells) where as the new ones will be Bourrelet Shells.

The shells DRDO is working on
1. Standard Bourrelet Shell
2. Base Bleed Shell
3. Hybrid Rocket Assisted Projectile Shell
4. Ramjet Powered Projectile Shell

5. Guided Artillery Shells

4. IIT Madras is also working on a guidence module which would convert existing conventional shells into GPS guided ones. (It's called Indian Smart Ammunition)

Base Bleed Increases the range by 25-30 % whereas this Ramjet Module increase the range by over 50 %

50% is conservative, ranges are almost doubling. Meaning Indian Army won't have to mobilise rocket artillery systems to LoC and can use existing howitzers deployed at LoC to hit as far as outskirts of Islamabad/Rawalpindi or areas in Sialkot and Gujranwala. Pakistan Army with ramjet shells can reach Srinagar.

And this is a propulsion module, additional PGK fuse can be used to reduce CEP. So the cost would be much lower than a complete ramjet shell.

Wow

Grad Rocket range --> 80km+ from 40km
Pinka LRGR Rocket Range --> 250km+ from 120km

Truly revolutionary
